Jun 23, 2020 · We are tracking data from past 720 timestamps (720/6=120 hours). This data will be used to predict the temperature after 72 timestamps (72/6=12 hours). Since every feature has values with varying ranges, we do normalization to confine feature values to a range of [0, 1] before training a neural network.
