Global Surveillance Survey, AI’s Crisis of Reproducibility, Construction Drones, Bots Cheat at Hide-and-Seek

I read an interesting paper comparing the results of traditional passive learning (sitting in a lecture) versus active methods like the flipped classroom, where students watch videos at home and work on exercises in class. The paper is nicely summarized by this figure:

AI Knows Who Labeled the Data

The latest language models are great at answering questions about a given text passage. However, these models are also powerful enough to recognize an individual writer’s style, which can clue them in to the right answers. New research measures such annotator bias in several data sets.

The Long and Short of It

Not long ago, text-to-speech systems could read only a sentence at a time, and they were ranked according to their ability to accomplish that limited task. Now that they can orate entire books, we need new benchmarks.

Are Those Results Reproducible?

As deep learning becomes more resource-intensive, labs with better funding tend to achieve better results. One consequence is that less wealthy organizations often can’t replicate state-of-the-art successes. Some observers are calling it a crisis.
