GeoSteer: Faithful Chain-of-Thought Steering via Latent Manifold Gradients
Kentaro Kazama, Daiki Shirafuji, Tatsuhiko Saito
Recent advances in Large Language Models (LLMs) have demonstrated remarkable progress in their reasoning capabilities, such as Chain-of-Thought (CoT). Most approaches rely on CoT r…
An Empirical Survey of Model Merging Algorithms for Social Bias Mitigation
Daiki Shirafuji, Tatsuhiko Saito, Yasutomo Kimura
Large language models (LLMs) are known to inherit and even amplify societal biases present in their pre-training corpora, threatening fairness and social trust. To address this iss…
Bridging the Modality Gap by Similarity Standardization with Pseudo-Positive Samples
Shuhei Yamashita, Daiki Shirafuji, Tatsuhiko Saito
Advances in vision-language models (VLMs) have enabled effective cross-modality retrieval. However, when both text and images exist in the database, similarity scores would differ…
A Hybrid Search for Complex Table Question Answering in Securities Report
Daiki Shirafuji, Koji Tanaka, Tatsuhiko Saito
Recently, Large Language Models (LLMs) are gaining increased attention in the domain of Table Question Answering (TQA), particularly for extracting information from tables in docum…
