Fast Hierarchical Learning for Few-Shot Object Detection

2022 · arXiv (Cornell University)

Transfer learning based approaches have recently achieved promising results on the few-shot detection task. These approaches however suffer from ``catastrophic forgetting'' issue due to finetuning of base detector, leading to sub-optimal performance on the base …

A Multiplicative Value Function for Safe and Efficient Reinforcement Learning

2023 · arXiv (Cornell University)

An emerging field of sequential decision problems is safe Reinforcement Learning (RL), where the objective is to maximize the reward while obeying safety constraints. Being able to handle constraints is essential for deploying RL agents …
