Enumeration Type Documentation

◆ ntact_function_id_t

enum ntact_function_id_t

Enumeration of supported activation functions.

This enumeration defines identifiers for the activation functions implemented in the NeuroTIC framework.
Each identifier corresponds to a specific activation function and its derivative, which are stored in the ntact_activation dispatch table.
The NTACT_TOTAL_FUNCTIONS entry is used to indicate the total number of activation functions available, which is useful for iterating over the dispatch table and for validating activation function identifiers.
Additional activation functions can be added to this enumeration as needed, along with their corresponding implementations in the ntact_activation dispatch table and appropriate entries in the ntact_rand_range for weight initialization.

Enumerator
NTACT_BOOLEAN	Boolean step activation function.
NTACT_SIGMOID	Sigmoid activation function.
NTACT_TOTAL_FUNCTIONS	Total number of activation functions.

Variable Documentation

◆ ntact_activation

float(* ntact_activation[NTACT_TOTAL_FUNCTIONS][2])(float) ( float )

extern

Activation function and derivative dispatch tables.

See also: ntact_function_id_t for function identifiers.

Defines the mapping between activation identifiers and their associated execution functions.
Indexing:

First index : activation identifier
Second index : [0] activation [1] derivative

The table is initialized with the supported activation functions, and can be extended to include additional functions as needed.

◆ ntact_rand_range

float ntact_rand_range[NTACT_TOTAL_FUNCTIONS][2]

extern

Random initialization range table for activation functions.

Returns: ntact_rand_range A 2D array where each row corresponds to an activation function, with the first column representing the minimum value and the second column representing the maximum value for weight initialization.
These ranges are used in the randnet function to ensure that weights are initialized within appropriate bounds for each activation function, which can help improve training performance and convergence.
