Winter semester 2019/20

We offer the Master level lecture Methods for human motion modeling and capturing (KIS entry).

Fridays, 11:45 - 13:15, room 48-210

Description

In this lecture you learn how to deduce biomechanically interpretable movement data from sensor measurements (in particular body-worn inertial measurement units). The focus of the lecture will be on models and methods from sensor fusion (recursive and optimization based), system identification and machine learning. The needed basics in human anatomy will also be provided. In hands-on sessions you will get the opportunity to apply the learnt methods to real data captured in our motion lab.

The lecture addresses master level students of computer science and applied mathematics.

Topics

The available topics will focus on human motion simulation / behavior imitation learning

Example references:

  • Generative Adversarial Imitation Learning (GAIL): paper, code base
  • Learning human behaviors from motion capture by adversarial imitation: paper, code base

For students, who are interested in starting a master thesis in this area (e.g. after a seminar/project):

  • InfoGAIL: Interpretable Imitation Learning from Visual Demonstration: paper, code base

The idea is to apply the presented techniques to our own motion capture databases (walking of healthy people and patients) for automatically identifying different movement patterns (physiological gait, limping), for being able to sample motion patterns (data augmentation) or for matching to known gait patterns.

All code bases use Tensorflow for the machine learning part.
