(Inverse) optimal control for linear quadratic Gaussian systems
Project description
Inverse optimal control for continuous psychophysics
This repository contains the official implementation of the inverse optimal control method presented in the paper:
Straub, D., & Rothkopf, C. A. (2021). Putting perception into action: Inverse optimal control for continuous psychophysics. bioRxiv.
Installation
The package can be installed via pip
python -m pip install lqg
although I recommend cloning the repository to get the most recent version and installing locally with a virtual environment
python -m venv env
source env/bin/activate
python -m pip install -e .
Usage examples
-
main.py
shows how to simulate data and infer parameters using the LQG model of the tracking task. -
notebooks/01-HowTo.ipynb
explains the model and its parameters in more detail, including the extension to subjective internal models. -
notebooks/02-Data.ipynb
fits the ideal observer and subjective actor model to the data from Bonnen et al. (2015) to reproduce Fig. 4A from our paper.
