    Still to distinguish each value from different features, it proposes to add a different constant to values coming from different features, so values from one feature will be in one particular range and values from other features will not be in that range. For example, say we have 3 features to combine and all are between 0–100. So, we will add 100 to second feature and 200 to third feature
