Inspired to make a meaningful donation, I wondered: What is the best charitable cause in the world, and was it crazy to think that math and logic could help me find it?

All of these images were computer generated!

For the last few weeks, Googlers have been obsessed with an internal visualization tool that Alexander Mordvintsev in our Zurich office created to help us visually understand some of the things happening inside our deep neural networks for computer vision.  The tool essentially starts with an image, runs the model forwards and backwards, and then makes adjustments to the starting image in weird and magnificent ways.  

In the same way that when you are staring at clouds, and you can convince yourself that some part of the cloud looks like a head, maybe with some ears, and then your mind starts to reinforce that opinion, by seeing even more parts that fit that story ("wow, now I even see arms and a leg!"), the optimization process works in a similar manner, reinforcing what it thinks it is seeing.  Since the model is very deep, we can tap into it at various levels and get all kinds of remarkable effects.

Alexander, +Christopher Olah, and Mike Tyka wrote up a very nice blog post describing how this works:

There's also a bigger album of more of these pictures linked from the blog post:

I wasn't really arguing for "remove access to contraception". But I was thinking barrier methods work both ways.
But some things have changed since I had last checked numbers. As per http://www.cdc.gov/reproductivehealth/UnintendedPregnancy/PDF/Contraceptive_methods_508.pdf, it appears that IUCDs/implants are actually more effective than barrier methods today. I distinctly recall different relative efficacy data from a couple of decades back. Which is why I was scratching my head around the progress here.
Even accounting for that, though, a 40% change wouldn't result simply from switching types of contraception. But probably what worked was altering the time and authority of the decision. Women/girls making the choice a priori might be the real win.

But in my mind, the biggest issue remains the disconnect between the evolutionary urge for procreation, and the way modern society is structured. What was effective in the low tech hunter gatherer lifestyle may not necessarily function that well today. And we have to compensate for that with our frontal cortex. Except that teenage isn't so very conducive to that. Hmmpf!

Teenage pregnancies leading to monogamous stable relationships must be happening all right. I wonder what the numbers are though. Haven't tried to look up. Taking responsibility and teenage also don't seem to resonate well....

That mimicry is near-perfect. It even moves its tail just like a real spider.
