Property Value

The contrast function determines how non-Gaussianity is measured during component extraction:

• LogCosh: Robust, general-purpose function. Good for most data types including sub-Gaussian and super-Gaussian sources. This is the default and recommended choice for most applications.
• Exponential: Optimized for super-Gaussian (heavily-tailed) distributions. Use when sources are known to have high kurtosis or extreme outliers.
• Cubic: Simple polynomial function. Works well for sub-Gaussian (light-tailed) distributions. Fastest but least robust to outliers.

The LogCoshAlpha parameter controls the behavior of the LogCosh function.

The default value is LogCosh.
