Machine learning is an area of computer science that gives computers the ability to learn without being explicitly programmed. It focuses on the development of computer programs that can teach themselves to grow and change when exposed to new data.
Deep Learning is a subset of machine learning in artificial intelligence (AI) that has networks capable of learning unsupervised from data that is unstructured or unlabeled. Also known as deep structured learning or hierarchical learning, Deep Learning models are arranged in a layered, hierarchical manner.
These are not interchangeable terms; rather, they describe different branches of artificial intelligence. Machine learning is the umbrella term for AI, and includes both unsupervised and supervised forms. Deep Learning provides the ability to model complex relationships between input variables and labels/outputs by using non-linear processing units (such as artificial neurons) called “hidden layers”. This type of neural network is quite different from traditional ones because it’s more accurate and faster at processing data.
What is Deep Learning?
The term deep learning refers to a set of algorithms used to build artificial neural networks (ANNs). ANNs are computing systems that are inspired by the human brain. They are designed to learn, recognize patterns and make intelligent decisions based on what they have learned.
Deep learning is a subset of machine learning, which is an application of artificial intelligence (AI) that focuses on building systems and models that learn from experience. Machine learning uses statistical techniques to discover patterns in data and then learn from it.
The deep part of deep learning comes from the fact that these ANNs consist of multiple layers of interconnected nodes (the neurons) between the input and output layers. For example, a simple neural network has one input layer, one hidden layer, and one output layer.
Deep learning algorithms use multiple hidden layers, each containing a complex network of neurons. The deeper the network gets, the more complex the patterns it can learn. Moreover, it allows them to learn features directly from raw data without relying on feature engineering. Feature engineering is a process in which humans extract essential features from raw data using their domain knowledge.
How Does Deep Learning Work?
A machine learning algorithm is a recipe for generating a statistical model. The actual steps in the recipe might be complicated, but the underlying structure is simple:
1. Take in data.
2. Learn from data.
3. Use what you learned to make predictions about new data.
Deep learning algorithms go through this same procedure, but with more than one layer of learning (hence “deep”). They are called deep because they make a sequence of transformations on their inputs. Each program in the hierarchy performs a nonlinear mapping on its input and uses what it learns to generate a statistical model as output. These outputs can then be used as inputs to the next higher level of learning, which generates another statistical model and so on until we reach the final output layer that generates predictions.
The most important aspect of deep learning is that these models learn features or representations automatically from data that help them make better predictions, compared to other machine learning models that require human hand-coded features or representations. This ability to learn representations directly from raw data is critical because it allows us to build much more efficient and powerful models than humans could ever code by hand.
Significance of Deep Learning
Deep learning is a class of machine learning algorithms that employ hierarchical representations of data, such as neural networks, to extract useful information from large amounts of data. It is capable of learning complex functions from examples, unsupervised. The human brain uses deep learning to make sense of the world around us; similarly, deep-learning programs are being used to power self-driving cars, detect fraud in financial transactions, and make medical diagnoses.
Deep Learning is being aggressively invested in by major technology firms since it has become vital in every industry as a means of making machines smarter. It can be used to enhance the performance of computers in a number of ways such as image recognition and speech recognition. A few years ago, image recognition was one the most challenging applications for computers; however, with the advent of deep learning, it has become possible to construct systems that perform this task with high accuracy.
Deep learning has made it possible for computer vision models to learn from unlabelled data which is similar to how humans learn from their environments. This makes it possible for machines to adapt and get more accurate over time thanks to their unique capabilities for detecting patterns and carrying out predictive analytics.
