+# Common Starcoder dataset
+
+This dataset is generated from [bigcode/starcoderdata](https://huggingface.co/datasets/bigcode/starcoderdata).
+
+## Generation Process
+1. We filtered the original dataset with common language: C, Cpp, Java, Python and JSON.
+2. We removed some columns for mixing up with other dataset: "id", "max_stars_repo_path", "max_stars_repo_name"
+3. After removing the irrelevant fields, we shuffle the dataset with random seed=42.
+4. We filtered the data on "max_stars_count" > 300 and shuffle again.
+5. We further reduced the dataset size by select(range(current_size, 2_500_000)), However there are only 2.13M samples left.
+6. Add "n_tokens" by using GPT2Tokenizer to count the tokens in the "content" field.
