-The data samples used for training corresponds to the period from 1985 and 2013 (both included) and from 2014 to 2017 for per-epoch validation.
+The dataset's temporal division is structured to optimize model training and subsequent per-epoch validation. 
+The training duration spans 29 years, commencing in January 1985 and culminating in December 2013. 
+Sequentially, the validation phase begins, covering the period from January 2014 to December 2017. This 4-year interval is solely dedicated to evaluating the model's 
+aptitude on data it hasn't been exposed to during training. This separation ensures the model's robustness and its capability to make dependable predictions for the 
+validation period.
