What is Deep Learning?
Deep learning is a branch of machine learning that uses artificial neural networks to perform tasks like classification and regression. These networks consist of multiple layers of neurons, which process data in stages.
The term “deep” comes from having three or more layers, enabling the network to learn complex patterns. Unlike traditional machine learning, deep learning can automatically extract features from raw data, making it powerful for tasks such as image recognition and natural language processing.
Inspired by the human brain, deep learning models use artificial neurons to mimic how we think and learn. Although early neural networks were based on brain structures, they do not exactly replicate brain functions.
Deep learning supports various learning methods, including supervised, semi-supervised, and unsupervised learning. The concept of deep learning was first introduced by Rina Dechter in 1986 and later by Igor Aizenberg in 2000, focusing on Boolean threshold neurons.
Today, deep neural networks are essential in advancing artificial intelligence and are used in applications like speech recognition and computer vision.
Key Components of Deep Learning
Deep learning uses neural networks with hidden layers to find patterns in data. Tools like TensorFlow and GPUs help these networks learn efficiently from large datasets.
Neural Networks
Neural networks are artificial neural networks (ANNs) inspired by the human brain. They consist of layers of connected neurons that process data. An input layer receives information, hidden layers analyze it, and an output layer delivers the result.
Learning algorithms adjust the connections based on training data. Early neural nets were simple and did not fully mimic brain functions.
There are different types of neural networks. Fully connected networks link every neuron to the next layer. Deep belief networks have multiple hidden layers to learn complex patterns.
Recurrent neural networks (RNNs) use feedback loops to handle tasks like language processing. These structures enable neural nets to perform tasks such as image classification and natural language processing.
Deep Neural Networks
Many layers make up deep neural networks, ranging from three to thousands. Each layer transforms data, forming a credit assignment path (CAP) from input to output. In feedforward networks, depth equals hidden layers plus one.
A CAP depth over two defines deep learning. These networks support tasks like image recognition and natural language processing (NLP). Researchers such as Geoffrey Hinton and Yoshua Bengio developed advanced deep neural networks.
