Typo on Page 38? #64

Closed claudio525 closed 2 years ago

I think there is a typo in the last line of the screenshot (bottom of page 38); shouldn't the summation on the right be over the weights/inputs, i.e. $j$ instead of $i$ (training samples)?

You are absolutely right, it should be

$$\sum_j wj x^{(i)}{j} + b$$

Will add it to the errata. Thanks for posting!
