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.

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

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

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 language nb.)
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.
