This lesson introduces methods for dimensionality reduction of data, with focus on factor analysis.

Topics covered in this lesson
  • Large noisy multi-channel datasets from new methods of large scale neural recording
  • Covariation among channels
  • Binning and resolution
  • Dimensionality reduction
  • Denoising
  • Dimensionality reduction models: principal component analysis (PCA), factor analysis (FA), Gaussian-process factor analysis (GPFA), latent dynamical systems, non-linear systems
  • Explicit noise models
  • Closer explanation of factor analysis, with computations
Prerequisites
  • Linear algebra (matrices)
  • Some basic statistics (probability and conditional probability)
