    Study Notes

    Artificial Neural Networks

    • A simple neural network can be represented by the equation: 𝒇𝟏 : 𝒚 = 𝑨 ∗ 𝒙𝟏 + 𝑩 ∗ 𝒙𝟐 + 𝑪
    • The task of the network is to find A, B, and C.

    Neural Network Architecture

    • A neural network can have multiple layers: input layer, hidden layer, and output layer.
    • The number of layers and neurons in each layer can vary depending on the problem.

    Neural Network Classification

    • Neural networks can be classified into:
      • Shallow Neural Networks (1 or 2 hidden layers)
      • Deep Neural Networks (more than 2 hidden layers)

    Shallow Neural Networks

    • Use a maximum of two hidden layers to find mathematical relations between training data sets.
    • Data sizes are typically limited to 1,000 examples.

    Deep Neural Networks

    • Have more than two hidden layers, which can be over 100 layers.
    • Applications include:
      • Fault detection and classification in power systems
      • Load estimation for electric devices and power systems
      • Optimization of solar and wind power generation
      • Self-driving/autonomous cars

    Fully-Connected Neural Networks (FCN)

    • Also known as dense neural networks or multi-layer perceptron (MLP).
    • Every neuron in one layer is connected to every neuron in the subsequent layer.
    • Information flows from the input layer through one or more hidden layers to the output layer.

    Convolutional Neural Networks (CNN)

    • Building blocks of these networks are filters that extract relevant features using the convolution operation.
    • Generally deal with “Matrices” data inputs.

    Recurrent Neural Networks (RNN)

    • Building blocks of these networks are neurons with recurrent loops in the hidden layer.
    • Inputs are processed in both forward and backward directions.
    • Generally deal with “Sequence” data inputs.

    Neural Network Applications in Electrical Engineering

    • Neural networks have been used in electrical engineering applications, such as:
      • Fault detection and classification in electric devices
      • Load estimation for electric devices and power systems
      • Optimization of solar and wind power generation
