Symmetric data should look nearly identical if folded in half at the center point of the distribution. Data that is symmetrical and unimodal is often described as normal, which is important for checking assumptions of WebThe key to building a good machine learning model is the data it is trained on. Therefore it is imperative that the training data be clean and balanced. The more time you spend on perfecting your training data, the less efforts you’ll need to spend on your model.
