ScalaAnalytics Weather Prediction

Data Model

  • 10 year long weather data of Seoul (Sep 7th, 2007~ Sep 7th, 2017)
  • 7 year long data is separated for training and the rest 3 year data is used for testing

Network Model

  • Keras regression model (Tensorflow backend)
  • Training epochs : 200
  • batch size : 32
  • optimizer : adam.
    • Comments : The input dimension is 43.
      We eliminated blank data from the dataset we downloaded.
      We still found blank data in some of its training set and filled them with mean values.
      I guess the prediction errors on highest temperature prediction are caused by those blank data.
      Except those errors, mean accuracy is almost +- 0.5 norm. Celcius.

ScalaAnalytics Epileptic Seizure Prediction

Data Model : Qiuyi Wu (qw9477'@'rit.edu) and Ernest Fokoue (epfeqa'@'rit.edu) of School of Mathematical Sciences, Rochester Institute of Technology, NY, U.S.A. (Date Donated: May 24th, 2017).

Network Model

  • Keras regression model (Tensorflow backend)
  • Training epochs : 120
  • batch size : 64
  • Results The accuracy is almost 97.7% and loss is 0.0768
This dataset has 5 classes:
  1. Having an epileptic seizure
  2. They recorder the EEG from the area where the tumor was located
  3. They identify where the region of the tumor was in the brain and recording the EEG activity from the healthy brain area
  4. eyes closed, means when they were recording the EEG signal the patient had their eyes closed
  5. eyes open, means when they were recording the EEG signal of the brain the patient had their eyes open
