 # CultureMERT: Continual Pre-Training for Cross-Cultural Music Representation Learning
 📑 [**Read the full paper (to be presented at ISMIR 2025)**](...TODO)
 
-**CultureMERT-TA-95M** is a 95M-parameter music foundation model adapted to diverse musical cultures through **task arithmetic**. Instead of direct continual pre-training on a multi-cultural mixture, as in [CultureMERT-95M](https://huggingface.co/ntua-slp/CultureMERT-95M), this model merges multiple **single-culture adapted** variants of [MERT-v1-95M](https://huggingface.co/m-a-p/MERT-v1-95M)—each continually pre-trained via our two-stage strategy on a distinct musical tradition:
