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
