Interactive and Robust PCA Graphics with FSDA in MATLAB
Marco Riani, Anthony C. Atkinson, Aldo Corbellini +3
Principal Component Analysis (PCA) is a standard method for dimension reduction and the exploratory analysis of multivariate data, but a complete applied workflow often requires mo…
A practically efficient fixed-pivot selection algorithm and its extensible MATLAB suite
Ivano Azzini, Domenico Perrotta, Francesca Torti
Many statistical problems and applications require repeated computation of order statistics, such as the median, but most statistical and programming environments do not offer in t…
Tk-merge: Computationally Efficient Robust Clustering Under General Assumptions
Luca Insolia, Domenico Perrotta
We address general-shaped clustering problems under very weak parametric assumptions with a two-step hybrid robust clustering algorithm based on trimmed k-means and hierarchical ag…
Like Article, Like Audience: Enforcing Multimodal Correlations for Disinformation Detection
Liesbeth Allein, Marie-Francine Moens, Domenico Perrotta
User-generated content (e.g., tweets and profile descriptions) and shared content between users (e.g., news articles) reflect a user's online identity. This paper investigates whet…
Robust Monitoring of Time Series with Application to Fraud Detection
Peter J. Rousseeuw, Domenico Perrotta, Marco Riani +1
Time series often contain outliers and level shifts or structural changes. These unexpected events are of the utmost importance in fraud detection, as they may pinpoint suspicious…
A Parametric Framework for the Comparison of Methods of Very Robust Regression
Marco Riani, Anthony C. Atkinson, Domenico Perrotta
There are several methods for obtaining very robust estimates of regression parameters that asymptotically resist 50% of outliers in the data. Differences in the behaviour of these…
