Filters API

Filters API#

Introduction#

In eprllib, Filters are used to process an agent’s observations before they are used for decision-making. They provide a mechanism to modify or transform the raw observations, allowing for more robust and efficient agent behavior. This document provides a detailed explanation of the Filters API in eprllib.

Relationship with ObservationSpec#

Filters operate on the observations defined in ObservationSpec. The order of operations is as follows:

  1. Observations are gathered: The agent’s observations are collected from the environment based on the configuration in ObservationSpec.

  2. Observations are filtered: The raw observations are passed to the filter function defined in FilterSpec.

  3. Filtered observations are used: The filtered observations are then used by the agent for decision-making.

Defining custom Filter functions#

Here’s a complete example of how to define and use filters:
