We show that in pool-based active classification without assumptions on the underlying distribution, if the learner is given the power to abstain from some predictions by paying the price marginally smaller than the average loss 1/2 of a random guess, exponential savings in the number of label requests are possible whenever they are possible in ...

Active Learning for Sequence Tagging with Deep Pre-trained Models and Bayesian Uncertainty Estimates
, , et al., , in: Proceedings of the 16th Conference of the European Chapter of the Association for Computational Linguistics. Vol. 16.: Association for Computational Linguistics, 2021.. P. 1698 1712-1712.
Annotating training data for sequence tagging of texts is usually very time-consuming. Recent advances in transfer learning for natural language processing in conjunction with active learning open the possibility to significantly reduce the necessary annotation budget. We are the first to thoroughly investigate this powerful combination for the sequence tagging task. We conduct an extensive ...

In the present study, I use large-scale survey data to compare radical right voting to other forms of electoral behavior in Western Europe. The chosen method, multilevel multinomial logistic regression, allows, first, distinguishing among voting for several party families as well as abstention and, second, controlling for differences between countries and survey rounds. I find ...

Humans can adapt their behavior by learning from the consequences of their own actions or by observing others. Gradual active learning of action-outcome contingencies is accompanied by a shift from feedback- to response-based performance monitoring. This shift is reflected by complementary learning-related changes of two ACC-driven ERP components, the feedback-related negativity (FRN) and the error-related ...

Computer simulation, an active learning technique, is now one of the advanced pedagogical technologies. The use of simulation games in the educational process allows students to gain a firsthand understanding of the processes of real life. Public administration, public policy, and political science courses increasingly adopt simulation games in universities worldwide. Besides person-to-person simulation games, ...

Одним из хорошо обоснованных в литературе приемов обучения является сравнение двух аналогичных учебных задач, проясняющее их структуру и облегчающее дальнейший перенос способа решения в новый контекст. К сожалению, подбор правильных задач для сравнительного изучения часто становится отдельной методической проблемой. Альтернативой могла бы стать инструкция на самостоятельное выведение принципа из единственной учебной задачи, но эффект такой инструкции мало изучен. ...

In this paper, we report on the results of an experiment in teaching discrete mathematics to students majoring in business informatics. We supplemented our problem-based approach to teaching the course with a set of Likert-scale surveys or questionnaires that helped improve the students’ performance. On the one hand, these surveys gave us feedback and, on ...

Global sensitivity analysis aims at quantifying respective effects of input random variables (or combinations thereof) onto variance of a physical or mathematical model response. Among the abundant literature on sensitivity measures, Sobol indices have received much attention since they provide accurate information for most of models. We consider a problem of experimental design points selection ...

Active learning (AL) is a prominent technique for reducing the annotation effort required for training machine learning models. Deep learning offers a solution for several essential obstacles to deploying AL in practice but introduces many others. One of such problems is the excessive computational resources required to train an acquisition model and estimate its uncertainty ...

We consider a problem of adaptive design of experiments for Gaussian process regression. We introduce a Bayesian framework, which provides theoretical justification for some well-know heuristic criteria from the literature and also gives an opportunity to derive some new criteria. We also perform testing of methods in question on a big set of multidimensional functions. ...

Modern supervised algorithms assume that the dataset used for training has the same distributions as the data to be processed. However, the real data is permanently changing. This leads to the gradual degradation of supervised machine learning algorithms in production systems and increases the cost of the maintaining. To solve this problem, we are focusing ...
