The article says the same: > For the shoppers who were being paid under the new algorithm, we found that 40 percent of workers were earning more than 10 percent less than they would have under the old algorithm. What’s more, looking at d

I think there was no such time , not least because numerical analysis today leans on computer science to an extreme degree. I also think the two had very different development trajectories with some overlap (like much of maths).

I'm not sure the bulk of programmers are implementing CS concepts, except perhaps in a tautological sense. I think the Haskell sphere gives one a sense of what developing applications would look like if programmers really were implemen

There was a time when Software Engineering was the application of a branch of Mathematics called Computer Science.

Easier than most people think ... to get started, but there are relatively few masters compared to the number of practitioners.

In many situations, it is difficult to attribute causality to age because it is correlated with so many other things. Age brings with it kids, side quests, sleepless nights, partners, and so on. There is also a creeping apathy towards the N

In SWI for example, clpfd and friends rely on attribute values and hook predicates to interject the backtracking process with their own thing. SWI provides those things so that it can be extended. Non trivial Prolog programs which only use

Run in backwards, so they say, but not really. Most things you'll write can't run backwards. You have to write them in a special way for that to be possible, and even then what it means is that you can do a depth first search to f

Prolog variables are immutable by default. Data structures are the same as the immutable functional programming counterparts (no arrays, and tree based everything). Recursion is the only way to loop. Map, filter, fold(l/r), reduce, acc

In my opinion, if you are after the mystical experience of understanding functional programming, you're better off learning Prolog. I think it has more to offer in terms of insight, because wrapping your head around the language only t

I'm not sure knowledge of technologies is ever more than a temporary distinguishing factor. I think engineers are distinguished more substantially by a depth of understand of the fundamentals. By definition, fundamentals do not change

We live in a time when there are many more alleged machine learning roles than real ones. I'd argue that if you are not spending >50% of your time in model development and research then it is not a machine learning role. I'd al

They had a neurotypical control group, their effect size is massive, and clearly separates the autistic group from the control group. They reject the null hypothesis that there is no difference between the groups, and argue from literature

I struggle to see why one may want to use an interactive analysis toolkit via C++. Could anyone who has used ROOT enlighten me on this? I understand why you may write it in C++, but why would you want to invoke it with C++ for this sort of

With a fixed architecture, and a fixed dataset, as mentioned. So, a specific kind of neural network, and a fixed dataset.

Is there some work on how small a model with some specific epsilon perplexity could theoretically be? Given a fixed architecture and a fixed dataset, I presume there is a minimal number of parameters required for optimal representation.

Well if you used to have attention and now you do not, for the same proposition, then the proposition is no longer as interesting as it used to be. This may be due to reasons specific to your proposition or it may apply to propositions gene

Yet you’re using OOP every time you call plot, predict, summary and so on: possibly without realising.

Those response rates are fairly awful with two groups that are markedly different. Seems very likely that they’d self-select on the face of it especially if they knew what the research question was.

Yeah totally agree. That the size of the tattoo or the number of them not increasing risk makes no sense. Somewhat like claiming whether you smoke a cigarette or 20 a day, the risk is the same. If the latter was true it would more likely in

Thank you. Your helpfulness and balanced evaluations are refreshing.

Does that imply that every possible branch is optimised separately and then convoluted thereafter? If so, does it scale for very branchy programs? Do you have any comparisons to a Gibbs based approach for any of the use case examples?

Noteworthy the difference an exact fitting makes over an approximation for a model like this. Fortran is amazing for this kind of exact work.

Not really. The world of Bayesian modelling has much fancier tools: Hamiltonian MC. See MC Stan. There’s also been Gibbs samplers and other techniques which support discrete decisions for donkeys years. You can write down just about anythin

I used to replace strict Boolean conditionals with sigmoids in order to achieve continuous transfer for Bayesian change-point models. Does this do something similar or is it fancier?

I’m sorry to read about so much pain experienced by so many. Do the people doing the traumatising typically know they are doing it? Do they typically deny it if confronted?

You should then be able to show that objective reality exists without recourse to subjective experience. I’m all ears :-)
