Can you elaborate on the "novel anomaly-detection algorithms" used here?

قبل 10 سنواتdiscuss

Full disclosure: I work at Numenta.

In the HTM model (presumably the Numenta algorithm you're referring to), synaptic weights are updated with every new data point in discrete time steps (as opposed to continuous). In that sense, HTM is an online learning model. There was an experimental implementation of Temporal Memory (one component in HTM) that batched up some of those operations into phases, but that still happened in a single time step and that implementation has since been phased out (pardon the pun).

For some additional literature on the topic, see: - "Why Neurons Have Thousands of Synapses, a Theory of Sequence Memory in Neocortex", http://journal.frontiersin.org/article/10.3389/fncir.2016.00... - "Continuous Online Sequence Learning with an Unsupervised Neural Network Model", http://www.mitpressjournals.org/doi/abs/10.1162/NECO_a_00893... - "The HTM Spatial Pooler: a neocortical algorithm for online sparse distributed coding", http://www.biorxiv.org/content/early/2016/11/02/085035.abstr...

There are more reasons to stay at a company than perceived value of options. Options are only part of overall compensation and, I don't know, maybe you can actually like your job.

See https://github.com/numenta/nab for anomaly detection results on real-world data, with comparisons to Twitter and Etsy Skyline.

I should also add when they mean "architecture" they mean it in the literal sense -- the physical structure in the brain in which encoding sentence meaning takes place.

Implications are that left mid-superior temporal cortex (LmSTC) carries information about sentence-level meaning, which had kind of already been implied in prior experimentation.

The discussion states that they "Provide preliminary evidence for a long-standing theoretical conjecture of cognitive science: that the brain, on some level, functions like a classical computer, representing structured semantic combinations by explicitly encoding the values of abstract variables", which is little more than hyperbole.

It's interesting, insofar as they identify a very specific region of the brain dedicated to a specific aspect of understanding language, and which plays a small role in a larger network of regions, but it's a bit of a stretch to imply that it's the "most important paper in cognitive neuroscience in many years". Pinker is quoted because this provides some empirical evidence for some of his theories.

In Mountain View, and likely elsewhere in the Bay Area, charitable organizations make the rounds once a month to basically do the same. They provide the bags, collect them, and presumably sell what they can for cash. As for batteries and other hazardous materials, there's a protocol to have the city pick them up for no charge. I've never had a problem getting rid of stuff and feeling like I'm doing it responsibly. It's hard to understand what value this adds beyond immediacy.

At least with the services I already take advantage of, it's all done in batches and my contribution is low compared to the overall haul. This is on-demand, so it's likely not as efficient.

I thought it was weird when I first heard it referred to as espresso, but the official name is "Aerobie® AeroPress® Coffee & Espresso Maker" and there doesn't seem to be any consensus on what _espresso_ actually is. The only common trait is that pressure is used to force water through ground coffee -- the Aeropress does qualify under that definition.

Actually seems like it'd be a decent use of what became of the ill-fated super collider project south of Dallas. A quarter of it has already been bored.

NuPIC, the Open Source project upon which Grok (Numenta's commercial product) is built has an active community at http://numenta.org/lists/. We had a workshop and hackathon a few weeks ago, more details can be found at http://numenta.com/learn/ and http://numenta.org/blog/2014/10/30/2014-fall-hackathon-outco..., respectively. See, also, https://github.com/numenta/nupic.research for the latest research efforts, https://github.com/numenta/NAB for forthcoming benchmarks, and of course http://numenta.org/ for overall details about NuPIC and http://numenta.com/ for Numenta, the company.

I've been there, having interviewed at both amazon and google and rejected at both. Ultimately, I'm better (and happier) for it. Eventualy found myself in the position of having to choose between multiple better offers. Use this as a learning opportunity -- other opportunities will come along, and this probably isn't the last you'll hear from either google or amazon.

Numenta is very much alive. Grok is available in the form of an AMI on the AWS EC2 marketplace, and if you're curious about how it all works under the hood, NuPIC, the core implementation is free software, available at https://github.com/numenta/nupic

FWIW, there is no learning on-chip. Machine learning is not the goal of this project, nor is its success dependent on it's learning capabilities (at least not at this phase). Where it does succeed, however, is in low-power computation in an architecture that is scalable and fault tolerant. LeCunn is criticizing an orange for not tasting like an apple.

In one of my previous roles as a software engineer at a local, independent office supply company, this would have been a compelling idea. They ran a small fleet of leased delivery trucks, and employed drivers hourly, so as a company there is an incentive to reduce delivery costs, and the benefits. At $29 per vehicle per month, it seems like optimized routes would pay for itself relatively quickly. You'd need only to shave a few hours and miles off the routes per month to cover the cost, and then anything else is pure cost saving.

However, I think there are some caveats. Drivers were given all items at the beginning of the day with a set of destinations and a deadline. As long as everything was delivered by the end of the day, everyone was happy. Sometimes there were exceptions, and multiple trips needed to be made, or certain customers needed to be given priority at the discretion of the sales rep. Obviously, the drivers aren't interested in optimized routes, as that would cut their pay, and other factors would override the initial route decisions.

Best case scenario, the company is at a point where they are having to turn away customers, and they are able to increase their revenue by adding capacity through optimized routes.

Assuming your workers can periodically report on progress, Socket.IO may fit the bill, has multiple implementations and provides graceful degradation for older browsers.

Wow. That contrast between New York and Bronx counties is staggering.

Good call. Looks like it's a british english convention. I'd not seen that before, thanks!

NuPIC was released as free software, in part, because there has been a strong interest in the academic research community. I encourage you to check out the mailing list (http://lists.numenta.org/mailman/listinfo/nupic_lists.nument...) for some recent examples.
