Here m denotes the number of examples in your training set, not the number of features.

http://www.johnny-lin.com/py_pkgs/atmqty/doc/theta.html If you don't escape the '\' python interprets your string as it should include a tab (to which the sign is \t). That is exactly why get 'heta' and a tab in front of it. The solution suggest by joris is also possible, since it tells python to pass a raw string to latex and not interpret it.

WebBig-Theta tells you which functions grow at the same rate as f (N), for large N Big-Omega tells you which functions grow at a rate <= than f (N), for large N (Note: >= , "the same", and <= are not really accurate here, but the concepts we use in asymptotic notation are similar):
WebGradient descent is an optimization algorithm that works by efficiently searching the parameter space, intercept ( θ 0) and slope ( θ 1) for linear regression, according to the following rule: θ := θ − α δ δ θ J ( θ).
