Q1. What is the difference between list and tuples in Python? LIST vs TUPLES LIST TUPLES Lists are mutable i.e they can be edited. Tuples are immutable (tuples are lists which can’t be edited). Lists are slower than tuples. Tuples are faster than list. Syntax:… Read More »Python Interview Question Section 1
Image Processing with SciPy – scipy.ndimage scipy.ndimage is a submodule of SciPy which is mostly used for performing an image related operation ndimage means the “n” dimensional image. SciPy Image Processing provides Geometrics transformation (rotate, crop, flip), image filtering (sharp and de nosing), display image,… Read More »Image Processing with SciPy – scipy.ndimage
Nelder –Mead Algorithm: Nelder-Mead algorithm selects through method parameter. It provides the most straightforward way of minimization for fair behaved function. Nelder – Mead algorithm is not used for gradient evaluations because it may take a longer time to find the solution. import numpy as… Read More »Nelder –Mead Algorithm
Optimization and Fit in SciPy – scipy.optimize Optimization provides a useful algorithm for minimization of curve fitting, multidimensional or scalar and root fitting. Let’s take an example of a Scalar Function, to find minimum scalar function %matplotlib inline import matplotlib.pyplot as plt from scipy import optimize import… Read More »Optimization and Fit in SciPy – scipy.optimize
Discrete Fourier Transform – scipy.fftpack DFT is a mathematical technique which is used in converting spatial data into frequency data. FFT (Fast Fourier Transformation) is an algorithm for computing DFT FFT is applied to a multidimensional array. Frequency defines the number of signal or wavelength… Read More »Discrete Fourier Transform – scipy.fftpack
Linear Algebra with SciPy Linear Algebra of SciPy is an implementation of BLAS and ATLAS LAPACK libraries. Performance of Linear Algebra is very fast compared to BLAS and LAPACK. Linear algebra routine accepts two-dimensional array object and output is also a two-dimensional array. Now let’s… Read More »Linear Algebra with SciPy
