Scientists Develop Algorithm for Accurate Financial Time Series Forecasting
Researchers at the HSE Faculty of Computer Science benchmarked more than 200,000 model configurations for predicting financial asset prices and realised volatility, showing that performance can be improved by filtering out noise at specific frequencies in advance. This technique increased accuracy in 65% of cases. The authors also developed their own algorithm, which achieves accuracy comparable to that of the best models while requiring less computational power. The study has been published in Applied Soft Computing.

Full-text Search in Intermediate Data Storage of FCART

.
Neznanov A., Parinov A.

The speed of full-text search directly affects the process of text analysis. Search engine creates a text index, which is used for fast full-text search. Solr and ElasticSearch are two popular search engines. A text analysis system requires fast implementing searching and indexing at the same time. This paper describes preprocessing workflow of the analysis system called Formal Concept Analysis Research Toolbox (FCART) and experiment of searching and indexing social networking service data at the same time. Results of the experiment show which search engine is better as the core of FCART search subsystem.
