Wide and deep learning is an artificial intelligence (AI) approach combining the use of supervised and unsupervised machine learning. Wide and deep learning uses both shallow and deep neural network architectures to model large datasets with both low and high-level features. The result is a powerful learning system capable of both generalizing patterns from past data and quickly adapting to new information.
Wide learning is the use of shallow networks to recognize specific patterns in a dataset. This approach typically consists of a single layer of nodes, with one input layer and one output layer – making it computationally fast and inexpensive. Because of its simplicity, wide learning is better suited to datasets with plenty of signals that are easily identifiable.
Deep learning, on the other hand, is the use of multiple layers of deep neural networks to identify complex patterns in large datasets. Deep learning is significantly more computationally intensive than wide learning, but its ability to identify subtle relationships among large diverse data sets makes it well suited to recognizing patterns in datasets with fewer obvious signals.
Wide and deep learning combines the strengths of both models, using supervised learning to identify important signals from the input data, and then using deep neural networking to identify more complex patterns. By training multiple layers for deep learning, the model can find more nuanced patterns than either alone. This can lead to more accurate predictions and greater overall performance.
Wide and deep learning is highly effective for applications such as image recognition, natural language processing, and speech recognition. It is becoming more prevalent as computing power and storage capacity increase – making it possible to build larger and more sophisticated models. As the technology improves, it can be applied to a wider range of problem domains.
