NOTES ON STATISTICS, PROBABILITY and MATHEMATICS

Example of Non-Linear Classification:

From Andrew Ng ML course:


Simplifying the classification problem on the right as a binary \(0/1\) \(x_1\) and \(x_2\) prediction we have the equivalent of an XOR gate:


In fact, if the circles are zeros, the model is more of an XNOR function: \(y = x_1 \text{XNOR} x_2 = \text{NOT} (x_1 \text{XOR} x_2)\).
