Investment funds management strategy based on polynomial regression in machine learning

A. Wiliński, A. Smoliński, W. Nowicki Intelligent Systems for Computer Modelling: Proceedings of the 1st European-Middle Asian Conference on Computer Modelling 2015, EMACOM 2015 This paper presents the results of an investment strategy simulation. The strategy is based on common regression models in a time series, which yields the decision. A simple polynomial regression was the basic method used to achieve short-term value forecasts in the time series. Base params (number of steps in the past and a degree of a polynomial) were set based on a machine learning algorithm. The strategy is improved with some additional original (constitutes by the authors) parameters because using only the regression proved to be completely ineffective. Financial markets with bidirectional transactions (long and short transactions), as well as only long transaction markets, were both taken under research. on-line

Process of market strategy optimization using distributed computing systems

Management and Production Engineering Review, volume 6, number 4, December 2015
If market repeatability is assumed, it is possible with some real probability to deduct short term market changes by making some calculations. The algorithm, based on logical and statistically reasonable scheme to make decisions about opening or closing position on a market, is called an automated strategy. Due to market volatility, all parameters are changing from time to time, so there is need to constantly optimize them. This article describes a team organization process when researching market strategies. Individual team members are merged into small groups, according to their responsibilities. The team members perform data processing tasks through a cascade organization, providing solutions to speed up work related to the use of remote computing resources. They also work out how to store results in a suitable way, according to the type of task, and facilitate the publication of a large amount of results. Read Article

Study on the Effectiveness of the Investment Strategy Based on a Classifier with Rules Adapted by Machine Learning

ISRN Artificial Intelligence, Vol. 2014
Paper examines two transactional strategies based on the classifier which opens positions using some rules and closes them using different rules. A rule set contains time-varying parameters that when matched allow to make an investment decision. Researches contain the study of variability of these parameters and the relationship between learning period and testing (using the learned parameters). The strategies are evaluated based on the time series of cumulative profit achieved in the test periods. The study was conducted on the most popular currency pair EURUSD (Euro - Dollar) sampled with interval of 1 hour. An important contribution to the theory of algotrading resulting from presented research is specification of the parameter space (quite large, consisting of 11 parameters) that achieves very good results using cross validation.

Meaning of simple rules in investment strategies of algorithmic trading

In article are shown studies of the possibly simplest investment strategy of algo trading. The authors’ intention was to prove the thesis that in the greedy algorithmic trading directed to the proper response, not to forecast, there are almost always opportunities to achieve profit. This paper presents the results of tests for over twenty core markets - currency pairs, indices and commodities (eight results included). Introduced the original concept of quadrant of openings on each bar. In principle, the strategy is not relevant investment (studies were conducted without transaction costs), only cognitive in order to develop.

In the article the problem of visual gesture recognition for presentation steering is presented. Based on camera image analysis the idea of steering is proposed. Presented system operates without a specialized controller and bases on visual gestures of the presenter. Conducted experiments with users demonstrated high usability of the system.
