The Little Fish

This is a hobby project that explores how the intelligence of a neural network (i.e. a primitive brain) might be optimized (i.e. evolved) across generations without using back propagation and real-time feedback.
Detailed description can be found in this webpage: The Little Fish

Install:

>>> git clone https://github.com/zhuangjun1981/littlefish
>>> cd littlefish
>>> pip install .

Run simulation

• first edit the <repo directory>/littlefish/scripts/for_simulation/run_simulation_1.py
  • modify data_folder to be a directory for saving simulation logs (can be several Gigs)
  • if running from scratch, make sure start_generation_ind = 0
• Then run the script in python: python <repo directory>/littlefish/scripts/for_simulation/run_simulation_1.py

View simulation

• First start simulation viewer:

python <repo directory>/littlefish/viewer/simulation_viewer.py

• Click the Choose File button
• Pick any .hdf5 file saved in the simulation log folder.
