Zero-shot Concept Bottleneck Models

Shin'ya Yamaguchi, Kosuke Nishida, Daiki Chijiwa +1

Concept bottleneck models (CBMs) are inherently interpretable and intervenable neural network models, which explain their final label prediction by the intermediate prediction of h…

Parallel In-context Learning for Large Vision Language Models

Shin'ya Yamaguchi, Daiki Chijiwa, Tamao Sakao +1

Large vision-language models (LVLMs) employ multi-modal in-context learning (MM-ICL) to adapt to new tasks by leveraging demonstration examples. While increasing the number of demo…

Rationale-Enhanced Decoding for Multi-modal Chain-of-Thought

Shin'ya Yamaguchi, Kosuke Nishida, Daiki Chijiwa

Large vision-language models (LVLMs) have demonstrated remarkable capabilities by integrating pre-trained vision encoders with large language models (LLMs). Similar to single-modal…

Do We Really Need Permutations? Impact of Model Width on Linear Mode Connectivity

Akira Ito, Masanori Yamada, Daiki Chijiwa +1

Recently, Ainsworth et al. empirically demonstrated that, given two independently trained models, applying a parameter permutation that preserves the input-output behavior allows t…

Lossless Vocabulary Reduction for Auto-Regressive Language Models

Daiki Chijiwa, Taku Hasegawa, Kyosuke Nishida +4

Tokenization -- the process of decomposing a given text into a sequence of subwords called tokens -- is one of the key components in the development of language models. Particularl…

The Strong Lottery Ticket Hypothesis for Multi-Head Attention Mechanisms

Hikari Otsuka, Daiki Chijiwa, Yasuyuki Okoshi +3

The strong lottery ticket hypothesis (SLTH) conjectures that high-performing subnetworks, called strong lottery tickets (SLTs), are hidden in randomly initialized neural networks.…
