Unsupervised Discovery of Student Strategies

Benjamin Shih, Kenneth R. Koedinger, Richard Scheines
2010 Educational Data Mining  
Unsupervised learning algorithms can discover models of student behavior without any initial work by domain experts, but they also tend to produce complicated, uninterpretable models that may not predict  ...  student learning.  ...  Stepwise-HMM-Cluster serves two goals at once: it tries to build a collection of HMMs to fit the observed sequences of actions, but also requires that the collection predict student learning gain.  ...

Combining Self-Supervised Learning and Imitation for Vision-Based Rope Manipulation [article]

Ashvin Nair, Dian Chen, Pulkit Agrawal, Phillip Isola, Pieter Abbeel, Jitendra Malik, Sergey Levine
2017 arXiv   pre-print
We present a learning-based system where a robot takes as input a sequence of images of a human manipulating a rope from an initial to goal configuration, and outputs a sequence of actions that can reproduce  ...  To perform this task, the robot learns a pixel-level inverse dynamics model of rope manipulation directly from images in a self-supervised manner, using about 60K interactions with the rope collected autonomously  ...  One of the key challenges in self-supervised robot learning is collecting enough data for learning skilled behaviors, since the state and action space for practical manipulation tasks is extremely large  ...
