(Inverse) optimal control for linear quadratic Gaussian systems

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 -r requirements.txt
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.
