Step 3 - Loading and parsing the training and test set

Now let's load the dataset. I am assuming that you copied your dataset to the UCI_HAR_Dataset/ directory. Then, also place the other data files as described previously:

val datasetPath = "UCI_HAR_Dataset/" 
val trainDataPath = s"$datasetPath/train/Inertial Signals" 
val trainLabelPath = s"$datasetPath/train/y_train.txt" val testDataPath = s"$datasetPath/test/Inertial Signals" 
val testLabelPath = s"$datasetPath/test/y_test.txt" 

Now it's time to load the training and test set separately. To do this I wrote two methods called loadData() and loadLabels() that are in the Utils.scala file. These two methods and their signatures will be provided soon:

val trainData = Utils.loadData(trainDataPath, ...
