    Overview of the Task: The original test sheets contain many data sets each with 49 numbers. Each data set is a column. Each of the data sets/columns has 7 out of 49 numbers selected as Process numbers. These are given in bold red. Now, the last column, the rightmost column, is the target data set for prediction. All other columns are data sets to be used for training the model. The project's ultimate objective is to predict the 7 process numbers of that last column/data set using Machine Learning models. We are using as many as 5 different types of ML models to predict these 7 pattern numbers from the target data set which is the last column of each test sheet. During this process of prediction, we have come across certain observations. We had to solve those observations and imp...
