Brief info on Feature Engineering

Let's start with a good definition of Feature engineering "Feature engineering is the process of transforming raw data into features that better represent the underlying problem to the predictive models, resulting in improved model accuracy on unseen data." 👉 Why is Feature Engineering Crucial? Short Answer: Imagine constructing a magnificent building on a weak foundation - the result would be instability and fragility. Similarly, without thoughtful feature engineering, even the most advanced machine learning algorithms can stumble. 👉 The Art and Science of Feature Engineering. Feature engineering is both an art and a science. It is a highly iterative process that requires constant evaluation and refinement. It involves a feedback loop, where insights gained from model performance guide the creation of new features or adjustments to existing ones. Some of more well known techniques are listed below 1.

Quick Guide on Quantum Computing

 INTRODUCTION: Welcome to this beginner’s guide to quantum computing! In this blog, we will explore the basics of quantum computing, how it works, and what it can do. By the end of this video, you will have a solid understanding of quantum computing and its potential to revolutionize the world of computing and technology. PART 1: BASICS OF QUANTUM COMPUTING Let’s start with the basics. In classical computing, bits represent either a 0 or a 1. In contrast, in quantum computing, qubits represent a superposition of 0 and 1, which allows for faster and more complex computing. One important concept to understand in quantum computing is entanglement. This refers to the way in which qubits can become connected or entangled with one another. This allows for information to be transmitted between qubits, making quantum computing a powerful tool for communication and encryption.
