CSA: Data-efficient Mapping of Unimodal Features to Multimodal Features

ICLR 2025poster

Multimodal encoders like CLIP excel in tasks such as zero-shot image classification and cross-modal retrieval. However, they require excessive training data. We propose canonical similarity analysis (CSA), which uses two unimodal encoders to replicate multimodal encoders using limited data. CSA maps…

Exploiting Distribution Constraints for Scalable and Efficient Image Retrieval

ICLR 2025poster

Image retrieval is crucial in robotics and computer vision, with downstream applications in robot place recognition and vision-based product recommendations. Modern retrieval systems face two key challenges: scalability and efficiency. State-of-the-art image retrieval systems train specific neural n…

VIBE: Annotation-Free Video-to-Text Information Bottleneck Evaluation for TL;DR

NeurIPS 2025poster

Many decision-making tasks, where both accuracy and efficiency matter, still require human supervision. For example, tasks like traffic officers reviewing hour-long dashcam footage or researchers screening conference videos can benefit from concise summaries that reduce cognitive load and save time.…

PEERNet: An End-to-End Profiling Tool for Real-Time Networked Robotic Systems

IROS 2024poster

Networked robotic systems balance compute, power, and latency constraints in applications such as self-driving vehicles, drone swarms, and teleoperated surgery. A core problem in this domain is deciding when to offload a computationally expensive task to the cloud, a remote server, at the cost of co…

Task-aware Distributed Source Coding under Dynamic Bandwidth

NeurIPS 2023poster

Efficient compression of correlated data is essential to minimize communication overload in multi-sensor networks. In such networks, each sensor independently compresses the data and transmits them to a central node. A decoder at the central node decompresses and passes the data to a pre-trained mac…

Decentralized Data Collection for Robotic Fleet Learning: A Game-Theoretic Approach

CoRL 2022poster

Fleets of networked autonomous vehicles (AVs) collect terabytes of sensory data, which is often transmitted to central servers (the ``cloud'') for training machine learning (ML) models. Ideally, these fleets should upload all their data, especially from rare operating contexts, in order to train rob…
