Re: How PolynomialExpansion works

The result includes, essentially, all the terms in (x+y) and (x+y)^2, and so on up if you chose a higher power. It is not just the second-degree terms. On Fri, Sep 16, 2016 at 7:43 PM, Nirav Patel wrote: > Doc says: > > Take a 2-variable feature vector as an example: (x, y), if we want to expand

How PolynomialExpansion works

Doc says: Take a 2-variable feature vector as an example: (x, y), if we want to expand it with degree 2, then we get (x, x * x, y, x * y, y * y). I know polynomial expansion of (x+y)^2 = x^2 + 2xy + y^2 but can't relate it to above. Thanks -- [image: What's New with Xactly]
