introduction

%%visits: 2 ## intuition Think back to the idea of forming a line from a set of points. Now the word “linear” does not mean straight line, but rather, linearity in terms of vectors.

So how does the graph come from the equation, Y_i = β₀ + β₁X_i (I have set the ϕ function to be the trivial map in this case) Now the parameters, β₀, β₁ are the y-intercept and slope respectively

Now any “x” on the graph are mere data points

%% ==rigour ## exam clinic {{file:../figures/screenshot_20220118_122016.png}} This was a mistake in my intuition, I thought that the three types of cars would become the basis functions,ϕ, which can encode in them the required things. %% ==examples and non-examples %% ==resources tags :math:
