学位论文简介

Due to today’s transition to online shopping in the last few decades, predicting product prices of e-commerce is gaining importance. Likewise, commodity prices are a significant factor for mining projects, as price volatility is an important parameter for mining company evaluation and investment decision making. In this work, we propose four contributions (i.e., prediction models) to address four price prediction problems using statistical, machine learning and deep learning methods.  We utilized several algorithms from each domain.

The first two contributions address the price prediction problem of e-commerce products to fill in the gap of the current price prediction models for addressing second-hand items of e-commerce products.

The third and fourth contributions are introduced for addressing price forecasting of two vital energy markets, i.e., coal and oil markets using hybrid deep learning and ensemble learning methods, respectively.

In summary, the results demonstrate the superiority of the proposed methods over the baseline models. All the proposed methods lead to performance improvement.
