Metrics

For correct work metrics require specific representation format. (e. g. map expects detection annotation and detection prediction for evaluation).

In case when you use complicated representation located in representation container, you need to add options `annotation_source`

and `prediction_source`

in configuration file to select specific representation, another way metric calculation possible only if container has only one suitable representation and will be resolved automatically. `annotation_source`

and `prediction_source`

should contain only one annotation identifier and output layer name respectively. You may optionally provide `reference`

field for metric, if you want calculated metric tested against specific value (i.e. reported in canonical paper) and acceptable `threshold`

for metric deviation from reference value.

Every metric has parameters available for configuration.

Accuracy Checker supports providing detailed information necessary for understanding metric calculation for each data object. This feature can be useful for debug purposes. For enabling this behaviour you need to provide `--profile True`

in accuracy checker command line. Additionally, you can specify directory for saving profiling results `--profiler_logs_dir`

and select data format in `--profile_report_type`

between `csv`

(brief) and `json`

(more detailed).
