Project goal : The main problem with this data was the big variance in prices between different car models. as an example there is a cheap model that ranges between 10k to 20k while there are expensive models that range between 100k and 150k. https://www.kaggle.com/enginsights/audi-preprocessing-and-exploration Solution: As a result, we had to clean data based on models so that every model has a unique standard deviation to let the training process work properly and not be manipulated by outliers. We calculated the standard deviation of prices for each model and we took from -2 to 2 standard deviations so that we had 95% of the middle prices and we removed 5% outliers.
