TensorFlow
Deep learning-based image classification and detection.
Detailed Explanation
TensorFlow is a robust framework used primarily for deep learning applications, including image classification and detection. It allows developers to build complex models that can learn from large datasets of images, enabling systems to recognize patterns and make predictions about new images. For example, you can train a TensorFlow model to identify different types of fruits by showing it thousands of pictures of apples, oranges, and bananas.
Examples & Analogies
Think of TensorFlow as a classroom where a machine learns from examples. Just as a student learns to identify objects in pictures through practice and repetition, TensorFlow trains models by showing them many examples, until they can make accurate predictions on new, unseen images.
