Progress with Machine Learning (AI) Seizure Detection Algorithm

I have spent some time over the Christmas break using the data that users have contributed via our Data Sharing (the Open Seizure Database) system.
It looks like I have a model for a single user which detects seizures better than our deterministic algorithm and has a much lower (4.7x) false alarm rate, which is what I was hoping to achieve with a Machine Learning model.

There is a very technical description of the progress for those who are interested here: https://github.com/OpenSeizureDetector/OpenSeizureDatabase/blob/main/Publications/User_Specific_Training_Report_1A.pdf

The next steps are to update the Android App so that it can download different models from our web site and publish that for beta testing.

I will then test the new model to make sure that we have not introduced a lot of other possible false alarm initiators before I train and test it against the whole Open Seizure Database. If that is testing I will make the new version of the app and this model available for all users for testing to see how it performs in the real world.

Release of V1.9 of the Open Seizure Database

Thank you to everyone who is taking part in our Data Sharing (the Open Seizure Database) programme. We now have data from 234 real seizures contributed by users to use to improve Open Seizure Detector.

Real seizure data is very important if we are going to improve OpenSeizureDetector to keep the current very good seizure detection reliability and improve the false alarm rate that we currently see. So please, if you have not signed up to the Data Sharing programme, please consider it (especially if you have regular seizures to help increase the size of the database).

Version 1.9 of the Open Seizure Database is now available for developers or researchers to use to investigate seizure detection methods.

If you would like access to the data to use for research, it is available under a straightforward Licence, so if you get in touch confirming you will agree to the terms of the licence, we will give you access to the full database.

Thanks again to everyone who has contributed data!
