Instead of relying on predefined rules, ML models identify patterns, make predictions, and improve their performance over time by analyzing vast datasets. Google utilizes various ML techniques, including supervised learning (where the algorithm learns from labeled data), unsupervised learning (where the algorithm finds patterns in unlabeled data), and reinforcement learning (where the algorithm learns through rial and error).
Deep Learning (DL): A subfield of ML, deep learning employs artificial neural networks with multiple layers (hence “deep”) to analyze complex data in a hierarchical manner. Inspired by the structure of the human brain, these neural networks can learn intricate features and representations from raw data, enabling them to tackle highly complex tasks such as image recognition, natural language processing, and speech recognition with remarkable accuracy.
Neural Networks: The fundamental building blocks of deep learning are artificial neural networks. These networks consist of interconnected nodes (neurons) organized in layers. Each connection has a weight associated with it, and the network learns by adjusting these weights based on the training data. The ability of deep neural networks to learn intricate patterns and relationships in massive datasets is the key to many of Google’s AI breakthroughs.
