第四步:使用threshold_max = np.argmax(accur) # 获得准确率最大的索引值,即为thresholds最好的索引值 defcalculate_roc(thresh, dist, actual_issame): pre_issame=np.less(dist, thresh) tp= np.sum(np.logical_and(pre_issame, actual_issame))#正样本被预测为正样本fp = np.sum(np.logical_and(...
np.set_printoptions(threshold=6) a = np.arange(15) a # > array([ 0, 1, 2, ..., 12, 13, 14]) 1. 2. 3. 4.24. 如何打印完整的numpy数组而不截断 难度等级:L1 问题:打印完整的numpy数组a而不截断。 给定: np.set_printoptions(threshold=6) a = np.arange(15) a # > array([ 0,...
我希望能有一些优雅的方式在所有元素上进行映射(thresholdfunc())。请注意,虽然它的类型为csr_matrix,但它实际上并不稀疏,因为它只是涉及稀疏矩阵的另一个函数的返回。 浏览3提问于2017-07-03得票数 1 回答已采纳 3回答 使用np.where创建具有三个条件的新列 、、、 如何在np.where()中获得三个条件。通常它...
this placed an upper limit on the size of the IR to be less than 2 kb. Three of 18 novel inversions passed these criteria predicted from npInv. We checked inversion 4q35.2 (NHEJ), 3
We simulated a diploid human chromosome 21 with three types of inversions: non-allelic homologous recombination (NAHR), non-homologous end joining (NHEJ) with size less than 4 kb and NHEJ with the size between 4 kb to 1 Mb (n = 61, 100 and 100, respectively). Software Lumpy [16], ...
To calculate the appropriate sample size, power analyses were carried out to determine the number of rats needed (Sigmaplot, Systat, Germany) using a power 40.8 and a type I error threshold α = 0.05. Two-sided parametric statistical tests were used in case data met normality and ...
Within this scheme, the sub- threshold dynamics of a wide class of integrate-and-fire type neuron models can be integrated exactly from one grid point to the next. However, the loss in accuracy caused by restrict- ing spike times to the grid can have undesirable consequences, which has led...
