Neural network AIs come in several types.
Depending on the problem that needs to be solved and the data that needs to be analyzed, different types of neural networks are utilized.
The most common type of neural network is the feedforward neural network. This neural network architecture is the simplest and it is mainly used for classification and regression problems. The data passes through the input nodes and then to the output nodes through hidden layers where the weighted sums and activation functions take place.
Another type is the convolutional neural network (CNN) which is popular in image recognition and computer vision applications. CNNs use convolution operations to recognize specific patterns on the input data, such as edges and shapes, in order to identify the object in the image.
Recurrent Neural Networks (RNNs) are commonly used in natural language processing and speech recognition. RNNs uses time-series data and takes into account the previous state of each input which makes it capable of recognizing patterns in sequential data.
Generative Adversarial Networks (GANs) are commonly used for unsupervised learning problems such as image generation, text generation or anomaly detection. GANs use a generator network and a discriminator network that work against each other to produce realistic data from scratch.
Overall, choosing the right type of neural network is crucial to the success of any AI project. When deciding the type of neural network architecture, it is important to understand the nature of the problem at hand and the type of data that needs to be analyzed.
