| virtual void clsfy_builder_1d::b_read | ( | vsl_b_istream & | bfs | ) | [pure virtual] |
Load class from binary file stream.
Implemented in clsfy_binary_threshold_1d_builder, clsfy_mean_square_1d_builder, and clsfy_binary_threshold_1d_gini_builder.
| virtual void clsfy_builder_1d::b_write | ( | vsl_b_ostream & | bfs | ) | const [pure virtual] |
Save class to binary file stream.
Implemented in clsfy_binary_threshold_1d_builder, clsfy_mean_square_1d_builder, and clsfy_binary_threshold_1d_gini_builder.

| ) | const [pure virtual] |
Build a binary_threshold classifier.
Train classifier, returning weighted error Selects parameters of classifier which best separate examples from two classes, weighting examples appropriately when estimating the misclassification rate. Returns weighted sum of error, e.wts, where e_i =0 for correct classifications, e_i=1 for incorrect.
Implemented in clsfy_binary_threshold_1d_builder, and clsfy_mean_square_1d_builder.

| ) | const [pure virtual] |
Train classifier, returning weighted error.
Selects parameters of classifier which best separate examples, weighting examples appropriately when estimating the misclassification rate. data[i] is a triple, {value,class_number,weight} Returns weighted sum of error. Note that input "data" must be sorted to use this routine
Implemented in clsfy_binary_threshold_1d_builder, and clsfy_mean_square_1d_builder.
| virtual clsfy_builder_1d* clsfy_builder_1d::clone | ( | ) | const [pure virtual] |

| void clsfy_builder_1d::config | ( | vcl_istream & | as | ) | [virtual] |
Initialise the parameters from a text stream.
Default case accepts no parameters.

| vcl_auto_ptr< clsfy_builder_1d > clsfy_builder_1d::new_builder | ( | vcl_istream & | as | ) | [static] |
Load description from a text stream.
The stream should contain the name of the feature extractor class that will be used, followed by a brace-enclosed list of parameters for the builder. This function will construct the appropriate clsfy_builder_1d derivative and return that.
- Exceptions:
-
if the parse fails.
