Dimensionality reduction techniques are often used by researchers in order to make high dimensional data easier to interpret visually, as data visualization is only possible in low dimensional spaces. Recent research in nonlinear dimensionality reduction introduced many effective algorithms, including t-distributed stochastic neighbor embedding (t-SNE), uniform manifold approximation and projection (UMAP), dimensionality reduction technique based on triplet constraints (TriMAP), and pairwise controlled manifold approximation (PaCMAP), aimed to preserve both the local and global structure of high dimensional data while reducing the dimensionality. The UMAP algorithm has found its application in bioinformatics, genetics, genomics, and has been widely used to improve the accuracy of other machine learning algorithms.

This paper reviews the use of psychotherapeutic approaches to treat individuals who have committed sex crimes and/or have problematic sexual interests (PSI); including types of psychotherapy used, descriptions of preventive and reintegration programmes, and highlighting specific theoretical controversies. In the second part, experts from Canada, the Czech Republic, Russia, the United Kingdom, and the United States, who participated in an International Consensus Meeting held in Prague (2017), summarize treatment programmes in their countries. The comparison revealed some general findings: each country has variability between its own programmes; most countries have different programmes for people who are in custody and who are in the community; the state-directed treatment programmes are primarily focused on criminal individuals, while non-criminal individuals are treated in preventive programmes and/or in special clinics or are untreated; the presence of PSI in patients is acknowledged in most programmes, although specific programmes exclusively for individuals with PSI rarely exist.

This article provides a comparison and comprehensive analysis of varied approaches to the assessment of sexual interest and behaviours at different international sexual behaviour assessment labs. The assessment protocols are described for four sexual behaviour laboratories: the Royal Ottawa Mental Health Centre's Sexual Behaviours Clinic in Canada; the Medical University of South Carolina's Sexual Behaviours Clinic and Laboratory in the US; the Laboratory of Evolutionary Sexology and Psychopathology in the Czech Republic; and the Laboratory of Forensic Sexology in Russia. An overview of examinee demographics and types of cases assessed is provided for each lab.

Aim: To consider the patterns of stimuli analysis and task execution in conditions of voluntary and involuntary attention in people with schizotypal disorder from the psychopathological and psychological points of view.

Material And Methods: A total of 40 subjects were examined including 16 patients diagnosed with schizotypal disorder, 13 with personality disorders and 11 without psychiatric pathology (controls). In the first part of the study, subjects looked upon various static images without any instructions, followed by a test with antisaccade task in vertical and horizontal directions; the last task duplicated the first, but the subjects were asked to remember the presented images as best as possible.
