Design with Interpretability in Mind: An Alternate Ethos for Data Science
Abstract: The fields of Machine Learning and Data Science generally follow the paradigm that “the ends justify the means”, where improving predictive power of an algorithm is considered of paramount value, even when implemented at the expense of model intelligibility. While accuracy is an important performance metric, interpretability should be a major consideration for many [...]
What can this robot do? Learning Capability Models from Appearance and Experiments
As autonomous robots become increasingly multifunctional and adaptive, it becomes difficult to determine the extent of their capabilities, i.e. the tasks they can perform and their strengths and limitations at these tasks. A robot's appearance can provide cues to its physical as well as cognitive capabilities. We present an algorithm that builds on these cues [...]

Capturing and Learning Digital Humans
Abstract: The world is shifting towards a digitization of everything -- music, books, movies and news in digital form are common in our everyday lives. Digitizing human beings would redefine the way we think and communicate (with other humans and with machines), and it is necessary for many applications; for example, to transport people into virtual and augmented reality, [...]

Visual Learning with Minimal Human Supervision
Abstract: Machine learning models have led to remarkable progress in visual recognition. A key factor driving this progress is the abundance of labeled data. Unfortunately, this reliance on lots of labeled data is also a key limitation in the rapid development and deployment of vision systems. These visual recognition systems show poor performance on concepts [...]

Search-based Robust Motion Planning under Uncertainty Guided by Multiple Heuristics
Abstract: Motion planning has achieved a great success in many robotic applications but still suffers in the real world under ample uncertainty. For example, manipulation involves interaction with unstructured and stochastic environments, which results in motion uncertainty. Perception that provides understanding of the environment is also not perfect, which in turn leads to sensing uncertainty. [...]

Robust State Estimation for Micro Aerial Vehicles
Title: Robust State Estimation for Micro Aerial Vehicles Autonomous robots provide excellent tools for information gathering in a wide variety of domains, from environmental management to infrastructure inspection and search and rescue. Micro aerial vehicles, in particular, offer a high degree of mobil- ity that can further their effectiveness in such environments. Deployment of aerial [...]
Deep Reinforcement Learning with skill library: Learning and exploration with temporal abstractions using coarse approximate dynamics models
Reinforcement learning is a computational approach to learn from interaction. However, learning from scratch using reinforcement learning requires exorbitant number of interactions with the environment even for simple tasks. One way to alleviate the problem is to reuse previously learned skills as done by humans. This thesis provides frameworks and algorithms to build and reuse [...]
Deformable models meet deep learning: supervised and unsupervised approaches
Abstract: In this talk I will be presenting recent work on combining ideas from deformable models with deep learning. I will start by describing DenseReg and DensePose, two recently introduced systems for establishing dense correspondences between 2D images and 3D surface models ``in the wild'', namely in the presence of background, occlusions, and multiple objects. [...]
Building Scalable Framework and Environment of Reinforcement Learning
Abstract: Deep Reinforcement Learning (DRL) has made strong progress in many tasks that are traditionally considered to be difficult, such as complete information games, navigation, architecture search, etc. Although the basic principle of DRL is quite simple and straightforward, to make it work often requires substantially more samples with more computational resource, compared to traditional [...]
