+# KoMiniLM
+🐣 Korean mini language model
+
+## Overview
+Current language models usually consist of hundreds of millions of parameters which brings challenges for fine-tuning and online serving in real-life applications due to latency and capacity constraints. In this project, we release a light weight korean language model to address the aforementioned shortcomings of existing language models.
+
+## Quick tour
+```python
+from transformers import AutoTokenizer, AutoModel
+
+tokenizer = AutoTokenizer.from_pretrained("BM-K/KoMiniLM") # 23M model
+model = AutoModel.from_pretrained("BM-K/KoMiniLM")
+
+inputs = tokenizer("안녕 세상아!", return_tensors="pt")
+outputs = model(**inputs)
+```
+
+## Update history
+** Updates on 2022.06.20 **
+- Release KoMiniLM-bert-68M
+
+** Updates on 2022.05.24 **
+- Release KoMiniLM-bert-23M
+
+## Pre-training
+`Teacher Model`: [KLUE-BERT(base)](https://github.com/KLUE-benchmark/KLUE)
+
+### Object
+Self-Attention Distribution and Self-Attention Value-Relation [[Wang et al., 2020]](https://arxiv.org/abs/2002.10957) were distilled from each discrete layer of the teacher model to the student model. Wang et al. distilled in the last layer of the transformer, but that was not the case in this project.
