- A random number generator instance to define the state of the
- random permutations generator. If an integer is given, it fixes the
- seed. Defaults to the global numpy random number generator.
+ Determines random number generation for:
+
+ - Gibbs sampling from visible and hidden layers.
+
+ - Initializing components, sampling from layers during fit.
+
+ - Corrupting the data when scoring samples.
+
+ Pass an int for reproducible results across multiple function calls.
