Field Documentation

double** Som::connectivity

custom connectivity matrix that can implement an arbitrary topology for the SOM-network

Definition at line 144 of file som.h.

SOMConnectivityType Som::connectivity_type

giving the dimension/structure of the SOM

Definition at line 143 of file som.h.

int Som::dimension

dimension of code-book vector (corresponds to data-dimensionality)

Definition at line 130 of file som.h.

VectorDistanceFunction Som::distancefct

distance measure between data and codebook-vectors

Definition at line 132 of file som.h.

void* Som::distancefct_parameters

optional; pointer to parameters for some of the VectorDistanceFunction s

Definition at line 133 of file som.h.

int Som::initial_runs

number of runs with large flexibility (ordering phase) after which it is more restricted; e.g. 0.1*nruns

Definition at line 137 of file som.h.

double** Som::m

code-book vectors

Definition at line 129 of file som.h.

int Som::n

how many code-book vectors?

Definition at line 131 of file som.h.

NeighbourhoodFunction Som::neighbourhoodfct

neighbourhood function

Definition at line 140 of file som.h.

int Som::nruns

number of runs to convergence

Definition at line 136 of file som.h.

ProgressBarFunction Som::progress

Definition at line 150 of file som.h.

gsl_rng_type* Som::random_number_type

GSL-random number generator type

Definition at line 147 of file som.h.

gsl_rng* Som::rng

the GSL random number generator

Definition at line 148 of file som.h.

TimeDecayFunction Som::time_decay

function giving the decay of the learning rate

Definition at line 141 of file som.h.
