How do we determine current values and estimated future values?

BrickEconomy price estimation is based on Artificial Intelligence (AI) via Machine Learning (ML) to provide an accurate estimated and predicted price of every new/sealed set and minifig. Currently, when you look at the current value of a set or minifig or an estimated future price prediction this data is based on our machine learning technology. It's not only very cool, but it is extremely accurate! We use a variety of algorithms to train our ML predictions but typically rely on neural network regression and linear regression models. Additionaly we are contstantly re-training our models and have various ones for sets and minifigs. Even cooler, our machine learning model can even predict future gains for newly released sets at an 89% accuracy rate!
