VCR seminar will hold a workshop for AAAI visitors from other universities. Below is the schedule for the talks.
Talk 1 (11 am-11:40) Levi Lelis, Department of Computing Science, University of Alberta
Title: Learning Options by Extracting Programs from Neural Networks
Abstract: In this talk, I argue for a programmatic mindset in reinforcement learning, proposing that agents should generate libraries of programs encoding reusable behaviors. When faced with a new task, the agent learns how to combine existing programs and generate new ones. This approach can be helpful even when policies are encoded in seemingly non-decomposable representations like neural networks. I will show that neural networks with piecewise linear activation functions can be mapped to a program with if-then-else structures. Such a program can then be easily decomposed into sub-programs with the same input type of the original network. In the case of networks encoding policies, each sub-program can be seen as an option—a temporally extended action. All these sub-programs form a library of agent behaviors that can be reused later, in downstream tasks. Considering that even small networks can encode a large number of sub-programs, we select sub-programs that are likely to generalize to unseen tasks. This is achieved through a subset selection procedure that minimizes the Levin loss. Empirical evidence from challenging exploration scenarios in two grid-world domains demonstrates that our methodology can extract helpful programs, thus speeding up the learning process in tasks that are similar and yet distinct from the one used to train the original model.
Bio: Dr. Levi Lelis is an Assistant Professor at the University of Alberta, an Amii Fellow, and a CIFAR AI Chair. Levi’s research is dedicated to the development of principled algorithms to solve combinatorial search problems. These problems are integral to optimizing tasks in various sectors. Levi’s research group is focused on combinatorial search problems arising from the search for programmatic solutions—computer programs written in a domain-specific language encoding problem solutions. Levi believes that the most promising path to creating agents that learn continually, efficiently, and safely is to represent the agents’ knowledge programmatically. While programmatic representations offer many advantages, including modularity and reusability, they present a significant challenge: the need to search over large, non-differentiable spaces not suited for gradient descent methods. Addressing this challenge is the current focus of Levi’s work.
Talk 2 (11:40 am-12:20) Vahid Babaei , Max Planck Institute for Informatics
Title: Inverse Design with Neural Surrogate Models
Abstract: The digitalization of manufacturing is turning fabrication hardware into computers. As traditional tools, such as computer aided design, manufacturing, and engineering (CAD/CAM/CAE) lag behind this new paradigm, the field of computational fabrication has recently emerged from computer graphics to address this knowledge gap with a computer-science mindset. Computer graphics is extremely powerful in creating content for the virtual world. The connection is therefore a natural one as the digital fabrication hardware is starving for innovative content. In this talk, I will focus on inverse design, a powerful paradigm of content synthesis for digital fabrication, which creates fabricable designs given the desired performances. Specifically, I will discuss a class of inverse design problems that deals with data-driven neural surrogate models. These surrogates learn and replace a forward process, such as a computationally heavy simulation.
Bio: Vahid Babaei leads the AI aided Design and Manufacturing group at the Computer Graphics Department of the Max Planck Institute for Informatics in Saarbrücken, Germany. He was a postdoctoral researcher at the Computational Design and Fabrication Group of Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT.

He is interested in developing original computer science methods for both engineering design and advanced manufacturing.
Talk 3 (1 pm -1:40 pm) Sven Koenig, computer science department, University of Southern California
Title: Multi-Agent Path Finding and Its Applications
Abstract: The coordination of robots and other agents becomes more and more important for industry. For example, on the order of one thousand robots already navigate autonomously in Amazon fulfillment centers to move inventory pods all the way from their storage locations to the picking stations that need the products they store (and vice versa). Optimal and even some approximately optimal path planning for these robots is NP-hard, yet one must find high-quality collision-free paths for them in real-time. Algorithms for such multi-agent path-finding problems have been studied in robotics and theoretical computer science for a longer time but are insufficient since they are either fast but of insufficient solution quality or of good solution quality but too slow. In this talk, I will discuss different variants of multi-agent path-finding problems, cool ideas for both solving them and executing the resulting plans robustly, and several of their applications. Our research on this topic has been funded by both NSF and Amazon Robotics.
Bio: Sven Koenig is a professor of computer science at the University of Southern California. Most of his current research focuses on planning for single agents (such as robots) or multi-agent systems. Additional information about him can be found on his webpages: idm-lab.org.
Talk 4 (1:40 pm -2:20 pm) Jiaoyang Li, Robotics Institute, Carnegie Mellon University
Title: Layout Design for Large-Scale Multi-Robot Coordination
Abstract: Today, thousands of robots are navigating autonomously in warehouses, transporting goods from one location to another. While numerous planning algorithms are developed to coordinate robots more efficiently and robustly, warehouse layouts remain largely unchanged – they still adhere to the traditional pattern designed for human workers rather than robots. In this talk, I will share our recent progress in exploring layout design and optimization to enhance large-scale multi-robot coordination. I will first introduce a direct layout design method, followed by a method to optimize layout generators instead of layouts. I will then extend these ideas to virtual layout design, which does not require changes to the physical world that robots navigate and thus has the potential for applications beyond automated warehouses.
Bio: Jiaoyang Li is an assistant professor at the Robotics Institute of CMU School of Computer Science. She received her Ph.D. in computer science from the University of Southern California (USC) in 2022. Her research interests lie in the coordination of large robot teams.

Title: Co-speech gesture generation
Abstract: Gestures accompanying speech are essential to natural and efficient embodied human communication. The automatic generation of such co-speech gestures is a long-standing problem in computer animation. It is considered an enabling technology in film, games, virtual social spaces, and interaction with social robots. The problem is made challenging by the idiosyncratic and non-periodic nature of human co-speech gesture motion, and by the great diversity of communicative functions that gestures encompass. Gesture generation has seen surging interest recently, owing to the emergence of more and larger datasets of human gesture motion, combined with strides in deep-learning-based generative models that benefit from the growing availability of data. This talk will review co-speech gesture generation research development, focusing on deep generative models.

Title: Quantum Computing for Robust Fitting
Abstract: Many computer vision applications need to recover structure from imperfect measurements of the real world. The task is often solved by robustly fitting a geometric model onto noisy and outlier-contaminated data. However, relatively recent theoretical analyses indicate that many commonly used formulations of robust fitting in computer vision are not amenable to tractable solution and approximation. In this paper, we explore the usage of quantum computers for robust fitting. To do so, we examine the feasibility of two types of quantum computer technologies—universal gate quantum computers and quantum annealers—to solve robust fitting. Novel algorithms that are amenable to the quantum machines have been developed, and experimental results on current noisy intermediate scale quantum computers (NISQ) will be reported. Our work thus proposes one of the first quantum treatments of robust fitting for computer vision.

Title: Efficient, Less-biased and Creative Visual Learning
Abstract: In this talk I will discuss recent methods from my group that focus on addressing some of the core challenges of current visual and multi-modal cognition, including efficient learning, bias and user-controlled generation. Centering on these larger themes I will talk about a number of strategies (and corresponding papers) that we developed to address these challenges. I will start by discussing transfer learning techniques in the context of a semi-supervised object detection and segmentation, highlighting a model that is applicable to a range of supervision: from zero to a few instance-level samples per novel class. I will then talk about our recent work on building a foundational image representation model by combining two successful strategies of masking and sequential token prediction. I will also discuss some of our work on scene graph generation which, in addition to improving overall performance, allows for scalable inference and ability to control data bias (by trade off major improvements on rare classes for minor declines on most common classes). The talk will end with some of our recent work on generative modeling which focuses on novel-view synthesis and language-conditioned diffusion-based story generation. The core of the latter approach is visual memory that implicitly captures the actor and background context across the generated frames. Sentence-conditioned soft attention over the memories enables effective reference resolution and learns to maintain scene and actor consistency when needed.

Title: Towards Controllable 3D Content Creation by leveraging Geometric Priors
Abstract: The growing popularity for extended realities pushes the demand for the automatic creation and synthesis of new 3D content that would otherwise be a tedious and laborious process. A key property needed to make 3D content creation useful is user controllability as it allows one to realize specific ideas. User-control can be of various forms, e.g. target scans, input images or programmatic edits etc. In this talk, I will be touching works that enable user-control through i) object parts and ii) sparse scene images by leveraging geometric priors. The former utilizes object semantic priors by proposing a novel shape space factorization through an introduced cross diffusion network that enabled multiple applications in both shape generation and editing. The latter leverages pretrained models of large 2D datasets for sparse view 3D NeRF reconstruction of scenes by learning a distribution of geometry represented as ambiguity-aware depth estimates. As an add-on, we will also briefly revisit the volume rendering equation in NeRFs and reformulate it to piecewise linear density that alleviates underlying issues caused by quadrature instability.

Title:
Shading Languages and the Emergence of Programmable Graphics Systems
Abstract:
A major challenge in using computer graphics for movies and games is to create a rendering system that can create realistic pictures of a virtual world. The system must handle the variety and complexity of the shapes, materials, and lighting that combine to create what we see every day. The images must also be free of artifacts, emulate cameras to create depth of field and motion blur, and compose seamlessly with photographs of live action.
Pixar's RenderMan was created for this purpose, and has been widely used in feature film production. A key innovation in the system is to use a shading language to procedurally describe appearance. Shading languages were subsequently extended to run in real-time on graphics processing units (GPUs), and now shading languages are widely used in game engines. The final step was the realization that the GPU is a data-parallel computer, and the the shading language could be extended into a general-purpose data-parallel programming language. This enabled a wide variety of applications in high performance computing, such as physical simulation and machine learning, to be run on GPUs. Nowadays, GPUs are the fastest computers in the world. This talk will review the history of shading languages and GPUs, and discuss the broader implications for computing.

Title: Diffusion Models: From Foundations to Image, Video and 3D Content Creation
Abstract: Denoising diffusion-based generative models have led to multiple breakthroughs in deep generative learning. In this talk, I will provide an overview over recent works by the NVIDIA Toronto AI Lab on diffusion models and their applications for digital content creation. I will start with a short introduction of diffusion models and recapitulate their mathematical formulation. Then, I will briefly discuss our foundational works on diffusion models, which includes advanced diffusion processes for faster and smoother diffusion and denoising, techniques for more efficient model sampling, as well as latent space diffusion models, a flexible diffusion model framework that has been widely used in the literature. Moreover, I will discuss works that use diffusion models for image, video and 3D content creation. This includes large text-to-image models as well as recent work on high resolution video synthesis with latent diffusion models. I will also summarize some of our efforts on 3D generative modeling. This includes object-centric 3D synthesis by training diffusion models on geometric shape datasets or leveraging large-scale text-to-image diffusion models as priors for shape distillation, as well as full scene-level generation with hierarchical latent diffusion models.

Title: MyStyle: A Personalized Generative Prior
Time: Friday, May 6th at 11:00 AM PST
Abstract: Deep generative models have proved to be successful for many image-to-image applications. Such models hallucinate information based on their large and diverse training datasets. Therefore, when enhancing or editing a portrait image, the model produces a generic and plausible output, but often it isn’t the person who actually appears in the image. In this talk, I’ll present our latest work, MyStyle - which introduces the notion of a personalized generative model. Trained on ~100 images of the same individual, MyStyle learns a personalized prior, custom to their unique appearance. This prior is then leveraged to solve ill-posed image enhancement and editing tasks - such as super-resolution, inpainting and changing the head pose.

Title: SAPE: Spatially-Adaptive Progressive Encoding for Neural Optimization
Time: Wednesday, Nov 3, 1:30 PM
Abstract: Multilayer-perceptrons (MLP) are known to struggle with learning functions of high-frequencies, and in particular cases with wide frequency bands. We present a spatially adaptive progressive encoding (SAPE) scheme for input signals of MLP networks, which enables them to better fit a wide range of frequencies without sacrificing training stability or requiring any domain specific preprocessing. SAPE gradually unmasks signal components with increasing frequencies as a function of time and space. The progressive exposure of frequencies is monitored by a feedback loop throughout the neural optimization process, allowing changes to propagate at different rates among local spatial portions of the signal space. We demonstrate the advantage of SAPE on a variety of domains and applications, including regression of low dimensional signals and images, representation learning of occupancy networks, and a geometric task of mesh transfer between 3D shapes.

Title: Recent Advancements in StyleGAN Inversion
Time: Wednesday, August 11, 10AM
Abstract: StyleGAN has recently been established as the state-of-the-art unconditional generator, synthesizing images of phenomenal realism and fidelity. With its rich semantic space, many works have attempted to understand and control StyleGAN’s latent representations with the goal of performing image manipulations. To perform manipulations on real images, however, one must learn to “invert” the GAN and encode a given image into StyleGAN’s latent space, which remains an open challenge. In this talk, we will discuss recent techniques and advancements in GAN Inversion and explore their importance for real image editing applications. In addition, going beyond the inversion task, we demonstrate how StyleGAN can be used for performing a wide range of image-to-image translation tasks.

Talk title: Self–Adaptive Visual Learning
Time: April 23, from 3:30 to 4:30PM (PST)
Abstract: There have been significant advances in computer vision in the past few years. Despite the success, current computer vision systems are still hard to use or deploy in many real-world scenarios. In particular, current computer vision systems usually learn a generic model. But in real world applications, a single generic model is often not powerful enough to handle the diverse scenarios. In this talk, I will introduce some of our recent work on self-adaptive visual learning. Instead of learning and deploying one generic model, our goal is to learn a model that can effectively adapt itself to different environments during testing. I will present applications from several computer visions, such as crowd counting, anomaly detection, personalized highlight detection, etc.

Talk title: AI Agents that can Collaborate and Communicate in Virtual Visual Worlds
Time: April 16, from 3:30 to 4:30PM (PST)
Abstract: The past decade in artificial intelligence, particularly computer vision, has been about hammering passively collected datasets with massive deep learning models. As the race to boost metrics on them is saturating, researchers like me are working on visual or embodied AI agents that draw inspiration from how toddlers acquire intelligence, i.e., by exploring, interacting, and navigating in their environments.
Particularly, I am excited to study how visual embodied agents can learn key skills of social intelligence – collaboration and communication. In this talk, I’ll discuss how we are building AI Agents that can collaborate and communicate in virtual visual worlds. Moreover, I’ll discuss how simplistic gridworlds and visual worlds can be connected with a ‘GridToPix’ methodology. The relevant papers can be found on my webpage.

Talk title: Towards Machines that Understand Geometry
Time: April 9, from 3:30 to 4:30PM (PST)
Abstract: Understanding the how the worlds looks like and interacting with the environment is a core ability of an intelligent being. Naturally, it has been a long-lasting research topic in Computer Vision. The capacity of machines in figuring out surrounding geometry has increased dramatically over the last decade, so much so that self-driving cars and autonomous drones are not a distant future. However, the “last mile” has shown to be more difficult than anticipated, delaying the arrival of these machines. Machine learning, like many other applications, have very recently started to help in this regard, again creating a leap from what it could do just a couple years back.
In this talk, I will introduce our journey towards machines that understand geometry. I will show that by combining our knowledge about the physical world with machine learning, we can achieve much more than a black-box solution. Specifically, I will show how we use non-differentiable components within deep networks and still train as a whole; how we constrain the network to follow physics via deep network architectures and formulations; how we can tailor architectures for solving image correspondence problems; and how we simplify the role of machine learning by turning the problem into hypothesis testing.

Talk title: Learning 3D Shape Actionable Information from Simulated Interaction
Time: April 2, from 3:30 to 4:30PM (PST)
Abstract: We humans accomplish everyday tasks by interacting with a wide range of 3D objects, with diverse geometry, rich semantics, and complicated structures. One fundamental goal of computational visual perception is to equip intelligent agents with similar capabilities to understand how to meaningfully interact with the 3D environment. While great advances have been achieved in both fields of 3D vision (e.g. object detection, pose estimation, shape reconstruction) and robotic manipulation (e.g. planning, control), we ask the question – what are good visual representations of 3D shapes for various downstream robotic manipulation tasks? In this talk, I will introduce my recent research taking one step along this direction that learns 3D shape actionable information via large-scale annotation-free learning from simulated interaction. More specifically, I will present two works (i.e. Where2Act, O2O-Afford) that learn 3D shape visual affordance post-conditioned on various primitive manipulation policies, using the large-scale ShapeNet/PartNet dataset and SAPIEN physical simulation environment.

Talk title: Building Blocks of Generalizable Autonomy in Robot Manipulation
Time: March 19, from 3:30 to 4:30PM (PST)
Abstract: My approach to Generalizable Autonomy posits that interactive learning across families of tasks is essential for discovering efficient representation and inference mechanisms. Arguably, a cognitive concept or a dexterous skill should be reusable across task instances to avoid constant relearning. It is insufficient to learn to “open a door”, and then have to re-learn it for a new door, or even windows & cupboards. Thus, I focus on three key questions- (1) Representational biases for embodied reasoning, (2) Causal Inference in abstract sequential domains, and (3) Interactive Policy Learning under uncertainty. In this talk, I will first through example lay bare the need for structured biases in modern RL algorithms in the context of robotics. This will span state, actions, learning mechanisms, and network architectures. Secondly, we will talk about the discovery of latent causal structure in dynamics for planning. Finally, I will demonstrate how large-scale data generation combined with insights from structure learning can enable sample efficient algorithms for practical systems. In this talk, I will focus mainly on manipulation, but my work has been applied to surgical robotics and legged locomotion as well.

Talk title: Generation by Decomposition
Time: December 16, from 1:30 to 2:30PM (PST)
Abstract: Deep learning has revolutionized our ability to generate novel images and 3D shapes. Neural networks are typically trained to map a high-dimensional latent code to full realistic samples. In this talk, I will present two recent works focusing on generation of handwritten text and 3D shapes. In these works, we take a different approach and generate image and shape samples using a more granular part-based decomposition, demonstrating that the whole is not necessarily “greater than the sum of its parts”. I will also discuss how our generation by decomposition approach allows for a semantic manipulation of 3D shapes and improved handwritten text recognition performance.

Title: Category-Level Object Perception for Physical Interaction
Time: 1:30 - 2:30, Wednesday, September 23
Abstract: Deep neural networks have shown great success both in semantic perception tasks, e.g. object recognition and semantic segmentation, and in end-to-end perception for reinforcement learning and robotic tasks. However, it is still unclear how to bridge these two perception paradigms to gain a deep semantic and interaction-driven understanding of physical interaction.
In this talk, I will focus on how to explore categorical actionable information for the sake of perceiving and understanding physical interactions. First, I will show that learning high-level semantic actionable information, e.g. object state, can help with action planning. Second, I will introduce the problem of estimating category-level 6D pose and 3D size for rigid objects. This category pose can be seen as low-level actionable information and can benefit object manipulation tasks. Lastly, I will present my recent works on curating an articulated object dataset and estimating category-level articulated object pose.
Bio: He Wang is a fifth-year PhD student at Stanford University under the supervision of Prof. Leonidas Guibas. His research interests span across computer vision, geometric computing, and robotics.

“Reconstructing the detailed and complete 3D surface of an object from a single 2D image is a long standing computer vision problem. In this talk, we present an inverse graphics-based framework to learn a 3D face model from a large set of in-the-wild 2D face images, without the need of capturing 3D scans. We also extend this framework to high-fidelity face modeling, as well as generic object modeling and 3D reconstruction. In the end, we will briefly overview other research efforts in the Computer Vision Lab at Michigan State University, including face anti-spoofing, explainable recognition, early sensor fusion of LiDAR and RGB, 2D/3D object detection from urban driving videos, etc.”

The GrUVi team congratulates Kangxue Yin, whom received the prestigious Chinese Government Award for Outstanding Self-financed Students Abroad!
This award was established in 2003 by the China Scholarship Council. The worldwide recipients are chosen annually based on a record of outstanding accomplishments in any discipline.
This award is considered the highest award given by Chinese government for Chinese graduate students studying abroad who do not receive regular financial support from Chinese government.
Currently, this award is granted to only 500 students every year. Since there are around half a million Chinese students to study abroad per year, this a highly competitive award. For the academic year 2018, only 6 awardees were based in British Columbia, Canada. Among them, Kangxue was the only student majoring in Computer Science.

Two gruviers were student volunteers (SV) at the SIGGRAPH 2018 conference. While the attendees were certainly thankful for all the work that all the volunteers put in the event, our gruvi volunteers described how valuable the experience was for them! Zhiqin got the chance to use the hardware available at the exhibition hall to print the awesome gruvi logo on the hat shown in the picture. He described the great impact that experiencing the latest developments on VR technology had on him:
“I’m honored to be a student volunteer of such a great conference. VR was definitely a highlight of SIGGRAPH 2018. There were many showcases of applying haptic technology to VR and utilizing VR for designing and creating content. The immersive pavilion was awesome and provided me all kinds of VR experiences. I am looking forward to next SIGGRAPH!”
Akshay, on the other hand, emphasized the connections he was able to forge during his time as a volunteer:
“This was my first SIGGRAPH and my first time as a SIG-SV. The kind of atmosphere, the exuberance of energy and experience that I felt was surreal and I was left wanting for more when it ended. Memories of a lifetime with awesome fellow SV’s, coordinating various programs and above all, the latest technology!! Definitely want to relive this again at SIG’19.”

Congrats to Jaime for successfully defending his MSC thesis on “Towards Learning of a Joint Geometry-Structure Manifold for Shape Exploration”.
Here is the abstract of his thesis.
We present a first attempt at producing a continuous generative model of 3D objects from a joint representation that incorporates the discrete structural variability as well as the continuous geometric variability that are often present in collections of man-made shapes. Starting from a set of compatibly segmented shapes, our main contribution consists in demonstrating the construction of the joint representation. Then, by using Gaussian Process learning to produce a predictive manifold from the joint representation, we investigate its capabilities and limitations for reproducing and synthesizing new shapes.

Congrats to Warunika for successfully defending her MSc thesis on “ExquiMo: An Exquisite Corpse Tool for Co-Creative 3D Shape Modeling”. The researchers would like to assure you that no person, dog, or any other animals were killed as the result of conducting this thesis research.
Here is the abstract of her work:
We introduce a shape modeling tool, ExquiMo, which is guided by the idea of improving the creativity of 3D shape designs through collaboration. Inspired by the game of Exquisite Corpse, our tool allocates distinct parts of a shape to multiple players who model the assigned parts in a sequence. Our approach is motivated by the understanding that effective surprise leads to creative outcomes. Hence, to maintain the surprise factor of the output, we conceal the previously modeled parts from the most recent player. Part designs from individual players are fused together to produce an often unexpected, hence creative, end result. We demonstrate the effectiveness of collaborative modeling for both man-made and natural shapes. Our results show that, when compared to models designed by individual users, multi-user collaborative modeling via ExquiMo tends to lead to more creative designs in terms of the most common criteria used to identify creative artifacts.
