Machine Learning Models Can Help Reduce Volatility and Boost Stock Market Returns

The use of machine learning models makes it possible to achieve greater accuracy in predicting risks in the Russian stock market compared to classical econometric approaches. The predictive power of these models increases by 23%, while the average investor’s return can reach up to 13% per annum. These conclusions were drawn by Nikita Lysenok from the Department of Financial Market Infrastructure at the HSE Faculty of Economic Sciences. The paper has been published in Fundamental and Applied Mathematics.

Pocket Money, Personal Interest, and Family Practices: What Shapes Students Economic Literacy?

University students' economic literacy depends not only on their field of study but also on their interest in economics, the learning environment, and family financial practices. For example, students who received pocket money irregularly tend to perform better on economic literacy tests than their peers who received financial support on a regular basis. These findings come from a study conducted by HSE University involving more than 1,100 students from five Russian universities. The findings have been published in Cakrawala Pendidikan.

Creative Work as a Remedy for Burnout

The creative, supportive atmosphere and innovative methods at the Centre for Sociocultural Research make it appealing to early-career scholars. Over years of working at HSE University, they grow into researchers and lecturers recognised both in Russia and abroad. Chief Research Fellow Zarina Lepshokova and Leading Research Fellow Ekaterina Bushina spoke about their journey at the centre and at HSE, their research, and the role of mentors in their academic success.

A transmission system with a hybrid automatic repeat request is considered in the presence of slow Rayleigh fading. A technique is described for finding an upper estimation of the spectral efficiency for such a system with a restriction on the type of modulation. Estimation can be used in the analysis of developed and existing feedback transmission systems.

Об оценках сложности схем в одном бесконечном базисе

Podolskaya O., В кн.: Материалы IX молодежной научной школы по дискретной математике и ее приложениям (Москва, 16-21 сентября 2013 г.).: М.: Издательство ИПМ РАН, 2013. С. 97–100.

We study Boolean circuit complexity in an infinite basis consisting of all Boolean functions that equal 1 only on sets of pair-wise incomparable tuples. It is known that lower bounds on the complexity of linear function, majority function and almost all boolean functions of $n$ variables are of the order $\sqrt n.$ We show that ...
