Performance Metrics

Accuracy (A)

A = (Number of Correct Predictions) / (Total Number of Predictions)

Accuracy measures the overall correctness of the algorithm’s predictions.

Precision (P)

P = (True Positives) / (True Positives + False Positives)

It quantifies the algorithm’s ability not to label false positives. It measures the fraction of correctly predicted positive instances among all predicted positive instances.

Recall ®

R = (True Positives) / (True Positives + False Negatives)

It quantifies the algorithm’s ability to find all positive instances.

F1 Score (F1)

F1 = 2 × (Precision × Recall) / (Precision + Recall)

The F1 score provides a balanced measure of the algorithm’s performance, as it is the harmonic mean of precision and recall.

Average Precision (AP)

AP = ∑(P_i × ΔR_i)

• P_i is the precision value at the i-th recall point.
• ΔR_i is the change in recall from the i-th to the (i+1)-th recall point.

AP summarizes the performance of an algorithm across different confidence thresholds. It quantifies the precision-recall trade-off for a given class.

Mean Average Precision (mAP)

mAP = (AP₁ + AP₂ + … + AP_n) / n

• AP₁, AP₂, …, AP_n are the Average Precision values for each class.
• n is the total number of classes.

Intersection over Union (IoU)

IoU = (Area of Intersection) / (Area of Union)

It is used to determine the accuracy of localization, measuring the overlap between predicted bounding boxes and ground truth bounding boxes.

Inference Time

Time taken to make predictions on a single input image. It measures the time it takes for the algorithm to process the input and produce the output (bounding boxes, class predictions) without considering any external factors.

Processing Speed (FPS)

Time taken by the algorithm to process a given dataset or a single image.

Often represented as FPS (Frames Per Second), which indicates the number of frames (or images) that the algorithm can process per second.

It takes into account factors such as data loading, pre-processing, and post-processing steps in addition to the inference time.

Number of Parameters

The number of model parameters indicates the model’s complexity and memory requirements.

Memory Usage

It measures the amount of memory consumed by the algorithm during inference.
