Many real-world applications require prediction that takes the most advantage of data. Classic data mining mechanisms tend to feed a prediction model pivotal data to achieve a promising result, which needs to be adjusted in different application scenarios. Recent studies have shown the potential of I Ching mechanism to improve prediction capacity. However, the I Ching prediction mechanism has several issues, including underutilized I Ching knowledge and incomplete data conversion. To address these issues, the authors designed a model to leverage I Ching knowledge and transform traditional I Ching prediction processing into data mining. The authors' investigation revealed promising results in the stock market compared to popular machine learning and deep learning algorithms such as support vector machine (SVM), extreme gradient boosting (XGBoost), and long short-term memory (LSTM).

Recently, machine learning techniques, especially supervised learning techniques, have been adopted in the Intrusion Detection System (IDS). Due to the limit of supervised learning, most state-of-the-art IDSs do not perform well on unknown attacks and incur high computational overhead in the Internet of Things (IoT). To overcome these challenges, we propose a novel IDS based on unsupervised techniques, namely, UTEN-IDS. UTEN-IDS uses the ensemble of autoencoders to handle the network data and performs the anomaly detection by an Isolation Forest algorithm. The effectiveness of the proposed method is verified using two benchmark datasets. The results show that our approach has significant advantages in classification performance and proves its utility in the IoT network when compared to other approaches. [ABSTRACT FROM AUTHOR]
