LLMPopcorn: Exploring LLMs as Assistants for Popular Micro-video Generation

ICASSP 2026poster

In an era where micro-videos dominate platforms like TikTok and YouTube, AI-generated content is nearing cinematic quality. The next frontier is using large language models (LLMs) to autonomously create viral micro-videos, a largely untapped potential that could shape the future of AI-driven content…

Seeing Eye to AI: Human Alignment via Gaze-Based Response Rewards for Large Language Models

ICLR 2025poster

Advancements in Natural Language Processing (NLP), have led to the emergence of Large Language Models (LLMs) such as GPT, Llama, Claude, and Gemini, which excel across a range of tasks but require extensive fine-tuning to align their outputs with human expectations. A widely used method for achievin…

Overcoming Catastrophic Forgetting with Hard Attention to the Task

ICML 2018oral

Catastrophic forgetting occurs when a neural network loses the information learned in a previous task after training on subsequent tasks. This problem remains a hurdle for artificial intelligence systems with sequential learning capabilities. In this paper, we propose a task-based hard attention mec…

On Context-Dependent Clustering of Bandits

ICML 2017poster

We investigate a novel cluster-of-bandit algorithm CAB for collaborative recommendation tasks that implements the underlying feedback sharing mechanism by estimating user neighborhoods in a context-dependent manner. CAB makes sharp departures from the state of the art by incorporating collaborative…
