Topic 1 Question 63
You have some data, which is shown in the graphic below. The two dimensions are X and Y, and the shade of each dot represents what class it is. You want to classify this data accurately using a linear algorithm. To do this you need to add a synthetic feature. What should the value of that feature be?
X2+Y2
X2
Y2
cos(X)

For fitting a linear classifier when the data is in a circle use A.

The 2 variables that make a circle in http://playground.tensorflow.org are x1^2 and x2^2. Sin(x) or cos(x) would just make horizontal stripes.
To do this you’d use those 2 variables, learning rate 0,3 for example, classification type, no regularization needed and any activation function will work fine.
