Statistical models for neural data: from GLMs to latent variables (Part 1)
Statistical models for neural data: from GLMs to latent variables (Part 1)
Part 1 of 2 of a tutorial on statistical models for neural data
Topics covered in this lesson
- Introduction to the neural coding problem: how are stimuli and actions encoded in neural activity?
- What aspects of neural activity carry information?
- Regression models, latent variable models: aim to capture hidden structure underlying neural activity
- Model fitability/tractability vs richness and flexibility, finding a "sweet spot" in between
