I'm really impressed at the level of attention paid to the data at each stage, to ensure that junk values weren't being propagated in the analysis. I wish ML papers aspired to this level of quality!

Special relativity is the set of equations that arises when you take a hypothesis: "you always perceive light as traveling at a speed `c`, no matter how fast you're going" and work out what would have to change in order to al

A tesla's battery pack is about 1000 pounds. The gasoline that would get a car to travel the same distance weighs about 100 pounds. For long haul, the fuel/battery weight would dominate engine weight, so unfortunately, I don'

Apologies - I didn't catch that the HF / healthy patients are from two different datasets. Agreed that this essentially invalidates the result. The missing experiment is to have a third dataset from yet another machine, with both

So first clarification is that heart failure != heart attack. Heart failure is a chronic condition where the heart is unable to pump hard enough to keep blood flowing through the body. Typically results in blood pooling in the leg, shortnes

Methane breaks down quickly, yes, but it also has a much, much more potent greenhouse effect. Taking both factors into account, releasing 1 ton of methane is estimated to be about equivalent to releasing 25 tons of CO2.

This article conflates many different definitions of elite: top quintile (20%) is mentioned at one point; super-elite colleges (<1%) is mentioned at another point; and superstar performers are probably <0.1%. I'm not sure it&#x27

The detail that this article misses is that the unuxpected piece has about 1 second of orchestral warning before the pianist comes in with a dramatic entrance. So Tianxu had about that long to figure out what to do, in contrast to Maria Joa

Pickle is only guaranteed to work within python versions and shouldn't be used as a long-term data storage strategy. It's really intended for quick-n-dirty serialization, or for multiprocessing communication, where the objects are

So if the utility is on the line for wildfire costs regardless, then here's a thought: maybe they'll do the economically rational thing and "accidentally" trigger smaller fires every so often.

"The training process behaves as a kind of one-way function. It is not possible to run a trained model backwards to reconstruct the input data; nor is it possible to “untrain” a model so that it will forget a specific part of its input

Not sure what CO2 levels that would generate - you'd need to measure to be sure. But my calculations suggest that effects are negligible even up to ~5000 ppm, and many of these studies are boohooing about 1-2000ppm conditions. I do thi

A few questions from a chemistry major 1. why extract from the air when you can just put a device on the smokestack of an existing coal or natural gas plant? The higher CO2 density of the effluent will make things more efficient. 2. Your ke

My take on the classical parts of it, as a classical pianist. Overall: stylistic coherency on the scale of ~15 seconds. Better than anything I've heard so far. Seems to have an attachment to pedal notes. Mozart: I would say Mozart&#x27

This title is really confused - backpropagation is one implementation of automatic differentiation, and yields a gradient. What you do with that gradient next is up to you - you can just follow it (steepest descent), or try other fancier se

Amazon absolutely has to deal with the fake review problem. In some ways, you can think of it as analogous to google search. Google's moneymaker isn't the search; it's the ads. But Google spends a lot of time fixing search qu

There's an aphorism: "objects are a poor man's closure; closures are a poor man's object". When I got to the point in SICP where I understood that, the word "magic" was very definitely justified :)
