What is Deep Learning?

Deep Learning is a subset of Machine Learning that uses artificial neural networks to process data and solve complex problems. These neural networks are inspired by the human brain and consist of multiple layers that help computers learn patterns from large amounts of data.

Deep learning algorithms can automatically learn features from data such as images, text, audio, and videos without manual programming.

Deep Learning Definition

Deep Learning is a branch of Artificial Intelligence that trains computers to learn from large datasets using multi-layer neural networks.

How Does Deep Learning Work?

Deep learning works through layers of artificial neurons called neural networks.

Main Components of Deep Learning

1. Input Layer

The input layer receives raw data such as images, text, or audio.

2. Hidden Layers

Hidden layers process information and identify patterns. Deep learning models can contain dozens or even hundreds of hidden layers.

3. Output Layer

The output layer provides the final prediction or result.

Neural Networks in Deep Learning

Artificial Neural Networks (ANNs) are the foundation of deep learning. These networks simulate the way the human brain processes information.

Types of Neural Networks

Convolutional Neural Networks (CNN)

CNNs are mainly used for image recognition and computer vision tasks.

Recurrent Neural Networks (RNN)

RNNs are used for sequential data such as text processing and speech recognition.

Transformer Networks

Transformers power advanced AI models like chatbots and language models.
