Developed by OpenAI, ChatGPT is a testament to the power of neural networks in generating coherent and contextually relevant human-like text.

What are the three types of neural network?

Neural networks come in various architectures, each suited for specific tasks. The three primary types are:

  1. Feedforward Neural Networks (FNN): Information flows in one direction, from input to output layer, without cycles.
  2. Recurrent Neural Networks (RNN): Connections form a directed cycle, allowing for the processing of sequential data.
  3. Convolutional Neural Networks (CNN): Primarily used for image processing, they excel in extracting hierarchical features.

What are neural networks used for?

Neural networks find applications across diverse domains, including:

  1. Healthcare: Diagnosing diseases from medical images using CNNs.
  2. Finance: Predicting market trends and optimizing trading strategies with recurrent neural networks.
  3. Natural Language Processing: Enhancing language translation, sentiment analysis, and chatbot interactions using various neural network architectures.

Why is CNN called a neural network?

CNNs derive their name from the broader family of neural networks due to their fundamental similarity in structure. The term "neural network" reflects their inspiration from the human brain, and the "convolutional" aspect denotes the specific mathematical operation employed in processing visual data.

Who invented neural networks?

The concept of artificial neural networks dates back to the 1940s, with Warren McCulloch and Walter Pitts pioneering the foundational model. However, significant advancements occurred in the 1980s when researchers like Geoffrey Hinton, Yann LeCun, and Yoshua Bengio made crucial contributions to the development of neural network architectures.

What are features in a neural network?

In a neural network, features are the distinctive attributes or patterns extracted from input data. For example, in image recognition, features could include edges, textures, and shapes. The network learns to recognize these features and combines them to make complex decisions.

What is the full form of RNN?

RNN stands for Recurrent Neural Network. Unlike traditional feedforward neural networks, RNNs possess connections that create loops, allowing them to exhibit dynamic temporal behavior. This makes them well-suited for tasks involving sequential or time-dependent data.

What are CNN layers?

CNNs consist of multiple layers, each serving a specific purpose:

  1. Convolutional Layers: Detect patterns like edges and textures in the input data.
  2. Pooling Layers: Reduce spatial dimensions, retaining essential information.
  3. Fully Connected Layers: Process features extracted by previous layers, making final predictions.
