In this work we propose a semi-supervised technique for building time series classifiers. While such algorithms are well known in text domains, we will show that special considerations must be made to make them both efficient and effective for the time series domain.

However current research assumes the existence of large amounts of labeled training data. In reality, such data may be very difficult or expensive to obtain. For example, it may require the time and expertise of cardiologists.When dealing with semi-supervised scenarios, the Positive and Unlabeled (PU) problem is a special case in which few labeled examples from a single class of interest are received to proceed with the classification of unseen instances, according to their similarities with the known class.
Both semi-supervised learning and time-series classi cation have been actively researched in the last decades. From the point of view of our current study, most relevant works deal with constrained clustering, cluster-and-label paradigm, self-.
Time Series, Semi-Supervised Learning, Classification 1. INTRODUCTION There has been an enormous interest in time series classification in the last two decades (2)(6)(10). Two related conclusions have begun to emerge as a consensus in the community. First, while there is a plethora of classification algorithms in the literature, the nearest.
Towards a minimum description length based stopping criterion for semi-supervised time series classification.
Time series data with abundant number of zeros are common in many applications, including climate and ecological modeling, disease monitoring, manufacturin A Semi-supervised Framework for Simultaneous Classification and Regression of Zero-Inflated Time Series Data with Application to Precipitation Prediction - IEEE Conference Publication.
In order to construct accurate classifiers, semi-supervised techniques learn both from labeled and unlabeled data. In this paper, we introduce a novel semi-supervised time-series classifier based on constrained hierarchical clustering and dynamic time warping.
The success of semi-supervised learning depends critically on some underlying assumptions. We emphasize the assumptions made by each model and give counterexamples when appropriate to demonstrate the limitations of the different models. In addition, we discuss semi-supervised learning for cognitive psychology.
Self-labeling techniques for semi-supervised time. There are various works in the literature (6,14,44,51,61) that focus on the SSC of time series, which involve self-labeled techniques. Self-training and co-training are the only self-labeled techniques that have been applied in a time series context so far, to the best of our knowledge.

Classification of time series data is an important problem with applications in virtually every scientific endeavor. The large research community working on time series classification has typically used the UCR Archive to test their algorithms. In this work we argue that the availability of this resource has isolated much of the research community from the following reality, labeled time.
Semi-supervised approaches have been developed for time series classification extensively (27) (9). Classification tasks propagate labels to all unlabeled instances of the training data, while.
