A binary tree is one where each of its nodes has maximum two children nodes. These children are mostly known as Left and Right child. 1. In-order Traversal It goes from left child then current node then right childSo for the given tree above it will be: [2,17,7,19,3,100,25,36,1] 2. Pre-order Traversal It first deals with […]

First check out the problem description here on LeetCode. The Solution This is marked as a medium difficult problem. However if you know what in-order traversal does, it is a very simple problem. Here I just added a helper traverse() method. All the trick is done in the few lines inside the function. It checks […]

## Queue Data Structure

Discussion on the implementation of queue data structure

This is the recommended template for a Project Proposal for a freelance Machine Learning project. This is my personal choice, and definitely depending on project requirements, you might need to explicitly modify change/modify/add to this list.

Random Projection is an interesting Dimensionality Reduction technique. You may choose to create a random projection for 1,2,3,..,n dimensional projections. Now how to tell which one is best? So you would need to calculate loss of data due to this reduction in data size. # data has this shape: row, col = 4898, 11 random_projection […]
