Public Member Functions

int init (const MedFeatures &medf, TQRF_Params &params)
 
- Public Member Functions inherited from SerializableObject
virtual int version () const
 Relevant for serializations.
 
virtual string my_class_name () const
 For better handling of serializations it is highly recommended that each SerializableObject inheriting class will implement the next method.
 
virtual void serialized_fields_name (vector< string > &field_names) const
 The names of the serialized fields.
 
virtual void * new_polymorphic (string derived_name)
 for polymorphic classes that want to be able to serialize/deserialize a pointer * to the derived class given its type one needs to implement this function to return a new to the derived class given its type (as in my_type)
 
virtual void pre_serialization ()
 
virtual void post_deserialization ()
 
virtual size_t get_size ()
 Gets bytes sizes for serializations.
 
virtual size_t serialize (unsigned char *blob)
 Serialiazing object to blob memory. return number ob bytes wrote to memory.
 
virtual size_t deserialize (unsigned char *blob)
 Deserialiazing blob to object. returns number of bytes read.
 
size_t serialize_vec (vector< unsigned char > &blob)
 
size_t deserialize_vec (vector< unsigned char > &blob)
 
virtual size_t serialize (vector< unsigned char > &blob)
 
virtual size_t deserialize (vector< unsigned char > &blob)
 
virtual int read_from_file (const string &fname)
 read and deserialize model
 
virtual int write_to_file (const string &fname)
 serialize model and write to file
 
virtual int read_from_file_unsafe (const string &fname)
 read and deserialize model without checking version number - unsafe read
 
int init_from_string (string init_string)
 Init from string.
 
int init_params_from_file (string init_file)
 
int init_param_from_file (string file_str, string &param)
 
virtual int init (map< string, string > &map)
 Virtual to init object from parsed fields.
 
int update_from_string (const string &init_string)
 
virtual int update (map< string, string > &map)
 Virtual to update object from parsed fields.
 
virtual string object_json () const
 

Data Fields

vector< vector< short > > qx
 
vector< vector< float > > q_to_val
 a vector of features that mimics the input x_in features matrix, but coded into quantized values
 
const MedFeaturesorig_medf
 from a q value to float value : q=0 is reserved for missing value the range for q>0 is : [q_to_val[q], q_to_val[q+1])
 
int nfeat = 0
 pointer to the original MedFeatures
 
vector< string > feature_names
 just an easy helper that = qx.size()
 
int ncateg = 0
 useful for debugging
 
vector< const vector< float > * > orig_data
 ncateg 0 is regression, otherwise categories are assumed to be 0 ... ncateg-1
 
vector< string > feat_names
 pointers to the original data given
 
vector< float > y
 as given in train
 
vector< int > y_i
 
vector< int > last_time_slice
 
int n_time_slices
 when there's more than 1 time slice there may be censoring involved and the last_time_slice is the last uncensored one.
 
vector< int > slice_counts [2]
 1 time slice is simply the regular case of a label for the whole future
 
vector< vector< int > > lists
 counts of elements in slices (in case of non regression trees). slices with no variability are not interesting.
 
vector< int > is_categorial_feat
 lists[0] is always the lines used for training the trees in round 1 the others can be used for later stages, for example : lists[1] could be used for early stopping measurements or for estimating weights for trees/nodes
 
vector< vector< vector< int > > > time_categ_pids
 
vector< vector< vector< int > > > time_categ_idx
 
vector< vector< int > > categ_pids
 
vector< vector< int > > categ_idx
 
unordered_map< int, vector< vector< vector< int > > > > pid2time_categ_idx
 
vector< float > wgts
 
vector< float > orig_wgts
 
vector< float > probs
 
vector< float > w_to_sum
 
vector< vector< float > > sum_over_trees
 
float alpha0
