Merging Datasets in Python using Numpy, Pandas
Pandas provides powerful tools for complex data manipulations. For the large datasets, Pandas chunk processing is a better approach.
Generators in Python
This generator acts as a task manager, handling tasks sent to it one at a time and maintaining its state across calls.
Efficiently Merging Large Sorted Files
The solution involves using an external Merge sort algorithm for handling data that cannot fit into memory. We’ll use a two-pointer technique.
Understanding Linearity of Expectation
Linearity of expectation is a powerful concept in probability theory that simplifies the calculation of expected values in probabilistic experiments.
Normalization and Scaling in Python using ML Libraries
These plots visualize the distributions of the original data and the data after applying each normalization technique.
Gaussian Distribution in Normalization
Gaussian distribution or normal distribution, is significant in data science because of its frequent appearance across numerous datasets.
Normalization – Data Science
Normalization can improve the performance of machine learning algorithms, especially those that are sensitive to feature scales.
What is Data Science?
Data science encompasses a broader set of activities than machine learning, including data preprocessing, model selection and evaluation.
Sudoku Solver using Backtracking
Let’s implement a Sudoku solver using a backtracking & recursive algorithm for the grid of variable size (N x N).
