Content created by webstudio Richter alias Mavicc on March 30. 2017.. In the last tutorial we coded a perceptron using Stochastic Gradient Descent. This is very similar to the earlier exercise where you implemented linear regression "from scratch" using scipy.optimize.minimize.However, this time we'll minimize the logistic loss and compare with scikit-learn's LogisticRegression (we've set C to a large value to disable regularization; more on this in Chapter 3!).. The log_loss() function from the previous exercise is already defined in 2018-08-18 Description.

For multivariate functions, ``scipy.optimize.minimize`` provides an interface to methods for unconstrained optimization (`fmin`, `fmin_powell`, `fmin_cg`, `fmin_ncg`, `fmin_bfgs` and `anneal`) or constrained optimization (`fmin_l_bfgs_b`, `fmin_tnc`, `fmin_cobyla` and `fmin_slsqp`).
