Data Science and Machine Learning (Theory and Projects) A to Z - Data Preparation and Pre-processing: Handling Image Dat

The video tutorial discusses various data formats, focusing on image data and how it can be converted into numeric features for machine learning. It explains the concept of feature vectors, including basic pixel values and advanced features like HOG and LBP. The tutorial also highlights the role of convolutional neural networks (CNNs) in learning features from images, emphasizing their effectiveness over traditional methods when large datasets are available.
