Classification of time series has received an important amount of interest over the past years due to many real-life applications, such as environmental modeling, speech recognition, and computer vision.
In my thesis, I focus on classification of time series by LVQ classifiers. To learn a classifiers, we need a training set. In our case, every data point in the training set contains a sequence (an ordered set) of feature vectors. Thus, the first task is to construct a new feature vector (or matrix) for each sequence.
Inspired by [2], I use Hankel matrices to construct the new feature vectors. This choice comes from a basic assumption that each time series is generated by a single or a set of unknown Linear Time Invariant (LTI) systems.
After generating new feature vectors by Hankel matrices, I use two approaches to learn a classifier: Generalized Learning Vector Quntization (GLVQ) and Median variant of Generalized Learning Vector Quantization (mGLVQ).
Genetic sex determination of ancient DNA samples based on one simple mathematical algorithm, which considers the number of mapped reads on autosomal, X, and Y chromosomes. The algorithm is implemented in one command line tool - SiD. SiD is used to deter-mine the sex of 16 samples, which have been shotgun sequenced and captured with a 1240k panel.
