What is a decision tree in machine learning? Decision trees, one of the simplest and yet most useful Machine Learning structures. Decision trees, as the name implies, are trees of decisions. Taken from here You have a question, usually a yes or no (binary; 2 options) question with two branches (yes and no) leading out of the tree.
Humanity is dying, we need to save the bees “The bee is more honored than other animals, not because she labors, but because she labors for others.” — St. John Chrysostom.

Big Omega Big Omega Whereas Big O measures the upper bound (the maximum amount of time something can take) Big Omega (using the symbol Ω) measures the best running time. We say that $f(n)$ is $Ω(g(n))$ if there are real constants c and $n_0$ such that: $$f(n)
A Primer on Search Algorithms “It’s written, ‘seek and ye shall find’. But first, ‘imagine what you seek’. Otherwise, you will end up searching everything everywhere forever.” Toba Beta, My Ancestor Was an Ancient Astronaut This article will be a primer on search algorithms used in Artificial Intelligence.

Weekly Thoughts Hey! This is a new newsletter I am trialing. Basically, with previous newsletters I had to stick to a certain topic. Which sucks. I obsess over new things all the time. Soooo…. This newsletter is just a mish-mash of things I think about, and things I learn. Enjoy! :) An Algorithm
Algorithmic Design Paradigms Greedy Algorithms Greedy algorithms aim to make the optimal choice at that given moment. Each step it chooses the optimal choice, without knowing the future. It attempts to find the globally optimal way to solve the entire problem using this method. Why Are Greedy Algorithms Called Greedy? Algorithms are called

Algorithms Featured What Is Dynamic Programming With Python Examples Dynamic programming is breaking down a problem into smaller sub-problems, solving each sub-problem and storing the solutions to each of these sub-problems in an array (or similar data structure) so each sub-problem is only calculated once. It is both a mathematical optimisation method and a computer programming method. Optimisation problems
Algorithms How to Share a Secret (Diffie-Hellman-Merkle) Diffie-Hellman-Merkle is a way to share a secret key with someone (or something) without actually sending them the key. Before we look into how we share keys let’s first look into what keys are and why we would want to invent a method to share keys without giving the
