Active Reinforcement Learning Strategies for Offline Policy Improvement

AAAI 2025technical

Learning agents that excel at sequential decision-making tasks must continuously resolve the problem of exploration and exploitation for optimal learning. However, such interactions with the environment online might be prohibitively expensive and may involve some constraints, such as a limited budge…

One Encoder to Rule them All: Representation Learning for Model-free Visual Reinforcement Learning using Fourier Neural Operators

ICCV 2025poster

Representation learning lies at the core of deep reinforcement learning. Although CNNs have traditionally served as the primary models for encoding image observations, modifying the encoder architecture introduces challenges, especially due to the necessity of determining a new set of hyperparameter…

CRUSH: Contextually Regularized and User anchored Self-supervised Hate speech Detection

NAACL 2022findings

The last decade has witnessed a surge in the interaction of people through social networking platforms. While there are several positive aspects of these social platforms, their proliferation has led them to become the breeding ground for cyber-bullying and hate speech. Recent advances in NLP have o…

Active2 Learning: Actively reducing redundancies in Active Learning methods for Sequence Tagging and Machine Translation

NAACL 2021long

While deep learning is a powerful tool for natural language processing (NLP) problems, successful solutions to these problems rely heavily on large amounts of annotated samples. However, manually annotating data is expensive and time-consuming. Active Learning (AL) strategies reduce the need for hug…
