Project overview

In this project, you’ll assume the role of a machine learning engineer tasked with building an image classifier to recognize handwritten digits. You’ll explore the challenges of image classification and compare different models, including neural networks, to improve handwriting recognition accuracy.

Throughout the project, you’ll gain hands-on experience with essential deep learning concepts and techniques. You’ll preprocess image data, train and evaluate various classification models, and iterate to enhance performance. By applying your skills in Python and machine learning libraries, you’ll develop a practical understanding of building effective image classifiers.

Objective: Use Python and deep learning to build an image classifier that accurately recognizes handwritten digits, gaining valuable experience in applying neural networks to real-world problems.

“Dataquest starts at the most basic level, so a beginner can understand the concepts. I tried learning to code before, using Codecademy and Coursera. I struggled because I had no background in coding, and I was spending a lot of time Googling. Dataquest helped me actually learn.”
