WebJun 14, 2024 · The derivative of z1 with respect to the rest of the weights is 0. This makes the whole matrix rather simple to derive, since it is mostly zeros. Where the elements are not zero (i.e. where i = k), then the value is xj. Here is the corresponding Python code to calculate that matrix. 1 2 3 4 5 6 7 8 9 10 11 12 def z_dir (Z, W, x): WebDictionary. Dictionaries are used to store data values in key:value pairs. A dictionary is a collection which is ordered*, changeable and do not allow duplicates. As of Python version 3.7, dictionaries are ordered. In Python 3.6 and earlier, dictionaries are unordered. Dictionaries are written with curly brackets, and have keys and values:
