Making statements based on opinion back them up with references or personal experience. Optimize regarding to one variable in a contour plot involving a complex integral. Peano shows that it's not hard to produce a useful set of axioms that can prove 1+12 much more easily than Whitehead and Russell do. ![]() This might be a question more suited for chat, or a comment below a post where this abbreviation was used. The main reason that it takes so long to get to 1 + 1 2 is that Principia Mathematica starts from almost nothing, and works its way up in very tiny, incremental steps. If you type mma inside a text cell, it will automatically replace it with Mathematica. Provide details and share your research But avoid Asking for help, clarification, or responding to other answers. It probably comes from the fact that mma is an official shortname for Mathematica. Predict predictor, opts takes an existing predictor function and modifies it with the new options given. Predict ' name', input uses the built-in predictor function represented by ' name'. Xi = np.hstack((xi, np.ones((1,len(xi))).T )) Thanks for contributing an answer to Mathematics Stack Exchange Please be sure to answer the question. Predict training, input attempts to predict the output associated with input from the training examples given.
