To implement fault detection in a chemical process using deep learning in MATLAB, you can follow these steps:
Data collection: Collect data from sensors installed in the chemical process. The dataset should contain both normal and abnormal operating conditions.
Data pre-processing: Pre-process the dataset using methods like normalization, standardization, filtering, and feature extraction. This step is crucial as the neural network's performance depends on the quality of data.
Feature selection: Select the most relevant features from the pre-processed dataset. This step helps to reduce the input dimensionality and improve the neural network's performance.
Neural network architecture design: Design a neural network architecture depending on the complexity of the problem. You can use autoencoders, convolutional neural networks (CNN), recurrent neural networks (RNN), or a combination of these architectures.
Training the model: Train the neural network model using the pre-processed dataset. Specify the optimization algorithm, batch size, epochs, and other relevant parameters.
Validation and testing: Validate the neural network model using a validation set to check if the model is not overfitting. Assess the model's performance using the suitable metrics like accuracy, recall, F1-score, and confusion matrix. Test the model on newly collected data to verify its reliability.
Here's an example of building a deep learning model for fault detection in a chemical process using MATLAB:

In this example, we used a multi-layer perceptron network (MLP) for fault detection in a chemical process. You can experiment with other neural network architectures or tune hyperparameters to enhance its performance.
