Python data mining and machine learning in action

Jack Pun presents best practices in pedagogy and teaching to facilitate effective content-subject learning at the secondary school level.Increasingly, parents are sending their children to English-medium instruction (EMI) secondary schools in their home countries, to prepare them for full immersion in EMI in English native-speaking countries. The book explores the teaching and learning processes in EMI senior secondary science classrooms based in thirty secondary schools in Hong Kong. Conducting analyses of classroom, teacher and student perception data, the author discusses the issues of teaching science through the medium of English in secondary schools, the implications and applications for professional development of science teachers and other content-subject teachers, and suggests strategies for teaching science in different EMI contexts.This volume is highly relevant to scholars in the field of educational linguistics, particularly in English language teaching, content-based inst

這是一本介紹如何應用大數據和機器學習技術來解決投資問題並提高投資績效的專著。近年來，機器學習和數據科學在投資中發揮著越來越大的作用。從本質上講，機器學習模型在挖掘數據背後的非線性關係上要強于傳統模型。借助機器學習和大數據，投資經理能夠做出以往傳統模型無法實現的預測，進而做出明智的決策。然而，在投資中，並不是所有的數據集和機器學習技術都對金融應用有用，也不是所有的機器學習技術都可以“即插即用”。《大數據、機器學習與量化投資》這本書由資深量化分析專家托尼‧吉達主編，彙集了多位業內頗具影響力的專家學者的前沿分享，闡釋如何應用大數據和機器學習技術來解決投資問題並提高投資績效。這本書共有13章，理論嚴謹，案例豐富，內容涵蓋機器學習在投資管理中的應用現狀和前景、另類數據和大數據在宏觀交易中的應用、處理大數據集的難點和解決方案、挖掘社交媒體數據集分析企業文化、使用自然語言處理技術進行投資者情緒分析、基於支持向量回歸的全球戰術性資產配置策略、強化學習和深度學習在投資組合優化中的應用等主題，可以作為量化投資從業者、金融算法研究人員、高等院校計算機專業和金融工程專業的師生以及機器學習愛好者的參考用書。

Proportionality in Action presents an empirical and comparative exploration of the proportionality doctrine, based on detailed accounts of the application of the framework by apex courts in six jurisdictions: Germany, Canada, South Africa, Israel, Poland and India. The analysis of each country is written and contextualized by a constitutional scholar from the relevant jurisdiction. Each country analysis draws upon a large sample of case law and employs a mixed methodological approach: an expansive coding scheme allows for quantitative analysis providing comparable and quantifiable measurements, which is enriched by qualitative analysis that engages with the substance of the decisions and captures nuance, contextualizing the data and providing it with meaning. The book concludes with a comparative chapter that synthesizes some of the most interesting findings. Focusing on deviations of the practice of proportionality from theory, the authors conclude their argument in support of an inte

What happens to risk as the economic horizon goes to zero and risk is seen as an exposure to a change in state that may occur instantaneously at any time? All activities that have been undertaken statically at a fixed finite horizon can now be reconsidered dynamically at a zero time horizon, with arrival rates at the core of the modeling. This book, aimed at practitioners and researchers in financial risk, delivers the theoretical framework and various applications of the newly established dynamic conic finance theory. The result is a nonlinear non-Gaussian valuation framework for risk management in finance. Risk-free assets disappear and low risk portfolios must pay for their risk reduction with negative expected returns. Hedges may be constructed to enhance value by exploiting risk interactions. Dynamic trading mechanisms are synthesized by machine learning algorithms. Optimal exposures are designed for option positioning simultaneously across all strikes and maturities.
