# 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](https://huggingface.co/papers/2607.00302).

SPLASH-1B integrates tactile perception into vision-language models by using [InternVL2.5-1B](https://huggingface.co/OpenGVLab/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.
