This paper presents a state-of-the-art solution to the LT-EDI-ACL 2022 Task 4: Detecting Signs of Depression from Social Media Text. The goal this task is detect severity levels depression people social media posts, where often share their feelings on daily basis. To signs depression, we propose framework with pre-trained language models using rich information instead training scratch, gradient boosting and deep learning for modeling various aspects, supervised contrastive generalization...

The size of the population can be critical in many application genetic algorithm. And probabilities crossover and mutation have an effect on diversity convergence In this paper we propose adaptive method for probabilities, which change with varying size. This algorithm could make great progress searching global optimization. experimental results indicate some merits proposed method.

Most existing risk prediction methods focus on constructing element sets and analyzing their uncertainties but do not deeply explore the correlation types intensities of factors, resulting in large errors comprehensive results. In this paper, a new integrated method is proposed based tasks defense task planning execution. The approach mainly includes following steps: First, difference sequence mode action link tasks, three (hierarchical, synergistic, independent) are defined among them,...

Self-supervised learning (SSL) has been incorporated into many state-of-the-art models in various domains, where SSL defines pretext tasks based on unlabeled datasets to learn contextualized and robust representations. Recently, a new trend exploring the representation capability realm of tabular data, which is more challenging due not having explicit relations for descriptive This survey aims systematically review summarize recent progress challenges non-sequential data (SSL4NS-TD). We...

The marketplace system connecting demands and supplies has been explored to develop unbiased decision-making in valuing properties. Real estate appraisal serves as one of the high-cost property valuation tasks for financial institutions since it requires domain experts appraise estimation based on corresponding knowledge judgment market. Existing automated models reducing subjectivity require a large number transactions effective evaluation, which is predominantly limited not only labeling...

The partial and complete periodic synchronization in coupled discontinuous map lattices consisting of both non-invertible maps are discussed. We classify three typical types states, which give rise to different spatiotemporal patterns including static synchronization, dynamically patterns. A special prelude dynamics motion, is shown by five separated concave curves the time series plots order parameters, observed. detailed analysis shows that induced competition between two synchronized...
