PreFLMR: Scaling Up Fine-Grained Late-Interaction Multi-modal Retrievers

1 code implementation13 Feb 2024 Weizhe Lin, Jingbiao Mei, Jinghong Chen, Bill Byrne

Large Multimodal Models (LMMs) excel in natural language and visual understanding but are challenged by exacting tasks such as Knowledge-based Visual Question Answering (KB-VQA) which involve the retrieval of relevant information from document collections to use in shaping answers to questions.

Improving hateful memes detection via learning hatefulness-aware embedding space through retrieval-guided contrastive learning

no code implementations14 Nov 2023 Jingbiao Mei, Jinghong Chen, Weizhe Lin, Bill Byrne, Marcus Tomalin

Finally, we demonstrate a retrieval-based hateful memes detection system, which is capable of making hatefulness classification based on data unseen in training from a database.

Fine-grained Late-interaction Multi-modal Retrieval for Retrieval Augmented Visual Question Answering

1 code implementation NeurIPS 2023 Weizhe Lin, Jinghong Chen, Jingbiao Mei, Alexandru Coca, Bill Byrne

FLMR addresses two major limitations in RA-VQA's retriever: (1) the image representations obtained via image-to-text transforms can be incomplete and inaccurate and (2) relevance scores between queries and documents are computed with one-dimensional embeddings, which can be insensitive to finer-grained relevance.

BayesFT: Bayesian Optimization for Fault Tolerant Neural Network Architecture

no code implementations30 Sep 2022 Nanyang Ye, Jingbiao Mei, Zhicheng Fang, Yuwen Zhang, Ziqing Zhang, Huaying Wu, Xiaoyao Liang

For neural architecture search space design, instead of conducting neural architecture search on the whole feasible neural architecture search space, we first systematically explore the weight drifting tolerance of different neural network components, such as dropout, normalization, number of layers, and activation functions in which dropout is found to be able to improve the neural network robustness to weight drifting.
