Probabilistic Machine Learning for Circular Statistics: Models and inference using the Multivariate Generalised von Mises distribution
Probabilistic machine learning and circular statistics—the branch of statistics concerned with data as angles and directions—are two research communities that have grown mostly in isolation from one another. On the one hand, probabilistic machine learning community has developed powerful frameworks …

Feature extraction and matching of palmprints using level I detail
… techniques, based upon the novel use of local circular statistics on palmar orientation fields. In combination, these techniques are shown to provide a more accurate orientation estimate than previous work. The novel feature extraction stages exploit the level sets of higher order local …

“With a Little Help from My Friends”: The Influence of Co-offenders on the Journey to Crime
… with a co-offender. Descriptive and inferential circular statistics as well as Euclidean distance metrics are employed to highlight the journey to crime differences when individuals commit solo vs. co-offenses across different crime types. Broadly, the research found no significant differences in …

Modeling the diameter and locational distributions of branches within the crowns of loblolly pine trees
… describe the diameter distribution of branches. Circular statistics were used to examine branching patterns around the bole. A recursive system of 2 equations was developed in order to predict the total number of branches within a crown. A series of 3 equations was used to describe the average of …

Interaction in musical time
… individuals. I discuss a range of options from circular statistics to cross-recurrence analysis to various correlation-based analyses. Through a number of pilot studies, I developed a cooperative tapping setup for studying rhythmic entrainment in dyads. Using this setup, I compared human–human …

Variação no padrão de atividade de mamíferos em resposta à sazonalidade em um parque nacional da floresta tropical seca brasileira
… camera-days, respectively. Rarefaction curves, circular statistics, and occupancy models were some of the analyses used to characterize the assemblage and its seasonal patterns. We obtained 485 records of 11 species of mammals distributed in six orders and nine families, including two species …

Mathematical Modeling of Circadian Gene Expression in Mammalian Cells
… two methods tailored for the calculation of circular Sobol indices. In the first project, we modified the core negative feedback loop in a mathematical model of the mammalian genetic oscillator so that the unrealistic tight binding between the repressor PER and the activator BMAL1 is relaxed …

Predictability and trends of annual pollutant loads in Midwestern watersheds
… export from large Midwestern watersheds using circular statistics. This enables identification of critical periods of high load export and also gaging impacts of landuse, management practices, and sources of pollution on overall annual loads. These analyses constitute the first such application …

Crustal stress variability across spatial scales - examples from Canada, Northern Switzerland and a South African gold mine
The quantitative descriptions of the state of stress in the Earth’s crust, and spatial-temporal stress changes are of great importance in terms of scientific questions as well as applied geotechnical issues. Human activities in the underground (boreholes, tunnels, caverns, reservoir management, …
