Understanding What Units
Compute
•
Suppose you have a 2-input unit with a step
function and a fixed threshold t.
•
Let x, y be inputs.
•
What set of points on the x-y plane are at
the unit's threshold? (Simplify equations.)
•
Answer: The line W
x,i
´
x + W
y,i
´
y = t
–
rewritten: y = (-W
x,i
/W
y,i
)x + (t/W
y,i
)
