Variable Selection in Switching Dynamic Regression Models

Complex dynamic phenomena in which dynamics is related to events (modes) that cause structural changes over time, are well described by the switching linear dynamical system (SLDS). We extend the SLDS by allowing the measurement noise to be mode-specific, a flexible way to model non stationary data. Additionally, for models that are functions of explanatory variables, we adapt a variable selection method to identify which of them are significant in each mode. Our proposed model is a flexible Bayesian nonparametric model that allows to learn about the number of modes and their location, and within each mode, it identifies the significant variables and estimates the regression coefficients. The model performance is evaluated by simulation and two application examples from a dataset of meteorological time series of Barranquilla, Colombia are presented.

A Pilot on the Use of Unsupervised Learning and Probabilistic Modelling Towards Cancer Extent Prediction

Cervical cancer is a global disease that attacks the female reproductive system and remains challenging to diagnose in the early stages. The rise in the application of machine learning models in various aspects of clinical medicine has seen research an increase in research applied toward the diagnosis of cervical cancer using a questionnaire style format. This work explores the application of unsupervised learning for an automated partitioning and learning of class labels, followed by subsequent learning of the designated labels using a supervised learning method. A contrast was conducted between two unsupervised learning methods, namely the agglomerative hierarchical clustering and k-means, where it was seen the k-means provided superior and more accurate clustering capabilities. The labels provided by the k-means were used to train the naïve Bayes (NB) classifier, which is capable of outputting probabilities associated with class predictions, therein allowing for the stage of cancer to be inferred. The results from the NB showed high accuracies in the region of 90+% across the various classifier metrics, therein showing good learning capability for learning from clustered data. The study provides evidence to show that a fully automated platform, which utilizes questionnaire style information, can predict whether a patient has cervical cancer alongside the likely cancer extent. Future work would now involve the use of a rule-based inference system that can automatically provide clinicians with a cancer extent where necessary and is also capable of handling further cancer stage subclasses information.

Dispersion of Trace Elements as Consequence of insitu Weathering in granite-derived Tropical Soils in Southwestern Nigeria

Trace elements composition of granite and tropical soils formed by in-situ weathering over the basement complex of Ikere-Ekiti, Ado-Ekiti and Igbrara-Odo areas of SW Nigeria is evaluated and reported. The granitoids exhibit chemical features such as is common to other granite bodies across the basement areas. The soil profiles typically have four different horizons with contrasting physical characteristics. Analytical result from ICP-MS technique revealed compositional variation along vertical direction within depth of the profiles. Trace element as average for the granite reveals low Tm (0.5 ppm), Eu (2.1 ppm), Co (5.1 ppm), Sc (7.2 ppm), Hf (7.6 ppm), Sm (12.6 ppm), and Th (30.5 ppm) values, while La (110 ppm), Ce (216 ppm), Cr (235.5 ppm), and Ba (963 ppm) show enrichments. All the soils have Sm, Eu, Th, Hf and Co contents below 10 ppm; Sc, La and Ce values fall between 10-100 ppm, while Cr and Ba contents fall between 200-1500 ppm. Variation between trace contents in granite and the derived soils as revealed along depths of the profile indicates greater mobility of Th, Sc and Ba during chemical weathering while Eu and Tm are least mobile. Pronounced compositional variation occur at relatively shallow (0-1m) depth in near surface area all the profiles.
