We can use scipy.optimize.minimize() function to minimize the function.. The minimize() function takes the following arguments:. fun - a function representing an equation.. x0 - an initial guess for the root.. method - name of the method to use. Legal values: 'CG' 'BFGS' 'Newton-CG' 'L-BFGS-B' 'TNC' 'COBYLA' 'SLSQP' callback - function called after each iteration of optimization.

In scipy, you can use the Newton method by setting method to Newton-CG in scipy.optimize.minimize(). Here, CG refers to the fact that an internal inversion of the Hessian is performed by conjugate gradient >>>

def minimize(self, x0, **kwargs): ''' pf.minimize(x0) minimizes the given potential function starting at the given point x0; any additional options are passed along to scipy.optimize.minimize. The minimize() function provides a common interface to unconstrained and constrained minimization algorithms for multivariate scalar functions in scipy.optimize. To demonstrate the minimization function, consider the problem of minimizing the Rosenbrock function of the NN variables − $$f(x) = \sum_{i = 1}^{N-1} \:100(x_i - x_{i-1}^{2})$$ scipy / scipy / optimize / _minimize.py / Jump to Code definitions minimize Function minimize_scalar Function standardize_bounds Function standardize_constraints Function How to use scipy.optimize.minimize scipy.optimize.minimize(fun,x0,args=(),method=None, jac=None,hess=None,hessp=None,bounds=None, constraints=(),tol=None,callback=None,options=None) fun (callable)objectivefunctiontobeminimized x0 (ndarray)initialguess args (tuple,optional)extraargumentsoftheobjective functionanditsderivatives(jac,hes) Minimize a scalar function of one or more variables using Sequential Least Squares Programming (SLSQP).

I have a computer vision algorithm I want to tune up using scipy.optimize.minimize. Right now I only want to tune-up two parameters but the number of parameters might eventually grow so I would like to use a technique that can do high-dimensional gradient searches. scipy를 이용한 optimization. just do it.

As all optimization-algorithms within scipy.minimize are quite general, there will always be faster methods, gaining performance from special characteristics of your problem. It will be a trade-off, how much analysis and work is done to gain performance.
