Multi-Layer Perceptron (MLP) for Mental Health Prediction

Multi-Layer Perceptron (MLP) is a class of feedforward artificial neural network. It consists of at least three layers: an input layer, hidden layers, and an output layer. Each neuron uses a nonlinear activation function.

MLP can model complex relationships in data to identify patterns associated with mental disorders. By learning from diagnostic data, MLP algorithms can potentially predict mental health issues with high accuracy.

Quality data is crucial. For mental health prediction, this includes symptoms, genetic information, and lifestyle factors. Data must be cleaned, normalized, and split into training and testing sets before use.

Identifying the most relevant features reduces complexity and improves MLP performance. Techniques like PCA are used to extract and select features that strongly correlate with mental health disorders.

In training, the MLP adjusts weights using algorithms like backpropagation. The goal is to minimize the difference between the predicted outcome and the actual diagnosis of mental health disorders.

Performance is assessed using metrics like accuracy, precision, recall, and F1-score. Cross-validation helps ensure that the MLP model generalizes well to unseen data.

Using MLP in healthcare requires careful consideration of ethics. Issues like data privacy, consent, and potential biases in prediction must be addressed to responsibly use MLP in diagnosing mental health disorders.
