When calculating specificity in the shapeworks studio how many random shape samples are generated across the modes of variation to compare with training shapes. Is it a default value, based on the number of training shapes or until the mean value platau’s?
Hope this makes sense
It looks like the specificity computation is currently hard-coded to 1000 samples:
double ShapeEvaluation::compute_specificity(const ParticleSystemEvaluation& particle_system, const int num_modes,
const std::string& save_to, bool surface_distance_mode) {
const long n = particle_system.num_samples();
const long d = particle_system.num_dims();
int num_values = particle_system.get_num_values_per_particle();
auto meshes = particle_system.get_meshes();
if (num_modes > n - 1) {
throw std::invalid_argument("Invalid mode of variation specified");
}
const int num_samples = 1000;
// Keep track of the reconstructions so we can visualize them later
std::vector<Reconstruction> reconstructions;
Eigen::VectorXd mean_specificity(num_modes);
Eigen::VectorXd std_specificity(num_modes);
Eigen::MatrixXd spec_store(num_modes, 4);
// PCA calculations
const Eigen::MatrixXd& pts_models = particle_system.get_matrix();
