The capability to recognize patterns and predict outcomes based on past data through artificial intelligence (AI) — including deep learning (DL) within machine learning (ML) — has taken computing to the next level.
Machine learning (ML) is why an e-commerce company can highlight the products you are most likely to need based on your buying behavior or how a streaming provider comes up with the most compelling content suggestions based on your watch history.
Although systems supporting AI applications are considered smart, most don’t learn independently and often rely on human programming. For example, data scientists have to prepare inputs and select variables used in predictive analytics.
Deep learning can automatically do this without human intervention, as it is meant to learn and improve by itself through analyzing algorithms. Deep learning, with the help of artificial neural networks, tries to imitate how humans think and learn.
Deep learning has emerged as an influential piece of digital technology that enterprises leverage to optimize their business models and predict the best possible outcomes.

Deep learning features
Supervised, semi-supervised, and unsupervised learning
Supervised learning is the simplest learning method, as it assumes the labels of each given image and makes the learning process for the network easier. Semi-supervised learning is used to train an initial model by employing a few labels and then repeatedly applying them to a greater number of unlabeled data. Unsupervised learning uses algorithms to identify patterns in a dataset, including data points that are not classified or labeled.
Deep learning acts as a comprehensive neural network. Hence, it possesses a large number of interconnected neurons organized in layers. The input layer receives information. Several hidden layers process the information, and the output layer provides valuable results.
Deep learning algorithms depend more on high-end machines as compared to ML applications. They require advanced GPUs to process heavy workloads. A huge amount of data, structured or unstructured, can be processed with deep learning, and the performance also improves as more data is fed.
Hyperparameters, like batch size, learning rate, momentum, and several epochs or layers, need to be tuned well for better model accuracy, since they connect layer prediction and final predicted output. Over-fitting and under-fitting can be well adjusted in deep learning using hyperparameters.
