Transitioning from Historian to AI Researcher
Amir Bahr, a PhD candidate at Tel Aviv University and UC Berkeley, delves into the fascinating journey that led him from studying Middle Eastern history to pursuing deep learning and AI research. His transition to the tech industry involved automating the analysis of x-ray and CT scans, followed by establishing and leading an AI team in the Bay Area, ultimately setting the stage for his current pursuit of open-ended research as a PhD candidate.
Importance of Visual Representations in AI Research
Amir Bahr's research focuses on learning visual representations before integrating language, drawing inspiration from how human evolution prioritized visual sensory capabilities over language development. By emphasizing vision-first AI models, Amir aims to enhance understanding of unlabeled data like images and videos, paving the way for more comprehensive learning architectures.
EgoPet Dataset and Vision-to-Proprioception Prediction
Amir Bahr's innovative use of the EgoPet dataset aims to train AI models for various tasks, including visual interaction prediction and vision-to-proprioception prediction. By pretraining models on EgoPet, he seeks to improve performance on tasks requiring interaction analysis and locomotion prediction, highlighting the dataset's value in advancing AI research.
Future Applications of EgoPet Data and Quadruped Robot Learning
Amir Bahr envisions leveraging the EgoPet dataset to cultivate policies for quadruped robots, allowing for advanced visual navigation and interaction capabilities. While current robotics achievements showcase basic control and locomotion, the goal is to enhance robots' abilities to autonomously navigate environments, engage in social interactions, and deliver nuanced tasks beyond predefined trajectories, emphasizing the potential for further AI innovation.
Today, we're joined by Amir Bar, a PhD candidate at Tel Aviv University and UC Berkeley to discuss his research on visual-based learning, including his recent paper, “EgoPet: Egomotion and Interaction Data from an Animal’s Perspective.” Amir shares his research projects focused on self-supervised object detection and analogy reasoning for general computer vision tasks. We also discuss the current limitations of caption-based datasets in model training, the ‘learning problem’ in robotics, and the gap between the capabilities of animals and AI systems. Amir introduces ‘EgoPet,’ a dataset and benchmark tasks which allow motion and interaction data from an animal's perspective to be incorporated into machine learning models for robotic planning and proprioception. We explore the dataset collection process, comparisons with existing datasets and benchmark tasks, the findings on the model performance trained on EgoPet, and the potential of directly training robot policies that mimic animal behavior.
