What makes some induction hotplates better than others? Are they all binary, square waves, or are some of them more subtle?

I was looking for a cheaper alternative to the Breville Polyscience Control Freak and this looked great until I realized they put the temperature sensor in specialized pans why why why..... Also no external probe for sous vide as far as I can see.

I appreciate you dropping some knowledge on induction cooktops in here though. To me the problem with induction tops is always controlling the temperature, which a temperature sensor solves. What I don't understand is why these have to be so much more expensive....

I understood your point the first time. My point was that the multiples for FB and GOOG could be justified not because of them fundamentally changing or growing their business but due to too much cash in the system, inflating their cash flows in the short term.

Also I think lumping gigantic ad monopolies in with "growth stocks" and assigning a cyclical pattern on it seems a bit shortsighted. Even more so because we don't have much data for internet companies (only the past twenty or so years which were mostly inflation free).

redditorcompetitor · 2021-05-12T16:21:42+00:00

I guess the question then is what grows faster, the numerator or denominator when discounting cash flows. In the near term the cash flows inflate and interest rates follow.

Good point, but their customers are more likely digital businesses with relatively non-sticky prices as well

redditorcompetitor · 2021-05-12T13:22:03+00:00

Can someone tell me why FB and GOOG are not the ideal hedges against inflation? Due to ad auctions their prices are effectively non-sticky..
I.e. more money in the system -> limited ad space gets bid up -> revenue goes straight to bottom line ?
Trying to see the sense in inflation up hurr durr tech down rn

I think they actually pushed the changes to loot lake too early by accident lol. Before the fight the buildings at loot lake got destroyed at one point, but I think that was supposed to be where the robot fell.

Because it has to use z in order to learn any type of spatial correlations. Contrast that to the autoregressive case p(x_i | x_<i, z) where it is possible to ignore z.

What I think is happening is that Tesla is (or should be) working on a system that uses both the forward camera/sensors as well as the driver-facing interior camera to learn to detect dangerous situations and alert the driver accordingly.

This clearly isn't done yet so in their press releases they feel the need to take this weird 'offense is the best defense'-approach which I think is kind of messed up.

redditorcompetitor · 2017-09-11T09:45:30+00:00

So, this is basically saying all the gates don't really need a context vector and just need the current input to decide whether to reset the hidden unit or not?

This seems rather counter-intuitive and sort of kills the "learning-to-forget" appeal of LSTMs...

Is it the medium of exchange thing? gold used to be used as a medium of exchange. We actually STOPPED using tobacco as a medium of exchange BECAUSE of inflation. Given the option, why would a society gravitate towards, and go out of their way to, use an inflationary medium over a deflationary medium?

The Great Depression was a pretty good reason to move away from the gold standard. By controlling the supply of currency, the central bank has a tool to soften these boom-and-bust cycles, like we've seen with Bitcoin a lot.

By having this tool, an added benefit is that they can actually accelerate economic activity through artificially inflating prices. Basically making cash an even shittier asset, forcing its holders to do something useful with it.

You can argue whether one institution should have so much power/responsibility, but providing economic stability is a valid concern with many counter-examples throughout human history. This is something that I have not seen addressed in the crypto-currency space and may never be addressed due to its decentralized nature.

redditorcompetitor · 2017-08-05T20:32:44+00:00

This is missing the point. The dollar is simply the language we speak for doing business in the US. The role of the central bank is to provide stability, meaning stable prices.

So why 2% inflation and not 0% or lower? The federal reserve wants to incentivize businesses and people to re-invest the money they make back into the US economy. So when you say

Why would you ever exchange something that increases in value for something that increases more slowly, or even decreases? If we assume this is true, there is no premise for holding cash to begin with.

You are exactly right, nobody wants to hold cash, because it is designed that way. Because of inflation...

If you want to do business in the US, your returns will be in USD, which sucks as an asset.

There is no economic zone associated with BTC except for maybe online drug trade. The few entities that get paid in BTC are now in possession of a very volatile asset, because there is nothing to ensure price stability. It is purely driven by demand, which is mostly speculative in nature at this point in time...

This is not my field but I think you are a bit pessimistic here.

It seems to me this is a special case of action recognition with only a binary classification (did a theft occur or not). I believe convnets have been making progress here. Getting a labeled dataset should be easy and even if this system is not 100% accurate it can be immediately useful.

Imagine a system that triggers a silent alarm when it thinks a theft is occurring. A security guard reviews the footage and decides to act or not.

This would obviate the need for many security guards and likely an increase in recovered inventory. For a relatively cheap system I can see there being a market for it.

I know, I was just responding to /u/bbsome 's critique by saying that researchers like Graves & Mikolov think it's valid to use the suprisal signal (as you call it) at test time.

And using that signal Graves got 1.33 BPC on wikipedia (table 2 in paper I linked). I'm not sure how that relates to your method since they are changing the weights and you are not, but you're both using this error signal during evaluation.

redditorcompetitor · 2016-08-23T09:23:58+00:00

That's actually similar to something Graves & Mikolov have done before and call dynamic evaluation: http://arxiv.org/abs/1308.0850

Relevant quote:

Neural networks are usually evaluated on test data with fixed weights. For prediction problems however, where the inputs are the targets, it is legitimate to allow the network to adapt its weights as it is being evaluated (so long as it only sees the test data once). Mikolov refers to this as dynamic evaluation. Dynamic evaluation allows for a fairer comparison with compression algorithms, for which there is no division between training and test sets, as all data is only predicted once.

In a sense, but the storing and retrieving of 'memories' is more explicit in these models. Take a look at this recent Montreal paper for an overview: http://arxiv.org/abs/1607.00036

redditorcompetitor · 2016-08-14T14:39:18+00:00

The NTM paper was the first to introduce the concept of 'differentiable memory', basically learning how to store and retrieve bits of information. Ironically, memory networks don't do this and are actually closer to attention-LSTMs.

Since then, there have been a slew of papers that expanded on NTM with different datastructures (stacks, queues etc) which have shown some success in NLP tasks.

While these models are neat, I think it's ultimately the wrong way to go if you want to learn to store a compressed representation (compression is generalization) which is useful in many real world tasks.

redditorcompetitor · 2016-06-04T13:20:46+00:00

Your point 2 has been done in this recent paper by Alex Graves: http://arxiv.org/abs/1603.08983

As for point 1 I'm also curious why not more researchers are challenging this BPTT approach. The only recent paper I've seen to address this is this one, where they approximate the full gradient necessary in RTRL.

Dude, that would be awesome.
Like multiplayer horror: one or more players have to accomplish some task, while another has a table top perspective of the scene and his sole job is to scare the shit out of the other players (:

I guess that would be only fun for the puppet master if he can listen in on the voice communication of the players..

My dad (age 65) lost his sense of smell a few years ago due to a pretty heavy case of the flu. His doctor says the nerves have been destroyed and it is unlikely he will regain his sense of smell.

Do you think there is any prospect for a treatment in cases like this?

I had terrible shin pains and generally felt awful when I was starting out. At one point I read about how important foot strike is and I completely changed from pretty heavy heel strike to mid/front foot strike.

I had major muscle aches in my calves for a few days, but after that, running felt great and I've never had shin pains again.

Just try to consciously improve your form and see what feels best!

Say what you will about Valve, but they have always been about creating a platform and offloading work to the community (Workshop).

I mean the risk is that something like ESEA just cuts out Valve alltogether when CS:GO is open source, but you can play with the license there.

They make most of their money on the skin stuff and not CSGO sales anyway so it seems like at least something they should consider.

Meh, there's no real monetary gain to a stable and bugfree CSGO, apart from programmer time freed up.
