Cornell Ann S. Bowers College of Computing and Information Science – “For years, the financial press has helped inform investors of all stripes. Cornell researchers have discovered it can also inform the algorithm behind a new financial predicting model. In their paper, “News-Based Sparse Machine Learning Models for Adaptive Asset Pricing,” published in Data Science in Science in April, the researchers draw from interdisciplinary fields such as machine learning, natural language processing (NLP) and finance to build a new, interpretable machine-learning framework that captures stock- and industry-specific information and predicts financial returns with greater accuracy than traditional models. “One of the knocks on machine learning is it’s not interpretable,” said Martin Wells, the Charles A. Alexander Professor of Statistical Sciences in the Cornell Ann. S Bowers College of Computing and Information Science and the paper’s senior author. “Often when researchers use big models such as these, they may not know what the outputs mean or what is underlying the model. This research leverages text data from the news to build interpretable machine-learning models where you can see the important features explicitly.”

Crawlers, search engines and the sleaze of generative AI companies
Search Engine Land: “…LLMs are not search engines It should now be very clear that an LLM is a different beast from a search engine. A language model’s response does not directly point back to the website(s) whose content was used to train the model. There is no economic exchange like we see with search… Continue Reading
Who Employs Your Doctor? Increasingly, a Private Equity Firm.
The New York Times: “A new study finds that private equity firms own more than half of all specialists in certain U.S. markets. In recent years, private equity firms have been gobbling up physician practices to form powerful medical groups across the country, according to a new report released Monday. In more than a quarter… Continue Reading
Corporate Climate Responsibility Monitor 2023
“The Corporate Climate Responsibility Monitor evaluates the transparency and integrity of companies’ climate pledges. Companies around the world are increasingly alert to the climate emergency. They face calls from a growing range of stakeholders to take responsibility for the impact of their activities. Most large companies now have public climate strategies and targets, many of… Continue Reading
Biggest Fossil Fuel Firms Responsible for a Third of Western Forests Burned
Yale Environment 360: “Emissions from the world’s 88 largest fossil fuel firms and cement makers are responsible for 37 percent of the forest burned in the western U.S. and Canada since 1986, according to a new study. “Over the last several decades, human-caused climate change has turned routine Western wildfires into exceptionally destructive events,” Kristina… Continue Reading
Tortoise Estate Planning—One Chore of Having a Pet That Lives 100 Years
WSJ [free link]: “…Desert tortoises can live more than 80 years. An African spurred tortoise, like Snoop Dogg, can reach 150. Jonathan, a Seychelle giant tortoise, is estimated to be at least 190 years old, according to officials of St Helena, an island in the South Atlantic where he lives. There is a photo taken… Continue Reading
How fast are the seas rising?
Yale Climate Connections: “The modern era of human-caused climate change — the Anthropocene — has also been called the Pyrocene because we’ve entered an age of fire, characterized by large wildfires of increasing size, intensity, and duration. But we propose another term for the modern era: the Aquacene, a time of rapidly increasing flooding from… Continue Reading
