López de Prado on machine learning in finance

Marcos López de Prado


Marcos López de Prado, whom we have featured in previous Math Scholar articles (see Article A, Article B and Article C), has been invited to present a keynote presentation at the ACM Conference on Artificial Intelligence in Finance, to be conducted virtually October 14-16, 2020.

López de Prado is a faculty member of Cornell University and also CEO of True Positive Technologies, LP, a private firm that provides machine learning techniques techniques for finance applications. He is also the author of two books in the field: Advances in Financial Machine Learning, published by Wiley

Day-trading in the age of coronavirus

Amateur pseudoscience

Suppose, during a TV weather broadcast, that the reporter presented “forecasts” from several private persons, wholly unqualified in meteorology, who base their forecasts on eyeballing a handful of charts and graphs. Most of us would never rely on such clearly amateurish methods ourselves, and would reject outright any such forecasts presented by others. If anyone took such forecasts seriously, when a severe storm was approaching, rather than relying on the consensus of qualified government scientists assisted by state-of-the-art supercomputer models, they would risk disaster, including the potential loss of life.

Similarly, suppose that after an examination at

Covid-19’s grim toll

The statistics are staggering: As of 1 June 2020, according to the Johns Hopkins University database, the U.S. had logged over 1.811 million confirmed cases of Covid-19 and over 105,000 deaths. The U.K. was next, with over 277,000 confirmed cases and over 38,000 deaths. Worldwide, over 6.3 million cases had been confirmed, with more than 376,000 deaths. If current trends continue, the U.S. death toll alone will soon exceed that of all wars in its history except for the Civil War and World War II.

The economic costs have been

Exit strategies for Covid-19

Marcos Lopez de Prado, the financial mathematician whom we have mentioned several times before in this venue (see, for example, Marcos Lopez de Prado testifies before U.S. Congress), has co-written an article entitled Exit Strategies for COVID-19: An Application of the K-SEIR Model. The article, actually a 52-page presentation file, is co-authored by Lopez de Prado (Cornell University) and Alexander Lipton (Hebrew University of Jerusalem and MIT).

In this presentation, the authors argue that universal lockdowns are blunt tools that should be employed only for brief periods of time. They then present a new mathematical model (K-SIER), which permits one

Is AI coming after your job?

Recent progress in artificial intelligence

It is no secret that artificial intelligence (AI) systems have made enormous strides in recent years, partly due to the adoption of Bayesian (probability-based) machine learning techniques rather than the rule-based techniques used until about 20 years ago. One highly publicized AI advance was the 2011 defeat of two champion contestants on the American quiz show “Jeopardy!” by an IBM-developed computer system named “Watson.” The Watson achievement was particularly impressive because it involved natural language understanding, i.e. the understanding of ordinary (and often tricky) English text. Legendary Jeopardy champ Ken Jennings conceded by writing on

Marcos Lopez de Prado testifies before U.S. Congress

Marcos Lopez de Prado

Famed quantitative financial mathematician Marcos Lopez de Prado, who was recently featured as Master of the Robots by Bloomberg, testified today (6 December 2019) before the U.S. Congress, together with four other panelists.

The topic for the panel, organized by the U.S. House Committee on Financial Services, was Robots on Wall Street: The Impact of AI on Capital Markets and Jobs in the Financial Services Industry. The five panelists who testified are:

Charlton McIlwain, Vice Provost for Faculty Engagement and Development and Professor of Media, Culture, and Communication at NYU. Marcos Lopez de Prado, Professor of

Jim Simons: The man who solved the market

Gregory Zuckerman, author of The Greatest Trade Ever, has published a new book highlighting the life and work of Jim Simons, who, at the age of 40, walked away from a very successful career as a research mathematician and cryptologist to try his hand at the financial markets, and ultimately revolutionized the field. Zuckerman’s new book is titled The Man Who Solved the Market: How Jim Simons Launched the Quant Revolution.

Upbringing and academic career

Simons’ background hardly suggested that he would one day lead one of the most successful, if not the most successful, quantitative hedge fund operation in

Feast or famine? The financial risks of climate change

The facts of climate change

At this point in time, the basic facts of climate change are not disputable in the least. Careful planet-wide observations by NASA and others have confirmed that 2018 was the fourth-warmest year in recorded history. The only warmer years were 2016, 2017 and 2015, respectively, and 18 of the 19 warmest years in history have occurred since 2001. Countless observational studies and supercomputer simulations have confirmed both the fact of warming and the conclusion that this warming is principally due to human activity. These studies and computations have been scrutinized in great

Quantum supremacy has been achieved; or has it?

Google’s quantum computing achievement

For at least three decades, teams of researchers have been exploring quantum computers for real-world applications in scientific research, engineering and finance. Researchers have dreamed of the day when quantum computers would first achieve “supremacy” over classical computers, in the sense that a quantum computer solving a particular problem faster than any present-day or soon-to-be-produced classical computer system.

In a Nature article dated 23 October 2019, researchers at Google announced that they have achieved exactly this.

Google researchers employed a custom-designed quantum processor, named “Sycamore,” consisting of programmable quantum

The “Master of the Robots” on machine learning in finance

Marcos Lopez de Prado

The Master of the Robots

Marcos Lopez de Prado, who was named Quant of the Year for 2019 by the Journal of Portfolio Management, is widely regarded as one of the leading quantitative mathematicians in today’s financial world. He currently ranks #1 among authors in the economics field on the SSRN research network, as measured by downloaded articles within the past 12 months.

In a Bloomberg article titled The Master of Robots Left AQR. Now He’s Coming for Wall Street, Lopez de Prado explains why he established his own company (True Positive Technologies) to dispense
