I am confused here about the first regularization term in the ‘put them together’ part; Can someone help explain why the **‘w’ term** has a subscript **k** on it? I thought k just specifies between the different features (romance (1) or action (2))? Thank you!

Hello @Jan_Z,

Thank you for sharing the link and the screenshot!

You are right that a k means a feature, but for each feature, shouldn’t there be a w and a x at the same time, otherwise, what would x multiply to?

Cheers,

Raymond

Right, and this is highlighted here:

So when **k** goes from 1 to **n**, is n equal to 2 in this case. Would k=1 and 2 for each weight w just specify which weight is selected inside of the weight vector?

Thanks!
