Deep Reinforcement Learning in 3D Environments Devendra Chaplot MLD Abstract In this talk, I will present our research on training autonomous agents to perform a variety of tasks in simulated 3D environments using deep reinforcement learning. In the first part of the talk, I will highlight our work on learning to navigate and play deathmatches in Doom using auxiliary tasks and domain randomization.
In the second part, I will talk about training autonomous agents to follow language instructions using a novel Gated-Attention mechanism for multimodal fusion of representations of verbal and visual modalities. We show that our agent learns to ground each concept of the instruction in visual elements of the environment and is able to generalize well to unseen instructions.
The proposed model incorporates ideas of traditional filtering-based localization methods, by using a structured belief of the state with multiplicative interactions to propagate belief, and combines it with a policy model to localize accurately while minimizing the number of steps required for localization.

April 30 Attention and Activities in First Person Vision Yin Li RI Abstract Advances in sensor miniaturization, low-power computing, and battery life have enabled the first generation of mainstream wearable cameras.
Millions of hours of videos have been captured by these devices, creating a record of our daily visual experiences at an unprecedented scale. This has created a major opportunity to develop new capabilities in vision and learning, based on First Person Vision FPV --the automatic analysis of videos captured from wearable cameras.
My research focuses on understanding naturalistic daily activities of the camera wearer in FPV to advance both computer vision and mobile health. In the first part of this talk, I will demonstrate that first person video has the unique property of encoding the intentions and goals of the camera wearer.
Finally, I will briefly cover my work on cross-modal learning using deep models. April 23 Learning to learn from simulation: Using simulations to expedite learning on robots Akshara Rai RI Abstract In this talk, I will describe our work on using simulation to speed-up learning on actual robots by utilizing domain knowledge.
Robot controllers are often expert-designed policies, which require tuning of parameters for new task scenarios. Bayesian optimization BO is a promising approach for automatically tuning such robot controllers sample-efficiently.
However, when tuning high-dimensional policies on hardware, traditional BO can still be prohibitively expensive.
To overcome this, we develop an approach that utilizes simulation to map the original parameter space into a domain-informed space. During BO, similarity between controllers is now calculated in this transformed space, thus informing the search for optimal parameters based on behavior in simulation.
Experiments on the ATRIAS robot hardware and another bipedal robot simulation show that our approach succeeds at sample-efficiently learning controllers for multiple robots.
What if the simulation significantly differs from hardware? To answer this, we create increasingly approximate simulators and study the effect of increasing simulation-hardware mismatch on the performance of Bayesian optimization.
Our experiments show that our approach succeeds across different controller types, bipedal robot models and simulator fidelity, making it applicable to a wide range of bipedal locomotion problems. April 16 Visual Dialog -- Moving towards agents that can see and talk Satwik Kottur ECE Abstract In light of the unprecedented advances in computer vision CV and artificial intelligence AIthe next generation of visual intelligence systems will need to posses the ability to hold a meaningful dialog with humans in natural language about visual content.
Visual Dialog is disentangled enough from a specific downstream task so as to serve as a general test of machine intelligence, while being grounded in vision enough to allow objective evaluation of individual responses and benchmark progress.
In the first part of the talk, I will motivate the need for Visual Dialog, describe a novel two-person chat data collection protocol to curate a large-scale dataset VisDialpropose retrieval-based evaluation protocol, and develop a family of encoder-decoder models for Visual Dialog.
In the second part, I will talk about how we can extend Visual Dialog to train cooperative, goal-driven dialog agents, using both supervised SL and reinforcement learning RL paradigms.
April 9 Improving the Statistical Efficiency of Machine Reading Comprehension Bhuwan Dhingra LTI Abstract Machine reading aims to automatically read natural language text and extract its information to answer user queries or populate structured databases.
Deep networks trained by supervised learning over large datasets show remarkable performance on these tasks, however their performance goes down rapidly as the amount of supervision is reduced.
This is problematic for specialized domains where labeled data can be expensive to collect. In this talk I will show how we can leverage prior knowledge from external resources to improve the statistical efficiency of deep machine reading systems.
In the first part I will describe a model which uses linguistic annotations from NLP tools, such as coreference resolvers, to bias the reading model towards long-term dependencies in text. In the second part, I will describe a semi-supervised approach which pre-trains the reading model to detect paraphrase phenomena in unlabeled documents.processors free download.
