Many powerful anomaly detection algorithms are based on machinelearning and rely on datasets for training and evaluation. However, anomalous samples are often rare in real-world datasets and might not be representative of anomalies encountered in the field. In this paper, we propose a synthetic anomaly generation methodology that focuses on generating large numbers of synthetic anomalies in images with defined variances in size, shape, and texture, achieving higher diversity scores than the state-of-the-art. To demonstrate the value of the proposed generation methodology for in-depth performance analysis, we generate anomalies in three MVTec AD datasets, which we then use to analyze and evaluate several anomaly detection algorithms. While all analyzed anomaly detection algorithms showed strong recall rates on these datasets, significant sensitivity differences regarding an anomaly's size, shape, and texture are observable through the analysis with our synthetic datasets. While we observed some algorithms' robustness towards different anomaly shapes and textures, others showed differences in recall rates of up to 80% points for some pixel manipulation methods. the results demonstrate the value of our synthetic anomalies, as they boost the capability to scrutinize anomaly detection algorithms.

Parkinson's disease is a common neurological condition that occurs when dopamine production in the brain decreases significantly due to the degeneration of neurons in an area called the substantia nigra. One of its characteristics is the slow and gradual onset of symptoms, which are varied and include tremors at rest, rigidity, and slow speech. Voice changes are very common among patients, so analysis of voice recordings could be a valuable tool for early diagnosis of the disease. this study proposes an approach that compares different machinelearning models for the diagnosis of the disease through the use of vocal recordings of the vowel a made by both healthy and sick patients and the identification of the subset of the most significant features the experiments were conducted on a data set available on the UCI repository, which collects 756 different recordings. the results obtained are very encouraging, reaching an F-score of 95%, which demonstrates the effectiveness of the proposed approach.
