About Me

Marcos Manuel Muraro is the author of Jano.

The project grew out of a practical need: evaluating systems whose behavior changes across time requires more than a random split. Jano is meant to make those simulations explicit, inspectable and easier to communicate.

Project direction

Jano is currently focused on:

  • clear temporal partition definitions,

  • support for pandas, NumPy and Polars inputs,

  • efficient splitting for larger datasets,

  • simulation reporting that is useful before model training begins.
