BriCA Platform
The BriCA Platform is a collection of software modules to develop brain-inspired cognitive architecture with BriCA and to be run on OpenAI Gym.
Modules
BriCA Platform contains the following modules:
- BriCA1: the BriCA core to describe and run brain-inspired cognitive architectures (in Python).
- brica_gym: a Python program to create OpenAI Gym agents
(containing classes for adapting to Gym execution cycles) - BriCAL: interpreter that generates code from BriCA Language description
- bif_excel2brical: utility to generate BriCA Language files from spreadsheet (Excel) files
Use Case
Cognitive architecture development with the BriCA Platform could proceed in the following order:
- Describe modules, ports, and connections in a spreadsheet (Excel file)
（See bif_excel2brical and the examples below for the format.) - Convert the spreadsheet into the JSON format with bif_excel2brical
- Implement a Gym environment, BriCA components, and the main program (see the examples below).
- Test & debug
Main Program Overview
Code for cognitive architecture with the BriCA language interpreter and OpenAI Gym generally contains the following:
- Importing necessary libraries (including
brica1,brica1.brica_gym,brica1,brical,gym,numpy,json) - Reading and checking a BriCA language file (JSON)
(At this stage, BriCA modules are generated and linked to an internal expression of the languagenb.) - Reading other config. files (if any)
- Instantiating a Gym environment (
env) - Initializing BriCA components
- Creating ports（
nb.make_ports()） agent_builder = brical.AgentBuilder()agent = agent_builder.create_gym_agent(nb, the top module, env)scheduler = brica1.VirtualTimeSyncScheduler(agent)- Executing “scheduler.step()'' while looping
(Note that tokens are circulated to synchronize with Gym env. cycles.) - Closing
See examples below for details.
