I need help to design a supervised-training classifier in Matlab. I have the Deep Learning Toolbox and the Statistics and Machine Learning Toolbox available. I need to train a network to classify feature vectors where each vector represents a discrete-time signal of a physiological reflex response to a stimulus. Each 1x180 vector maps a baseline value, followed by the response to stimulus and recovery back toward the baseline. Please see the attached image of a plot of a typical vector, where the red line marks the stimulus. A certain disease condition causes characteristic changes to this reflex. The presence of this condition affects the shape of the vector plot as seen in the figure, in terms of amplitude, initial response time, speed of change in the initial response and/or recovery phase, and other small changes to specific areas of the plot. Given a reflex feature vector, I need to predict when this condition is present. The network I'm asking you to design will be trained with feature vectors labeled in a binary manner to indicate only if the particular condition is present or not. Training data consists of a set of 1x180 feature vectors each associated with one of two labels (indicating "present" and "not present"). Each value in the vector is a number ranging between 1 and 8 with 0-4 decimal places, and some values may be NaN. Input to trained network is a vector of the type supplied for training. Output of trained network should be a prediction for each label, e.g., PRESENT 92%, NOT PRESENT 8%. Deliverables in order: 1) Your proposal for the classifier's design. This is just expected to be a short piece of writing; a few paragraphs should suffice. (A network diagram would also be helpful but not required if the proposal is sufficiently detailed.) I think LSTM networks look like a good possible choice for this task, but you are an expert and I want to leverage your expertise. I want to know your network choice and your arguments for using this particular type of network for my requirements. In your proposal, specify the different layers of the network and their functions, so I can understand your reasoning. I want to understand and approve of the design before you implement it. 2) Matlab code to set up classifier + sample code for training and using it. This code should implement the network design that we agree upon. It should be able to import training data from text files, and the trained classifier must be able to be run as a stand-alone Matlab file or embedded into other Matlab scripts.

Greetings, I am please to let you know that I am an professional Machine Learning, Deep Learning and Neural Networking expert with over 6 years of experience in the field. As far as I understood from your project description its a deep learning classifier project with 180 features. You may expect an accuracy rate of over 90% as per the training and the test data set, though I would like to have a look at a sample data before assuring it. As far as the model is concerned, we are looking at sequential data with temporal dynamics connecting the data holding much more importance than the spatial content of each individual frame. So I suggest we do the RNN/LSTM model approach because that would produce predictive results in sequential data that other other algorithms can't. I could explain further but I guess its best we discuss further in the chat. Please let me know. Thank you.

I am a graduate engineering student and a freelance machine learning engineer. I have worked on several machine learning projects recently such as: - Stock market index forecasting using neural network ensembles. - Prediction of the place of the next terrorist attack in the Middle East using global terrorism database. - Implementation of face recognition algorithms - Classification of experienced/inexperienced welding operators. I think it would be best to start simple with our choice of algorithm instead of going for LSTM directly. The number of parameters in a typical LSTM is pretty high and I think it should be used only when necessity arises. I suggest using SVM, MLP and decision tree based ensemble algorithms first. Let me know if you are interested. Best Regards, Koray

I have already done my research work for the similar task during my PhD. I have used appropriate feature vector and based on it, using SVM classified the data. For your need, i think SVM will work, Further, in Machine learning based approach, in the work flow based on available known data training can be done then after classifier model will do the classification. Choice of feature vector depends on data. Choice of ML or DL also depends on how much data is available. I have more than 15 years of teaching and research experience and guiding PhD students also.
