1. Motivation
1. The cocktail party problem
2. Definition -- matrices and data
3. Ambiguities
4. Illustration
2. What is independence?
1. Central limit theorm
2. Nongaussian is independent
3. Estimators of nongaussianity
1. Kurtosis
2. Negentropy
3. Others
3. Preprocessing for ICA
1. Centering
2. Whitening
3. PCA
4. Fast ICA
5. Neuroscience Applications
1. EEG
2. Imaging
