TODO list

Generic

• reporting callback
  • provide train_data for train_on_file (currently always null)
  • there is a possible memory leak if the callback return allocated value (e.g. string)
    • convert_to_bool is used without freeing previous data
  • proper testing (more iterations)
• error logging
  • use log error messages when generic error is reported (fann_read_train_from_file)
    • static variable (fann_default_error_log) in fannlib - TSRM problem
  • use error log (fann_set_error_log) for all error messages including messages from this extension
  • test if fannlib logging works (messages generated by fannlib are writtend to the file)
• check parameters ranges and over/underflows
  • supplied longs fits to the unsigned int in fann_create_train_from_callback
  • valid contants
  • FANN connection_rate param for create_sparse*
  • check int intervals for fann_train_on_fail
• compare PHP outputs with C outputs in all examples

Functions - implementation

• fann_print_connections - either rewrite or redirect output
• fann_print_parameters - either rewrite or redirect output

Functions - tests

• fann_init_weights - train_data test must be done first
