Submitted by Judy Hanning on Sat, 2016-07-23 17:02

One can define what type of dyslexia a person has by analyzing errors in reading.

In the video, a presentation of the Latent Dirichlet Allocation model is provided.

  • It is explained in detail.
  • Shows how to diagnose dyslexia.
  • Tests and experiments are also provided.
Reading is a very complex process involving multiple areas in the brain and so is dyslexia - Yair Lakretz

Key Takeaways:

1
The presented study tried to find out if graphical models can diagnose dyslexia similar to how experts do. And which model can best capture the hidden structure of reading errors.
2
The Dual-Route Reading Model is a cognitive model that tries to explain the complexities of reading errors in dyslexia. Two types of dyslexia mentioned: Letter Position Dyslexia (LPD) and Surface Dyslexia (type 1).
3
The researcher used the Latent Dirichlet Allocation (LDA) Model to analyze reading responses of their subjects. Based on the findings, this model could help in the understanding of dyslexia and improving the screening tests.
