I was not aware of symbolic regression at all, but I'm wondering now if it couldn't be replicated by some feature engineering or playing around with smth like the Box Cox transformation. You could afterwards use some feature selec

Sounds about right. The nice thing is that if you're mentally prepared for it you have a good change of pulling through.

My approach, which I don't claim to be necessarily the fastest, somewhat resembles what you first mentioned (going slowly, looking up every word etc.). I recommend the following: 1. Give yourself time and accept that there will be thin

I'm not really saying that 80k is a little - it's not. It's more than fair - just not a shitload. Note however that the chart shows disposable income, which I'm pretty sure is the one after tax. 80k gross is more like 48

Well, in the US the equivalent would be around 200k USD. You should also take into account the marginal tax rate of 52%, which yields a net income of a bit below 4k/month. I'm not really complaining, mind you. It's nice to li

Yeah, but that should only prevent duplicates due to technical errors, but not duplicates because the person actually made a number of distinct purchases my mistake. Take a look also at edwinwee's answer below.

Thanks for the reply :)

Just out of curiosity, does the idempotency guarantee cover deliberate shopper actions, or just retries due to network errors? Shouldn't high velocity + high amount purchases be treated as potential (friendly) fraud and blocked by some

by leto_ii 7y ago
At a brief glance it seems they ensure idempotency w.r.t. possible errors/network failures etc. not necessarily to multiple purchases done by the customer by mistake. In that case I think some high velocity fraud filters should kick in

This was a valuable read. I think a similar misunderstanding takes place with Hobbes's idea that the man in the state of nature lived in a war of all against all. There's simply no evidence that this ever happened, even though it

It's funny to think that there was a time when the only way to get massive amounts of data about the population was to go door-to-door and ask questions to people. On the other hand relying on indirect data or even surveys can have ser

I really think it does. I also appreciate your idea of porting dplyr to python, keep up the good work :) This table sums up some of it: operation | time apply score + 1 | 30s apply score.values + 1 | 3s transform scor

by leto_ii 7y ago
Well, that's kind of the point. What's the purpose of the syntactic sugar? Is it just that, or is there some hidden performance difference? This is not clear at first sight.
557.
by leto_ii 7y ago
Indeed, but I was more specifically referring to smth like data.table, which I found simpler to use than Pandas.

Well, there's nothing to say that private corporations can't behave in the same way. I'm just saying that once you list these pressures are almost guaranteed to appear. I also strongly suspect that they're less present,

I tend to not agree with this line of thinking. This may be the case when you subject a company to financial market pressures by listing it on the stock exchange, but I don't think it's a natural imperative. Many companies do just

Could this simply be a misunderstanding of what an internal monologue is? Is there any science behind this?

This is worse than leeches. It's more like arsenic.

Well, we already have good measures for economic power, e.g. gdp. How would this extra measure help?

Is there any level or consistency of anecdotal evidence that you would find acceptable?

I really don't see how this would be a good idea. First of all it suggests that wealth is the be-all and end-all of human progress. It also implies that wealth creation is equivalent wherever it happens - that somehow if a place is mor
