- How to draw a hyperplane in Support Vector Machine | Linear SVM - Solved Example by Mahesh Huddar
Points (4, 1), (4, -1), and (6, 0) belong to class positive, and
points (1, 0), (0, 1) and (0, -1) belong to the negative class.
Draw an optimal hyperplane to classify the points.
The following concepts are discussed:

I am getting alpha2=alpha3 , 7/18 , my friend also verified it ! Kindly confirm & reply back sir
yes and alpha1=-2.4
same
same
yeah same here
Was literally looking for a video like this more than a month ago! Thanks for uploading ❤❤❤

How you find alpha 1,2,3 IN TIME 5:10
Very nice explanation thank u

This might be a dumb question but if the bias is -2 why is it plotted on +2, maybe i'm not understanding something but if you could clear that up that would be great
It’s actually b-2 =0 so b = 2
When we equate -2 with 0 the value of b becomes +2.
But gradient is (1,1) but he drawn for (-1,1)
Is this alphas are correct
just put y = 0 , and plot the line , since y is the label which is 0 for the hyperplane / decision boundary
I am searching from long how to determine if the given point is positive or negetive example
did you find it?
@@tamannakhan2579 no; but when i had started reading more then it was more clear that +ive and -ive is just a classification but i was confused earlier by relating it with co-ordinate.
So, try to relate it with classification as the background mathematics is complex for me to understand in deep level.
ML algorithms are already taken care all the background mathematics hence at high level i tried to understand the mathematics behind it and rest of the things i left it to ML algorithms.
@@tamannakhan2579 since this is binary classification, we have two classes present in the dataset. One of them is represented by +1 while the other is -1
Superb
Thank You

How can find the alpha values....?
Use Elimination Method
can you help me? i have a task to draw hyperplane (no coding). my data has multiclass (4 classes) and i only found 2 classes examples. it's too confusing for me
Did you find any solution?
Can you please share some link to help me?
@@laibarukhsar7359 there is no link for it. i just asked to every yt channels i watched. heres my conclusion:
1) use 1 vs All approach. so if you have 4 classes, there will be 4 methods: A vs All (B,C,D), B vs All (A,C,D), C vs All (A,B,D), D vs All (A,B,C). you need to calculate all methods
@@laibarukhsar7359 2) use the formula norm euclidean. ||w||=√w1^2 + w2^2
b has default value = 1. so calculate each data with the form. and if there are 2 or more results with value near 1. then choose 2 datas as vectors
How to identify positive and negative points
There are given in question 😅
