Improve Language Model and Brain Alignment via Associative Memory (2025.findings-acl)
Copied to clipboard
| Challenge: | Existing studies have shown that associative memory is essential for language comprehension and comprehension. |
| Approach: | They propose to integrate associative memory into language models to improve alignment . they find alignment is improved in brain regions closely related to associativ memory processing . |
| Outcome: | The proposed model improves in brain regions closely related to associative memory processing. |
Language Reconstruction with Brain Predictive Coding from fMRI Data (2026.acl-long)
Copied to clipboard
| Challenge: | Existing studies have shown that the perception of speech can be decoded from brain signals and subsequently reconstructed as continuous language. |
| Approach: | They propose to use FMRI-to-text decoding with Predictive coding to generate a main network and a side network to generate brain predictive representations from related regions of interest. |
| Outcome: | The proposed model outperforms current decoding models on several evaluation metrics on two naturalistic language comprehension fMRI datasets. |
Rethinking Cross-Subject Data Splitting for Brain-to-Text Decoding (2025.emnlp-main)
Copied to clipboard
| Challenge: | Recent studies have successfully decoded natural language from non-invasive brain signals . current dataset splitting methods suffer from data leakage problem . |
| Approach: | They propose a right cross-subject data splitting criterion without data leakage for decoding fMRI and EEG signal to text. |
| Outcome: | The proposed method overfits and overestimates brain-to-text decoding models. |
Decoding the Echoes of Vision from fMRI: Memory Disentangling for Past Semantic Information (2024.emnlp-main)
Copied to clipboard
| Challenge: | Experimental results demonstrate that this method effectively disentangles the information within fMRI signals. |
| Approach: | They propose a task Memory Disentangling which extracts and decodes past information from fMRI signals. |
| Outcome: | The proposed method extracts and decodes past information from fMRI signals. |
