The Auto Tune Models (ATM) project, developed by the Data to AI Lab at MIT, is designed to simplify the process of building machine learning models. With ATM, you provide your dataset in CSV format, and it will automatically attempt to construct the best predictive model. In this article, we’ll walk you through the installation process, how to use ATM, and what to do if you encounter any issues.

Getting Started with ATM

Before diving into using ATM, let’s get it up and running on your machine. First, ensure you have the necessary requirements and set up a virtual environment.

Installation Requirements

• Python 2.7, 3.5, or 3.6
• Virtualenv (optional but recommended)

Setting Up Virtual Environment

To avoid any conflicts with existing installations, it’s a good idea to create a virtual environment. Here are the commands you need:

pip install virtualenv
virtualenv -p $(which python3.6) atm-venv
source atm-venv/bin/activate

Remember, you need to activate this environment every time you start a new console session for ATM.

Installing ATM

You can install ATM using pip after activating your virtual environment:

pip install atm

Alternatively, you can install it from the source by cloning its repository:

git clone git@github.com:HDI-Project/ATM.git
cd ATM
git checkout stable
make install

Using ATM: A Quickstart Guide

Now that you have ATM installed, let’s quickly go through the steps to use it effectively.

1. Get the Demo Data

To start, download a demo dataset (e.g., pollution data) which you will use with ATM:

atm download_demo pollution_1.csv

2. Create an ATM Instance

Once you have the CSV file, create an instance of ATM:

from atm import ATM
atm = ATM()

This will create an SQLite database in your current directory.

3. Search for the Best Model

Now it’s time to find the best model for your target variable:

results = atm.run(train_path='pollution_1.csv')

You can also provide a URL or an S3 Bucket path for your dataset.

4. Explore the Results

After running the model search, you can explore your results in several ways:

• To get a summary of the data run, use: results.describe()
• For information about the best classifier, use: results.get_best_classifier()
• To view scores for all classifiers tested, use: results.get_scores()

5. Make Predictions

Once you’ve identified and explored your best classifier, you can save it using the following command:

results.export_best_classifier('pathtomodel.pkl')

You can then load this model for future predictions.

from atm import Model
model = Model.load('pathtomodel.pkl')

Troubleshooting

If you encounter any issues while using ATM, here are a few troubleshooting tips:

• Ensure your Python version is compatible—preferably using 3.6 or newer.
• Check that your CSV file is formatted correctly with the first row as headers, a single comma as the separator, and includes a target variable.
• Make sure your virtual environment is activated before running commands.
