What’s the question is asking?

#4

Hey @saksham_thukral

a) Surely it should be zero.
b) It lies on the margin, than also it will be zero. since no error is involved in classification, we can have multiple points lying on the margin
c) when it lies in the wrong side of the margin, than the error will be somewhere between 0 and 1
d) When it lies on the other side of decission boundary than it would be greater than 1.

you can visualize all these from graph of ei = max(0,1-ti).

So correct answer should be 0,0, between 0 and 1, >1. This option is not present currently, informed the backend team they will be resolving it very soon.

Hope this cleared your doubt. :blush:

Sorry for the trouble bhaiya ! but i got a little more confused now ,

  1. how this graph is made, is this the graph of hinge loss function and do i need to solve this question after studying that graph?
  2. if i am not wrong , ‘ei’ is the error or the extra cost that have to be added into the loss function and
  3. plz correct me if m wrong , the margin the basically the gap between the positive hyper plane and the negative hyper plane
    DO i need to consider these above three points to solve this question, Right?

Hey @saksham_thukral,

  1. yes this graph is of hinge loss, yes it would be easier if you draw graph first and than solve.
  2. yes on y axis its the same ei for the error term.
  3. Magin line here means positive and negative hyper plane.

Hope this cleared your doubt. :blush:

Got it , Thank u so much for the help :slight_smile:
