I understand that you want to use only one signal as input to a sequence-to-sequence learning model for classification.
Yes, it is possible. In fact, this is a common approach for many sequence classification tasks, such as text classification and speech recognition, you can follow these steps:
- Prepare the data: Convert the error signal into a sequence of tokens.
- Design the model: Choose a sequence-to-sequence learning model architecture, such as a recurrent neural network (RNN) or a long short-term memory (LSTM) network. The model should have an input layer that accepts sequences of tokens and an output layer that predicts the class label.
- Train the model: Train the model on the prepared data.
- Evaluate the model: Evaluate the model on a held-out test set.
Once the model is trained and evaluated, you can use it to classify new error signals into the three classes.
