The hardest data science tournament in the world.

Predict the stock market.

The hardest data science tournament in the world.

Predict the stock market.

Start with hedge fund quality data.

It is clean and regularized, designed to be usable right away. Obfuscated, so it can be given out for free.

Each id corresponds to a stock at a specific time era. The features describe the various quantitative attributes of the stock at the time. The target represents an abstract measure of performance a fixed number of weeks into the future.

Apply machine learning to predict the stock market.

Build a model using the example Python and R scripts. Everything you need to get started in one package.

#!/usr/bin/env python
""" Example classifier on Numerai data using a xgboost regression. """

import pandas as pd
from xgboost import XGBRegressor

# training data contains features and targets
training_data = pd.read_csv("numerai_training_data.csv").set_index("id")

# tournament data contains features only
tournament_data = pd.read_csv("numerai_tournament_data.csv").set_index("id")
feature_names = [f for f in training_data.columns if "feature" in f]

# train a model to make predictions on tournament data
model = XGBRegressor(max_depth=5, learning_rate=0.01, \
                   n_estimators=2000, colsample_bytree=0.1)[feature_names], training_data["target"])

# submit predictions to
predictions = model.predict(tournament_data[feature_names])
