Re: Best Strategy Toward Veganism

Thanks for the comments! There almost seems to be a link between how radical activism is and how much good people feel they have done Keeping in mind that I don't typically support environmentalism, I like this quote : A long–time environmental activist was speaking to an enthusiastic group of young...

Re: Antinatalist solution to WAS - curious to hear your thou

So I think that holds great promise, and that is why I am currently working on a small book on that, aiming to make that point among others. Awesome! Btw, Brian, have you seen this: http://www.onlyonesolutionsite.org/homepage.html ? Someone shared the link in 2012. It seems likely that such efforts...

Re: Antinatalist solution to WAS - curious to hear your thou

Thanks for this discussion. I think antinatalism for large herbivores would probably increase wild-animal suffering because the food those herbivores would have eaten would now feed many more, smaller, shorter-lived animals. I think antinatalism should operate at the level of primary production. Pla...

Fascinating! Thanks for the tips. Maybe a volunteer can help publish The Hedonistic Imperative, since most of the remaining work is "grunt work".

Re: The Expected Utility of Sex

You may have read " The Cost of Kids ". The most commonly used contraception is the male condom, and it has a perfect use 2% failure rate, and a typical use failure rate of 18%. This means that, if we assume the Many-Worlds Interpretation of Physics, that in 18% of universes where you had sex, even ...

Re: Which animals are fine to eat?

Hi Daniel :) Insects probably don't feel much pain, but even if they do, factory farming them would be ethically raising them. I don't agree . Slaughter on insect farms may not be humane and in some cases involves boiling alive (e.g., the Kreca company). There can also be problems prior to death . I...

We typically got spam every few days that Peter had to delete, so I figured this would save him time. I think we've only gotten one new substantial contributor in about a year (namely, Darklight).

Re: Lobby group for wild animal suffering?

Animal Charity Evaluators aims to do some of this kind of thinking as well, but ACE is still in its early days. I think research on advocacy is important, but the problem is it's a hard topic where there have been many debates throughout the history of the AR movement and other movements (abolition,...

Re: Earthquake Prediction Project

Each hidden node in this kind of network is roughly equivalent to a Perceptron on the input. The added output layer then basically functions as a bunch of Perceptrons on the hidden layer. Even with just one hidden node, this means that the input travels through a non-linear function (sigmoidal in t...

Re: Earthquake Prediction Project

Congrats. :) Training Error: 89.66% Validation Error: 81.92% Test Error: 77.88% Weird. The numbers should be the opposite. You're doing worst on the training set. So now I have a bit of a moral dilemma to consider. If this network can predict earthquakes something like 20% of the time, should I impl...

Very interesting! So I guess your neural network is doing quite well compared with linear regression.

Re: Earthquake Prediction Project

Though if you mean I should try just implementing a Perceptron without a hidden layer and doing Logistic Regression on the data, I suppose I could try that too. I was thinking just to do one output at a time, but I didn't realize you had ~64800 of them. :P You could try a subset of those outputs. I...

It's worth doing for your own edification up to diminishing returns. You may get to do similar projects for pay at a job, so keep that in mind when assessing the learning value.

Re: Earthquake Prediction Project

(also made this reply on FB) That's interesting about your earthquake data. The only explanation I have is the obvious one that it could be overfitting with more nodes or epochs, but if you have lots of data that shouldn't be true. Another obvious (and maybe not improbable) explanation is that there...

Re: How many hedons per dollar?

Unfortunately, I don't think they can be ignored. (Which is not to say veg advocacy is not effective.) I agree, but that illustrates why we can't just "ignore speculative stuff". There's no clear boundary between concrete and speculative, as the essay I linked earlier explains. Basically I have no ...

Re: How many hedons per dollar?

Infinite, because even if I were just avoiding a papercut, my infinitely many copies across the multiverse would all be doing the same. The expected hedons are also infinite because there's a nonzero probability of asymmetric insanely infinitely big payoffs. Less loftily, I think quantifying hedons ...
