WebAug 30, 2024 · So, I create a helper function, create_dataset, to reshape the input. In this project, I define look_back = 30. It means that the model makes predictions based on the last 30-day data (In the first iteration of the for-loop, the input carries the first 30 days and the output is water consumption on the 30th day). WebThis is a part of data management. Data sets describe values for each variable for unknown quantities such as height, weight, temperature, volume, etc., of an object or values of random numbers. The values in this set are known as a datum. The data set consists of data of one or more members corresponding to each row.
