As others have said, F# interesting language features are computation expressions, active patterns, units and type-providers. The library, platforms and ecosystem benefits are gravy. Though subjective, the syntax is clean too, being somewhe

I did not downvote (and you're clear now) but your post is not a relevant argument. The determinism that the SFWT is arguing against is that of certain hidden variable theories of quantum mechanics. It states that if the humans are fre

Wow, your idea is heading incredibly towards the same general direction as https://en.wikipedia.org/wiki/Sparse_distributed_memory described there. Excellent!

One can view RNNs as a sort of generalization to markov chains. RNNs have the advantage of a memory, context tracking and are not limited to learning patterns of some specific length. RNNs can apply these advantages to learn subtleties of g

Ah, I was confused for a second—I'd thought Markov was a library, but you meant the markov assumption—the topics are actually loosely related and orthogonal. Your excellent looking library deals with reinforcement learning agents that

This is a medical case study however, not a journalistic piece and you two are being at least a little bit unfair, I think. Since seizures and sudoku are not a common combination, upon seeing the title, I assumed it was something conditiona

I agree that this wasn't done by the computer (did computers uncover the Higgs Boson?) but I also do not believe humans can take most of the credit: this was the result of a Man Machine System team up—trying to disentangle credit assig

All the things you mentioned (plus e.g. bayesian networks and Restricted Boltzmann Machines) are examples of Graphical Models. You can roughly think of (linear chain) CRFs as being to HMMs as logistic regression is to Naive Bayes. HMMs and

Time reversibility exists in quantum mechanics because observables are self adjoint operators. Closed systems evolve unitarily. In simpler terms, you can think of it as the requirement that maps preserve distances and are easily invertible.

In nature, decentralized networks are more the norm. You find them in neural, gene, protein and metabolic networks. You find them in mycorrhizal networks of forests and in various self-organizing systems. Food webs, IIRC are even more rando

The short version is, if this is correct (which is exceedingly unlikely) then either quantum mechanics is wrong or whether P=NP has just become irrelevant. This is because, as Scott Aaronson is often forced to tirelessly point out, an inabi

I must very strongly disagree with you. ScienceDaily is as good an aggregator as you'll find. Sometimes, I'll even purposely seek out their write-ups on a topic because of one thing they almost always do, while almost everyone els

SVMs were invented by a couple statisticians/mathematicians in the 60s. k-means also harkens back to the 60s, by mathematicians and control theorists. Decision Trees and Random forests were invented by a famous statistician, with the l

I might be mistaken, but it seems to me that the predictor should also be able to solve the halting problem. Additionally, if the entity to which the source-code is a descriptor for is so simple that they can be predicted without full simul

There are some doubting the veracity of the article, and while it is onesided in how it paints Newton, the main conclusion, how Newton's childhood might have contributed to his penchant for isolation is a solid one. Newton was in his t

Your code is not doing the same thing. A few minor bits; env has no 'lines' in its definition and String.sub does not allocate objects: it's better to think of String.sub, String.length, etc. as functions packaged in a module

As others have mentioned, when the assumptions of conditional independence are met, Gaussian NaiveBayes and MaxEnt will asymptotically learn the same classifier. Except NB will learn it in O(log dimensions) instead of O(dimensions) examples
