SPLASH-1B: Wake up for Touch! Mask-isolated Tactile Alignment Learning in MLLMs

This repository contains the SPLASH-1B model checkpoint presented in the paper Wake up for Touch! Mask-isolated Tactile Alignment Learning in MLLMs.

SPLASH-1B integrates tactile perception into vision-language models by using InternVL2.5-1B as the base MLLM backbone and a ViT-Tiny tactile frontend.

Description

SPLASH integrates tactile perception into vision-language models through a two-stage pipeline:

1. Dormant Mask Generation: Quantifies the significance of each pretrained parameter via weight & activation importance scoring on the LLM backbone, partitioning the parameter space into a dormant and critical subspace.
2. Mask-Guided Sparse Training: Updates the isolated dormant subspace to align tactile representations while freezing the critical subspace to safeguard established vision-language reasoning, preventing catastrophic forgetting.
