Spaun 1.0

Spaun is a biologically realistic model of cognition that is not only able to perform multiple (at least 10) cognitive, perceptual, and motor tasks, but also utilizes the same model parameters across all tasks. Spaun is able to perform tasks that encompass strictly visual tasks (e.g. recognition of handwritten digits), memory tasks (e.g. forward and backward recall of a list), simple cognitive tasks (e.g. counting), and complex fluid intelligence tasks (e.g. solving the Raven's Progressive Matrices).

Instructions

To run Spaun, follow these instructions:

1. Install Nengo 1403 as per the INSTALL-NENGO.txt file.
2. Run Nengo 1403.
3. Within Nengo, press CTRL+P to bring up the scripting console, and type run run_spaun_win.py (if you are on a Windows-based system) or run run_spaun_lin.py (if you are on a Linux/Unix-based system).
4. The log files that are generated can be found in spaun/out_data located within this directory.

Notes

• This model requires a machine with at least 24GB of RAM to run. Estimated run times for a quad-core 2.5GHz are 3 hours per 1 second of simulation time.
• See the run_spaun.py file in the spaun directory for experiment options.
• Model parameters can be altered in the conf.py file found in the spaun directory.
• To load the model with a different number of dimensions than the default (default = 512 dimensions), alter the line num_dim = 512 in the conf.py file. Setting the number to 4 enables the model to be loaded on a 2GB machine.
