题目 Given two sorted integer arrays nums1 and nums2, merge nums2 into nums1 as one sorted array. Note: The number of elements initialized in nums1 and nums2 are m and n respectively. You may assume that nums1 has enough space (size that is equal to m + n) to hold additional elements from nums2. Example: [代码] Constraints: 10^9 <= nums1[i], nums2[i] <...
SPP (spatial pyramid pooling layer) SPP applies a slightly different strategy in detecting objects of different scales. It replaces the last pooling layer (after the last convolutional layer) with a spatial pyramid pooling layer. The feature maps are spatially divided into m×m bins with m, say, equals 1, 2, and 4 respectively. Then a maximum pool i...
1. explode hive wiki对于expolde的解释如下: explode() takes in an array (or a map) as an input and outputs the elements of the array (map) as separate rows. UDTFs can be used in the SELECT expression list and as a part of LATERAL VIEW. As an example of using explode() in the SELECT expression list, consider a table named myTable that has a single column (m...
