Time-Varying Learning and Content Analytics via Sparse Factor Analysis
Andrew S. Lan
Video in druga učna gradiva
Oznake: computer science;data mining;knowledge extraction
We propose SPARFA-Trace, a new machine learning-based framework for time-varying learning and content analytics for educational applications. We develop a novel message passing-based, blind, approximate Kalman filter for sparse factor analysis (SPARFA) that jointly traces learner concept knowledge o ...

Mining Commonsense Knowledge From Personal Stories in Internet Weblogs
Andrew S. Gordon
Video in druga učna gradiva
Oznake: computer science;information extraction
Recent advances in automated knowledge base construction have created new opportunities to address one of the hardest challenges in Artificial Intelligence: automated commonsense reasoning. In this paper, we describe our recent efforts in mining commonsense knowledge from the personal stories that p ...

MCMC schemes for partially observed diffusions - Some recent advances
Andrew Golightly
Video in druga učna gradiva
Oznake:
It is well known that likelihood inference for arbitrary nonlinear diffusion processes observed at discrete times is problematic since closed form transition densities are rarely tractable. One widely used solution involves the introduction of latent data points between every pair of observations to ...

Plasticity at the Brain-Computer Interface
Andrew Jackson
Video in druga učna gradiva
Oznake: technology;neurotechnology
Next generation recurrent Brain-Computer Interfaces will not only extract signals from cortical activity but also deliver feedback to the nervous system via electrical stimulation. For example, stimulation of cervical spinal segments can produce functional arm and hand movements such as reaching and ...
