Deep Learning

Input

Deep Learning

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. It is also known as deep neural learning or deep neural network.

What is Deep Learning?

Deep learning is a class of machine learning algorithms that:

1. Use a cascade of multiple layers of nonlinear processing units for feature extraction and transformation.
2. Each successive layer uses the output from the previous layer as input.
3. Learn in supervised (e.g., classification) and unsupervised (e.g., pattern analysis) manners.

How Does Deep Learning Work?

Deep learning architectures such as deep neural networks, deep belief networks, recurrent neural networks, and convolutional neural networks have been applied to fields including computer vision, speech recognition, natural language processing, audio recognition, social network filtering, machine translation, bioinformatics, drug design, medical image analysis, material inspection, and board game programs where they have produced results comparable to and in some cases superior to human experts.

Key Concepts in Deep Learning

Neural Networks

Neural networks are a series of algorithms that mimic the operations of a human brain to recognize relationships between vast amounts of data. They are a foundational element of deep learning.

Convolutional Neural Networks (CNNs)

CNNs are deep artificial neural networks that are used primarily to classify images, cluster them by similarity (photo search), and perform object recognition within scenes.

Recurrent Neural Networks (RNNs)

RNNs are a type of artificial neural network where connections between nodes form a directed graph along a temporal sequence. This allows it to exhibit temporal dynamic behavior. Used in areas such as speech recognition.

Training Deep Learning Models

Deep learning models are trained by using large sets of labeled data and neural network architectures that learn features directly from the data without the need for manual feature extraction.

Applications of Deep Learning

Deep learning is used in various sectors including but not limited to:

1. Autonomous Vehicles: For driving cars.
2. Healthcare: For disease detection and diagnosis.
3. Finance: For fraud detection.
4. Entertainment: For recommendation systems.
