Using the features which do not have missing values, we can predict the nulls with the help of a machine learning algorithm. The goal of time series forecasting is to make accurate predictions about the future. Data leakage is when information from outside the training dataset is used to create the model. Datasets may have missing values, and this can cause problems for many machine learning algorithms. As such, it is good practice to identify and replace missing values for each column in your input data prior to modeling your prediction task. Data preparation involves transforming raw data in to a form that can be modeled using machine learning algorithms. Whatever is the reason, missing values affect the performance of the machine learning models. Therefore, in order for machine learning models to interpret these features on the same scale, we need to perform feature scaling. Model-based imputation techniques often outperform model-free methods as imputed values estimated by ML models are often closer to actual values. Machine learning algorithms cannot work with categorical data directly. Missing values are one of the most common problems you can encounter when you try to prepare your data for machine learning.
