What Will be Left After the AI Bubble Pops?
Every bubble pops eventually. When this one goes, what will be left behind? Well, there will be little models – Hugging Face, Llama, etc – that run on commodity hardware. The people who are learning to “prompt engineer†these “toy models†have gotten far more out of them than even their makers imagined possible. They will continue to eke out new marginal gains from these little models, possibly enough to satisfy most of those low-stakes, low-dollar apÂ...Folksonomies: technology ai

Effects of Good Teachers on Student Outcomes
These findings would suggest that the difference in achievement gains between having a 25th percentile teacher (a not so effective teacher) and a 75th percentile teacher (an effective teacher) is over one-third of a standard deviation (0.35) in reading and almost half a standard deviation (0.48) in mathematics. Similarly, the difference in achievement gains between having a 50th percentile teacher (an average teacher) and a 90th percentile teacher (a very effective teacher) is about one-third...02 SEP 2016 by ideonexus
