Evaluating Models — FiftyOne documentation

Like VOCstyle evaluation, only one IoU (default = ) is used to calculate mAP. You can customize this value via the iou parameter. When dealing with crowd objects, Open Imagesstyle evaluation dictates that if a crowd is matched with multiple predictions, each counts as one true positive when computing mAP. When you specify an eval_key parameter, a number of helpful fields will be populated ...

VOC

Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure at ordinary room temperature. Their high vapor pressure results from a low boiling point, which causes large numbers of molecules to evaporate or sublimate from the liquid or solid form of the compound and enter the surrounding air, a trait known as volatility. For example, formaldehyde, which evaporates ...
