Hello.

2
00:00:00,690 --> 00:00:01,620
Welcome back.

3
00:00:01,640 --> 00:00:10,080
So when we create the matrices or Multidimensional arrays to hold our parameters we have to initialize

4
00:00:10,080 --> 00:00:10,750
them.

5
00:00:10,860 --> 00:00:17,970
We have to initialize the way to matrices with random values and dy bias matrices with zeros as we can

6
00:00:17,970 --> 00:00:20,160
see over here over here.

7
00:00:20,160 --> 00:00:27,960
Presumably this sort of function random into bracket row call would generate a matrix of row number

8
00:00:27,960 --> 00:00:33,690
of rows and call number of columns and fill the matrix with random numbers.

9
00:00:33,690 --> 00:00:36,390
We shall see how this is done in code right.

10
00:00:36,390 --> 00:00:38,600
So that's all the rest and I'll see you in the next lesson.
