Neural Networks and Deep Learning Algorithms

Algorithm	Description, Time Complexity & Use Case
Artificial Neural Networks (ANN)	Artificial Neural Networks (ANN) are computational models inspired by the human brain’s neural networks, consisting of interconnected nodes (neurons) organized in layers. They are designed to recognize patterns and classify data. Time complexity: O(n * m * k) per epoch, where n is the number of samples, m is the number of layers, and k is the number of neurons in each layer. Use case: Widely used in classification tasks, such as image and speech recognition.
Convolutional Neural Networks (CNN)	Convolutional Neural Networks (CNN) are specialized neural networks primarily used for processing grid-like data, such as images. They employ convolutional layers to automatically extract features from the input data, allowing for spatial hierarchy in data representation. Time complexity: O(n * k * p * q), where n is the number of images, k is the number of filters, and p, q are the dimensions of the input image. Use case: Commonly applied in image and video recognition, as well as in medical image analysis.
Recurrent Neural Networks (RNN)	Recurrent Neural Networks (RNN) are designed to handle sequential data by using loops to allow information to persist. They are effective in tasks where context and order matter, such as time-series analysis and natural language processing. Time complexity: O(n * t), where n is the number of time steps and t is the number of features. Use case: Used in language modeling and text generation, as well as speech recognition.
Long Short-Term Memory (LSTM)	Long Short-Term Memory (LSTM) networks are a type of RNN that addresses the vanishing gradient problem by incorporating memory cells that can store information over long periods. This architecture is particularly useful for learning from long sequences. Time complexity: O(n * m * k), where n is the number of samples, m is the number of layers, and k is the number of time steps. Use case: Commonly used in applications like machine translation and speech synthesis.
Generative Adversarial Networks (GANs)	Generative Adversarial Networks (GANs) consist of two neural networks, a generator and a discriminator, that compete against each other. The generator creates fake data while the discriminator attempts to distinguish between real and fake data, resulting in highly realistic generated data. Time complexity: O(n * m), where n is the number of training samples and m is the number of epochs. Use case: Frequently used in image generation, video synthesis, and generating realistic data for training models.
Transformer Models	Transformer Models utilize self-attention mechanisms to weigh the significance of different words in a sequence, allowing for parallelization and improved performance in processing sequential data. They are highly effective for natural language processing tasks. Time complexity: O(n^2), where n is the sequence length. Use case: Commonly employed in language translation, text summarization, and question-answering systems.
