v2.1 Dataset — Numerai Signals

The "Alpha" dataset was released in July 2025.

train.parquet

Data used to train your model

train_neutralizer.parquet

Neutralization matrix for training eras. Signals Alpha and MPC use this matrix to neutralize your signal. Useful for training a model that is neutralization-aware.

train_sample_weights.parquet

Sample weights vector for training eras. Signals Alpha and MPC use sample weights to weight your signal after neutralization. Useful for training a model that is sample-weight-aware.

validation.parquet

Data used to validate or train your model.Expands every week to include data for the most recent eras with targets available.

validation_neutralizer.parquet

Neutralization matrix for validation eras. Signals Alpha and MPC use neutralize your signal using this matrix. Useful for calculating Alpha over the validation set.

validation_sample_weights.parquet

Sample weights vector for validation eras. Signals Alpha and MPC use sample weights to weight your signal after neutralization. Useful for calculating Alpha over the validation set.

validation_example_preds.parquet

An example file with predictions on the validation.parquet file. Allows you to easily try diagnostics.

live.parquet

The live data that your model predicts on. This changes daily.

live_neutralizer.parquet

Neutralization matrix for live data. Signals Alpha and MPC use this matrix to neutralize your signal.

live_sample_weights.parquet

Sample weights vector for live data. Signals Alpha and MPC use these weights to weight your signal after neutralization.

live_example_preds.parquet

An example file with predictions on the live.parquet file. Allows you to easily try your first submission.
