What binary threshold neurons cannot do
										Data Space (not weight space)
	• A binary threshold output unit cannot even tell if two single bit numbers are the same! Same:     (1,1)  1;  (0,0)  1 Different: (1,0)  0;  (0,1)  0 • The four input-output pairs give four inequalities that are impossible to satisfy:
												1,1
												1,0
				0,0
			The positive and negative cases cannot be separated by a plane
