Webb我遵循他们的建议，并设法在这个数据集上训练模型。由于处理能力的限制，我只使用了数据集的三分之一，并对培训和测试数据进行了70:30的分割。我使用了更快的\u rcnn\u resnet101模型。我的配置文件中的所有参数都与TF提供的默认参数相同 http://scikit-learn.org.cn/view/112.html Webb7 jan. 2016 · 3. in creating cov matrix using matrix M (X x Y), you need to transpose your matrix M. mahalanobis formula is (x-x1)^t * inverse covmatrix * (x-x1). and as you see first argument is transposed, which means matrix XY changed to YX. in order to product first argument and cov matrix, cov matrix should be in form of YY. chuul dnd stats
