Mass appraisal of residential apartments: An application of Random forest for valuation and a CART-based approach for model diagnostics
To the best knowledge of authors, the use of Random forest as a potential technique for residential estate mass appraisal has been attempted for the first time. In the empirical study using data on residential apartments the method performed better than such techniques as CHAID, CART, KNN, multiple regression analysis, Artificial Neural Networks (MLP and RBF) and Boosted Trees. An approach for automatic detection of segments where a model significantly underperforms and for detecting segments with systematically under- or overestimated prediction is introduced. This segmentational approach is applicable to various expert systems including, but not limited to, those used for the mass appraisal.
This article examines the position of Russian state courts, in particular, of the Supreme Commercial Court, w i t h regard to the arbitrability of disputes concerning the transfer of title i n real estate and of corporate disputes under Russian law. These specific issues are dealt w i t h i n the light of the general approach of Russian courts to arbitration. Firstly, some necessary explanations are given in relation to Russian regulation, practice and attitude towards arbitration. Then, the approach of the Russian state commercial courts w i t h regard to the arbitrability of real estate and corporate disputes is described and compared w i t h their general attitude to arbitration manifested in Russian case law. Finally, the author's viewpoint on the possible concerns underlying the apparently incongruent stance of the commercial courts to the arbitrability of real estate and corporate disputes is discussed.
The book is devoted to non-residential buildings (premises) as objects of capital construction (real estate) and some types of urban development related to them. The purpose of the monograph is to analyze frequently encountered questions in practice at the intersection of private and public norms, sometimes without simple answers and solutions. All issues discussed in this monograph are at the intersection of several branches of law: civil law, urban planning law, land law, tax law . In relation to the subject of the study, the issues of cadastral registration and registration of property rights on real estate in the Unified State Register of Real Estate are examined. Some issues affect accounting.
Nowadays, most of the people are suffering from the attack of chronic diseases because of their lifestyle, food habits, and reduction in physical activities. Diabetes is one of the most common chronic diseases being suffered by the people of all ages. As a result, the healthcare sector is generating extensive data containing huge volume, enormous velocity, and a vast variety of heterogeneous sources. In such scenario, scientific solutions offer to harness these massive, heterogeneous and complex datasets to obtain more meaningful information. Moreover, machine learning algorithms can play a tremendous part in creating a statistical prediction-based model. The aim of this paper is to identify the prevalence of diabetes related to long-term complications among patients with type-2 diabetes mellitus. The processing and statistical analysis require machine learning environment known as Scikit-Learn, Pandas for Python, and R-Studio for R. In this work, machine learning approaches such as decision tree, random forest for developing classification system-based prediction model to assess type-2 diabetes mellitus chronic diseases have been studied. Additionally, we have proposed an algorithm which is solely based on random forest and tried to detect the complicated areas of type-2 diabetes patients.
The article is devoted to the analysis of results of application profitable and cost-based approaches to estimation of cost of the real estate objects which frequently appears much below their real market prices. Opportunities of the comparative approach use to an estimation of the real estate objects are considered, allowing to receive parameters of a real supply and demand in the market, and also in its frameworks of a mark method as alternatives of existing ways of an estimation.
Characteristics is given to the concepts “housing”, “residential premise”; legal category “residential premise” is considered from the point of view of embodiment of national (basic) standard housing, established by the State; system of viewpoint of European Court in Human Rights under the name “concept of housing” developing from authority to authority is being analyzed; the issue of diffusion of inter-subject concepts “housing” and “residential premise” in connection with the process of State integration into common legal and economic European space is being considered; the shortcomings of legal definition “residential premise” are being disclosed, as not reflecting its essence, purposefulness and variety of forms of its existence; in this respect the main conclusion on introduction of changes into art.15 and 16 of Housing Code has been made.
The paper examines the structure, governance, and balance sheets of state-controlled banks in Russia, which accounted for over 55 percent of the total assets in the country's banking system in early 2012. The author offers a credible estimate of the size of the country's state banking sector by including banks that are indirectly owned by public organizations. Contrary to some predictions based on the theoretical literature on economic transition, he explains the relatively high profitability and efficiency of Russian state-controlled banks by pointing to their competitive position in such functions as acquisition and disposal of assets on behalf of the government. Also suggested in the paper is a different way of looking at market concentration in Russia (by consolidating the market shares of core state-controlled banks), which produces a picture of a more concentrated market than officially reported. Lastly, one of the author's interesting conclusions is that China provides a better benchmark than the formerly centrally planned economies of Central and Eastern Europe by which to assess the viability of state ownership of banks in Russia and to evaluate the country's banking sector.
The paper examines the principles for the supervision of financial conglomerates proposed by BCBS in the consultative document published in December 2011. Moreover, the article proposes a number of suggestions worked out by the authors within the HSE research team.
