When I went on the O’Reilly platform, I was astonished to find all the books there, plus live events and sandboxes so you could play around with the technology.I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.I'm always learning.

Artificial Neural Networks ◾ 203
2. Design a perceptron for the following problem: the inputs to the net-
work are strings of six bits (i.e., there are six input neurons), and the
perceptron has six output neurons that count the number of bits,
which are 1 in the input strings as follows:
e output is 000000 if the input contains no 1’s.
e output is 100000 if the input contains a single 1 (its position is
unimportant).
e output is 110000 if the input contains two 1’s.
…
…
e output is 111111 if the input is all 1’s.
3. Can you design a perceptron for Exercise 2 if the output is represented
by the position of a single 1 in the output neurons? For instance:
100000 represents an input string containing a single 1.
