Course Objective The objective of the course is to provide an introduction to using Eigen::Tensor as a high-level library for using Tensors in C++ projects. We learn the concept and techniques of the Eigen Tensor class How to declare, initialize Tensors of various ranks and types and how to access Tensor elements Elementary unary and binary operations involving Tensors More complex operations (reductions, contractions) Modifying the shape of Tensors The course is now live at the Academy, the github repository hosts C++ scripts used in the course.
The Climate Dictionary is an initiative of the United Nations Development Programme (UNDP) aimed at providing people worldwide with a simplified guide to understand climate change. The Dictionary (first published Aug 2023) seeks to bridge the gap between complex scientific jargon such as present in the IPCC publications and other scientific bodies and the public. Image: NASA Temperature Anomaly The Dictionary selects several dozen important climate concepts that are currently actively discussed worldwide with the aim to make them more accessible and relatable to individuals from various backgrounds and levels of expertise.
What are Input-Output Models? Environmentally Extended Multi-Regional Input-Output (EE-MRIO) tables describe economic relationships of economic actors (e.g. industrial sectors) operating within and between regions and their environmental repercussions. An EE MRIO augments the more basic and historically first proposed Input-Output Models (IO) with additional datasets and/or modeling assumptions in order to provide insights into the environmental foorprint of economic activity. Presently, the emphasis on negative externalities of economic activity (e.g., climate change, biodiversity loss) turns EE MRIO models into a useful conceptual and analytic tool.
Graphs seem to be everywhere in modern data science Graphs (and the related concept of Networks) have emerged from a relative mathematical and physics niche to an ubiquitous model for describing and interpreting various phenomena. While the scholarly account of how this came about would probably need a dedicated book, there is no doubt that one of the key factors that increased the visibility of the graph concept is the near universal adoption of digital social networks.

An overview of EU Financial Regulation initiatives In the European Union there are several ongoing large scale legislative and regulatory projects that transform the context within which individual, firms and the public sector interact economically. While financial and regulatory reform is an ongoing process in all jurisdictions globally, the size and supra-national nature of the European Union makes those projects particularly interesting. A new entry at the Open Risk Manual aims to provide a brief overview of ongoing projects / initiatives.

Business Model Risk - The Forgotten Risk Type Sustainable business models that demonstrate adequate profitability over long horizons are key to a healthy market economy. This applies to firms and organizations of any size and in any sector. But how do we determine what is sustainable and how can we tell a risky business structure from a stable one? On the small-scale end of the size spectrum we have the domain of startups and SME’s.
Risk Management Skills for the Fintech Era Financial services jobs continue being decimated. A recent (as of the initial post date) FT article was a sobering summary of the continuing transformation of the financial sector: 2015 alone has seen more than 10% reduction of the total workforce across large EU/US banks: As main drivers for this true jobs hecatomb are cited higher minimum capital requirements (that depress Return on Equity and hence require lower costs to restore it to investor acceptable levels), low interest rates that erode Profitability Margins, and a generally subdued economic landscape which reduces Volumes.
Open Source Risk Data with MongoDB and Python Open source software is all the rage those days in IT and the concept is making rapid inroads in all parts of the enterprise. An earlier comprehensive survey by Gartner, Inc. found that by 2011 more than half of organizations surveyed had adopted open-source software (OSS) solutions as part of their IT strategy. This percentage may have currently exceeded the 75% mark according to open source advisory firms.
The periodic table of risk elements You know the periodic table of elements, even if you flunked your science courses! It is the large colorful and blocky table that hanged on every school’s classrooms before becoming yet another mobile app. The periodic table is one of the early and iconic achievements of science. It lists all the pure chemical elements found in nature, the building blocks of all possible material substances.
Concentrating on Concentration Risk Senior economists such as Ben Bernanke were still studying the Great 30s Depression when the financial crisis struck in full force circa 2007. Given the complexity of the modern economic and financial landscape compared to the blessed good old days - we have no reports of FWMD (financial weapons of mass destruction) from back then - we can reasonably project that economists will be studying and pontificating on causes and remedies for the current crisis for the next 100 years or so
A mini course on risk management, its perils and the silver lining When talking about risk management, it is not very clear what we are talking about in broad terms, definitely not getting clearer when we start getting into the details and it is even not clear how to best use the (possibly flawed) insights we produce. Yet that’s what we have at this stage and with lemons we do lemonade.
