  1. So ultimately, all the UBI does is raise the prices on everything for everyone.

    I can also weave a story. Now that potential landlords can make twice as much money on apartments, there is a boom in apartment construction. Prices go lower and everyone is happy.

    My naive economics seems just as valid as yours. Of course, you or I could make it more complex, but they would both still be crap. What one needs are empirical results which is why people are now doing experiments with UBI.

    However, some simple arguments can't be refuted. Guy has no money. UBI gives him money. Now he can buy stuff. Unless you are saying the price of everything goes up by the amount UBI gives (or more if you're a pessimist.)

  2. Thanks for replying with the citations. I hate to complain, since you did go to the effort to send the citations, which were interesting, but do you have any page numbers? You cite a 126 page report and a 336 page book which would take a long time to digest without more information. The short article you did post is interesting, but doesn't support your argument.

    You can search up to power plants very easily as Australia found out. Not only that but you can build a 1GW NG plant for less then $400m.

    My rough calculations show it would take about 10 billion to run the plant for 30 years at peak capacity. A rough cost estimate for a 1GW Tesla battery is about 1 billion which should (hopefully) cover most of the energy and waste used in construction. Of course, this is apple to oranges in many ways...

  3. Corporatism is destroying our biosphere, which will kill us. And it is predicated solely upon greed.

    As you know, it's an unfortunate consequence of capitalism and corporations inherit desire to exploit externalities. An ethical but more expensive way to extract energy will always lose in an unregulated market. I'm not sure, I would attribute it directly to greed. It's more a consequence of a system that allows guilt reducing deniability.

  4. But here's the thing, your idea of storage is built around batteries for the most part. It takes more energy and creates more waste to build them, then it does to build a natural gas power plant of comparable size and run it for 30 years.

    Citation needed.

    The parent NN sets "hyper-parameters", such as the number of layers, the size of each layer, the activation function, the convolution size, dropout rate, the learning rate damping factor, the batch size, etc. Then it turns the children NNs loose on the image dataset. It then sees which hyper-parameters lead to better/faster performance, and then applies ML techniques to learn better hyper-parameters.

    None of this is new. What is new, is that Google is now applying this recursively, and using AutoML to design a better AutoML. This is another step toward the singularity.

    Seems they are exposing/solving a dirty secret of deep learning. Yes, one can claim the network is learning features, but to get the best performance takes a human to design the structure to capture those features. However, I wonder if they are exploiting the massive amounts of data Google can access. One of the hard aspects of ML is the statistical bias given a limited amount of data relative to the set of relevant concepts. If they are coming up with ways of helping these networks with their own data, it's not surprising the AutoML technique works. Seems they are doing something sophisticated since they are using reinforcement learning, but their webpage is light on details. I'd like to see if they are beating humans given a equal set of training data. (Of course, that training data yields more biased results over time...)

To apply a mathematical model to get that number, we'd have to be able to verify the model to that accuracy, and we'd have to make sure all real-world possibilities are accounted for. If there's a one in a trillion chance that accidental contamination of a sample would make it return a false positive, the probability estimate is off by at least eight orders of magnitude.

  13. Each job should pay what it is worth. Do you think a burger flipper should make the same as a highly skilled computer programmer?

    Do you really think jobs pay what they are worth? Employers will pay the burgers flippers as little as they can, irrespective of how much they are worth. They also have little need to compete with each other on salary since the unskilled workers have been made interchangeable. Instead the tax payers are in essence subsidizing the owners to help pay their workers a living wage.

    Seriously, not all jobs are meant or worth paying a wage to live off of....some ARE only for extra money on the side, or starting jobs for teens.

    Then why are people trying to make a living off those jobs. I don't really care what was intended, I care about what is happening.

    This has been the norm for decades, and only recently for some reason, has everyone started thinking that ANYTHING you could possibly do for money should pay enough to be your sole source of income.

    I think you've got things backwards. Now, people have to struggle and do anything just to get enough money to live.

    If the individual doesn't like the jobs they are being offered, then THEY need to figure out what to do or what jobs to seek that do give enough compensation to live off of solely.....

    Some have suggested Damore's honesty and intentions should be questioned because of that. That's a reasonable thing to do.

    You see this on Slashdot all the time. How many people here disagree with the 97% or so of climate scientists on Climate Change, for example? It certainly is more than 3%. Are these people experts in climate change? Do they have all the figures available to them? Do they have insights that Michael Mann et al don't?

    I think the is an interesting issue. For the most part, neither side of the slashdot debate are experts. How do they determine which experts to listen to. Why should they even believe that 97% of the climate scientists believe in climate change? What experts give them this information? If they are not listening to experts, how do they form their opinion?

    The case for social science is even more complex. I think the most damning argument against Damore is not that he thinks he can beat the experts, it's that maybe there are no good experts in this area. I think this is the real danger; if all science is lumped together, questionable research can be used to weaken the strong work. Personally, I assume climate science fits in the strong camp, but I don't have the time to do extensive research myself, so I have to pick my experts.

    Well the issue has been sufficiently politicized that it's difficult to assess expert opinions without a lot of research. However, CRA did increase the number of mortgages which would increase the prices of houses. This created a tempting opportunity for real estate investment. Once the financial industry schemed how to hide bad mortgages, the flippers and scammers were off to the races. At that point, a positive feedback loop can cause a rapid rise in prices.

    Mortgage-backed securities have been around for many decades. They were quite popular in the 1970s. They were used in the events of 2006-2008, but they weren't new, so their existence wasn't the cause.

    Credit default swaps were invented by Blythe Masters from JP Morgan in 1994 and increased in use in the early 2000s. It's interesting that it took 12 years. I would guess that the financial players are always trying to cook up new schemes within the current rules. Perhaps they even considered this a safe technique. It was clearly fine for a while. However, there are often unintended consequences when trying new things. Also, it's well know that their models didn't take into account heavy tail distributions caused by correlations in variables.

    Also from the Subprime Mortgage Wikipedia page/,

    The Financial Crisis Inquiry Commission (majority report), Federal Reserve economists, and several academic researchers have stated that government affordable housing policies were not the major cause of the financial crisis.[6][112] They also state that Community Reinvestment Act loans outperformed other "subprime" mortgages, and GSE mortgages performed better than private label securitizations.

    Thanks for taking the time to give an in depth response. If I can successfully paraphrase that means I probably understand. Let me give it a try.

    The problem seems to be based on the discrete cycle of payment. Assume you make money every week and you pay money every week. To find your profit you sum up what you make with what you pay. Unfortunately, due to the discrete nature of this process, it bounces around a lot. You have might have a surplus of money at some point and then it drops down at the end of the week when you pay things like salaries. Given that you don't want to always be taking out loans, this graph must always be on the positive with a reasonable buffer. It's also exacerbated by other things that are based on a longer cycles. The problem is with taxes the government just looks at your "profit" at the end of the year. This will be extra bad for companies that have Christmas focused profits. For a modest size company this might generate a large amount of tax.

    So is this a problem in the long term? At the start of the next year you would have a big expense as you pay all your bills. Shouldn't this balance the profit at the end of the year. I guess if you are a successful business and things are growing at a reasonable rate then your profit will always be too high. I agree this doesn't seem fair. What you need is a way to smooth your money curve. I assume many companies go to considerable effort to minimize the impact at the end of the year.

    As for your inductive argument, there are many cases where it is not true. Many machine learning algorithms suffer from the curse of dimensionality. Too many parameters and the results are worthless. One needs to use things like L1 regularization which is related to compressed sensing to find sparse solutions (if they exist.)

    It's not that different. A lot of current machine learning can be viewed as tractable (often convex) and intractable optimization. Probably a big difference is the size of the problems; going from hundreds of parameters to millions/billions of parameters.

    Another interesting difference is many machine learning algorithms don't want to find the "optimal" solution. They either tweak the problem with regularization or do some type of early stopping. This is not just done for tractability, but also for the quality of the solution. It's still got a bit too much magic for my taste.
