Hello all, In my work I am using SVM for classification. I had trained the SVM classifier and also obtained the Lagrangian multiplier (α) which is a

column vector .

My query is how we can use this Lagrangian multiplier (α) to predict the labels of the data points.

Any help in this regard will be highly appreciated.

Thank you sir for your response....

I am using the paper " Supervised Learning-Based Semi-Blind Detection for Generalized Space Shift Keying MIMO Systems" for my work.

I am using SVM method for classification. The SVM classifier is trained using the training data in vector

having dimension

, the labels in vector

having dimension

So as per equation (5) of this paper, I had obtained 16 different α of dimension

My query in mathematical form is as follows:

How can I predict the labels of the test data say in vector

having dimension 404 x 4 ?
