ECOD: Unsupervised Outlier Detection Using Empirical Cumulative Distribution Functions

2 code implementations2 Jan 2022 Zheng Li, Yue Zhao, Xiyang Hu, Nicola Botta, Cezar Ionescu, George H. Chen

To address these issues, we present a simple yet effective algorithm called ECOD (Empirical-Cumulative-distribution-based Outlier Detection), which is inspired by the fact that outliers are often the "rare events" that appear in the tails of a distribution.

COPOD: Copula-Based Outlier Detection

3 code implementations20 Sep 2020 Zheng Li, Yue Zhao, Nicola Botta, Cezar Ionescu, Xiyang Hu

In this work, we make three key contributions, 1) propose a novel, parameter-free outlier detection algorithm with both great performance and interpretability, 2) perform extensive experiments on 30 benchmark datasets to show that COPOD outperforms in most cases and is also one of the fastest algorithms, and 3) release an easy-to-use Python implementation for reproducibility.

Domain-Specific Languages of Mathematics: Presenting Mathematical Analysis Using Functional Programming

1 code implementation29 Nov 2016 Cezar Ionescu, Patrik Jansson

We present the approach underlying a course on "Domain-Specific Languages of Mathematics", currently being developed at Chalmers in response to difficulties faced by third-year students in learning and applying classical mathematics (mainly real and complex analysis).
