Description

Issue Description

  • As I know, before training yolo2, we need provide priorBoxes for our model, but the HouseNumberDetection example did not explain how to compute it. I hope dl4j can provide some method that can compute priorBoxes by k-means algorithm base training data.

Version Information

  • 1.0.0-beta2

Contributor guide

Research direction
Research existing implementations of k means clustering for YOLO anchor boxes, then implement a utility method in the HouseNumberDetection example to compute prior boxes from training data.
