# MachineLearningLM

This repository contains the model presented in the paper [MachineLearningLM: Scaling Many-shot In-context Learning via Continued Pretraining](https://huggingface.co/papers/2509.06806).

## Model Summary

Can LLMs learn from 1,000 in-context examples?

Introducing **MachineLearningLM** 🧪📊 — a model continuously pretrained on millions of synthetic tabular ML tasks, enabling robust many-shot in-context learning.

📈 **Scales from 8 to 1,024 examples**

📈 ​**​~15% improvement​**​ on unseen tabular tasks compared to o3-mini / GPT-5-mini / Qwen-2.5-7B-Instruct

🌲 ​**​Random-Forest–level numerical modeling robustness​**​
 
🧠 ​**​MMLU score: 75.4%​**​

## Evaluation and Validation

We have developed an automated evaluation framework — simply configure the parameters to easily perform validation and evaluation. 
**The code is now open-sourced at our [GitHub repository](https://github.com/HaoAreYuDong/MachineLearningLM).**

**Quick Start**

```bash
pip install -r requirements.txt
python ./src/evaluation/model_pred/dl_model_pred.py \
  --input_dir ./demo_input.jsonl \
  --output_dir ./demo_output.jsonl \
  --model_name MachineLearningLM/MachineLearningLM-7B-v1
```
**Pipeline**
```bash
# modify the evaluate_parameters.sh file
source evaluate_parameters.sh

# Option 1  End-to-End Pipeline
./scripts/evaluate_pipeline.sh

# Option 2  Parallel Processing
./scripts/multi_process/data_prep.sh
./scripts/multi_process/prompt_gen.sh  # For deep learning only
./scripts/multi_process/model_pred.sh
./scripts/multi_process/evaluation.sh
./scripts/multi_process/report.sh

# Option3   Sequential Processing
./scripts/single_process/data_prep.sh
./scripts/single_process/prompt_gen.sh  # For deep learning only
./scripts/single_process/model_pred.sh
./scripts/single_process/evaluation.sh
./scripts/single_process/report.sh
```

## Tabicl Evaluation

**This part of the code needs to run in an environment with the tabicl and openpyxl libraries installed.**

The evaluation code for tabicl is placed separately in the `./src/evaluation/tabicl_evaluate.py` file. Use `./scripts/tabicl_evaluate.sh` to obtain the evaluation results for tabicl.

Use --datasets to specify the datasets to be evaluated, and --sample_sizes to indicate the number of shots. 

If multiple datasets need to be evaluated, separate them with spaces. To evaluate all CSV files in the input folder, use **all**.

## Prior_data

MachineLearningLM uses the code from tabicl to generate prior data.

Use `./scripts/generate_data.sh` to generate the prior data. It generates the corresponding .pt and .csv files, and normalizes the feature values in the CSV files to the range of 0–999, as we did in the paper.

## Train

MachineLearningLM uses the LLaMA-Factory framework for training.

#### Training Environment Configuration

```bash
cd ./third_party/LLaMA-Factory
pip install -e ".[torch,metrics]" --no-build-isolation
pip install wandb
```

Use `./scripts/train.sh` for training.
