+# Introduction to our series work
+
+The development log of our Music Audio Pre-training (m-a-p) model family:
+- 17/03/2023: we release two advanced music understanding models, [MERT-v1-95M](https://huggingface.co/m-a-p/MERT-v1-95M) and [MERT-v1-330M](https://huggingface.co/m-a-p/MERT-v1-330M) , trained with new paradigm and dataset. They outperform the previous models and can better generalize to more tasks.
+- 14/03/2023: we retrained the MERT-v0 model with open-source-only music dataset [MERT-v0-public](https://huggingface.co/m-a-p/MERT-v0-public)
+- 29/12/2022: a music understanding model [MERT-v0](https://huggingface.co/m-a-p/MERT-v0) trained with **MLM** paradigm, which performs better at downstream tasks.
+- 29/10/2022: a pre-trained MIR model [music2vec](https://huggingface.co/m-a-p/music2vec-v1) trained with **BYOL** paradigm.

+
+## Explanation
+
+The m-a-p models share the similar model architecture and the most distinguished difference is the paradigm in used pre-training. Other than that, there are several nuance technical configuration needs to know before using:
+
+- **Model Size**: the number of parameters that would be loaded to memory. Please select the appropriate size fitting your hardware.
+- **Transformer Layer-Dimension**: The number of transformer layers and the corresponding feature dimensions can be outputted from our model. This is marked out because features extracted by **different layers could have various performance depending on tasks**.
+- **Feature Rate**: Given a 1-second audio input, the number of features output by the model.
+- **Sample Rate**: The frequency of audio that the model is trained with.
+
+
+# Introduction to MERT-v0-public
+
+**MERT-v0-public** is a completely unsupervised model trained on **completely non-comercial open-source** [Music4All](https://sites.google.com/view/contact4music4all) dataset and the part of [FMA_full](https://github.com/mdeff/fma) dataset that does not include tag "experimental".
+
+
+The training settings and model usage of MERT-v0-public can be referred to the [MERT-v0 model](https://huggingface.co/m-a-p/MERT-v0).
+
+Details are reported at the short article *Large-Scale Pretrained Model for Self-Supervised Music Audio Representation Learning*.
