    Study Notes

    Differentiation between Neural Networks

    • Recurrent Neural Networks (RNN) are differentiated from other neural networks by their ability to maintain a hidden state that captures information from previous inputs.

    Deep Neural Networks (DNN)

    • The defining feature of a Deep Neural Network (DNN) is its ability to learn complex patterns and representations in data by using multiple layers of neural networks.

    Deep Belief Networks (DBN)

    • In a Deep Belief Network (DBN), the algorithm used to learn a layer of features from visible units is the Contrastive Divergence algorithm.
    • The primary purpose of treating activations of previously trained features as visible units in DBN is to learn a new representation of the data that can be used to initialize the weights of a supervised neural network.

    Deep Learning vs Machine Learning

    • The primary distinction between Deep Learning and Machine Learning is that Deep Learning uses neural networks with multiple layers to learn complex patterns and representations in data, whereas Machine Learning uses a variety of algorithms to learn from data.

    Applications of Deep Learning
