The performance of a machine learning model can be characterized in terms of the bias and the variance of the model. A model with high bias makes strong assumptions about the form of the unknown underlying function that maps inputs to outputs in the dataset, such as linear regression. A mod...

In order to answer this question I needed to check the implementation. Because indeed the variance of the last 100 samples of b is zero, and the rolling correlation is computed as a.cov(b) / (a.var() * b.var())**0.5. After some search I found the rolling variance implemen...
Python Profilers, like cProfile helps to find which part of the program or code takes more time to run. This article will walk you through the process of using cProfile module for extracting profiling data, using the pstats module to report it and snakev
How to Compress Images in PythonThis tutorial will teach us how to compress the given image using the Python script. Image compression is a process of reducing an image's size without degrading the image quality. There are many tools available on the internet where we need to upload and ...
observation. Independence can be achieved by using random sampling or experimental designs that account for potential confounding factors. In cases where independence can’t be assumed, alternative tests such as mixed-effects models or repeated measures analysis of variance (ANOVA) may be more ...
In Python, the default limit is a few thousand levels of such calls: Python >>> import sys >>> sys.getrecursionlimit() 1000 This won’t be enough for a lot of recursive functions. However, it’s very unlikely that a binary search in Python would ever need more due to its ...
