Format of files to be submitted:
\r\n.csv file with columns: 'file' (from 1 to 3481) and 'activity' (from 1 to 6). Each row should be presented like '3408, 6'. This means that sequence in file '3408.csv' corresponds to activity #6.

Already today, they can keep track of our activities, learn from them, and subsequently help us make better decisions in the future, the abilities of great importance, e.g., for development of new sports mobile apps. However, for this potential to be realized, we have to be able to process the incoming information from smartphone's sensors and identify types of activities corresponding to different patterns in sensor data.
\r\n1. Create a recurrent neural network that takes data from sensors as input and predicts the type of the current activity (from 1 to 6).
2. Assignment will be considered as successfully completed if accuracy on the test set is greater than 78%
Train and test datasets for this assignment were prepared based on the Human Activity Recognition with Smartphones datasets available on Kaggle. The original experiments have been carried out with a group of 30 volunteers. Each person performed six activities (WALKING, WALKING_UPSTAIRS, WALKING_DOWNSTAIRS, SITTING, STANDING, LAYING) wearing a smartphone (Samsung Galaxy S II) on the waist. Using its embedded accelerometer and gyroscope, 3-axial linear acceleration and 3-axial angular velocity were captured at a constant rate of 50Hz. The sensor signals (accelerometer and gyroscope) were pre-processed by applying noise filters and then sampled in fixed-width sliding windows of 2.56 sec and 50% overlap (128 readings/window).
\r\nEach input time series in our datasets is composed of 5 timesteps and includes only mean values from accelerometer and gyroscope. We also have introduced some additional noise to the original data in order to prevent students from training their models with datasets augmented by publicly available test data.
\r\n1. Training dataset consists of 3599 time series each of which is assigned to one of 6 classes. We have already divided training dataset into train and validation parts, but feel free to make your own division.
2.Test dataset is composed of 3481 not labeled time series
