# Secret HPE AI chip, TensorFlow updates, neural networks writing themselves – and more

It's been an interesting fortnight, sorry, two weeks in AI. In addition to what we've already reported, we have news about HPE developing what looks like a neural network accelerator chip, TensorFlow updates, Google's effort to teach software to make software, and other bits and pieces. HPE’s ‘neural network processor’? The …

1. #### A matrix of meh-ristors

"“Probabilistic programming languages (PPLs) solve these problems by marrying probability with the representational power of programming languages. A probabilistic program is a mix of ordinary deterministic computation and randomly sampled values.”"

I'm fairly ignorant in this area (except for what I read on the El Reg, oy) but it strikes me that this approach notes the 'apparent randomness' of a real neural network, and kinda 'fakes' that randomness in a purely logical digital realm by shoehorning it in. It's interesting stuff, but I don't see how this approach can really replicate a NN's ability to adapt in a very complex way to inputs.

As I say tho, I'm not an expert here.

"Probabilistic Programming" has nothing to do withz Neural Networks and pattern recognition. Rather, it is about constructing models of some real-world system expressed as statememts, (e.g. "there is an earthquake" or "the burglar alarm is on"), conditional probabilities (e.g. "if there is an earthquake then the burglar alarm is on with p=0.9") or à priori probabilities (e.g. "probability of a burglary is 0.1", "probability of a false alarm is 0.05"). One then wants to ask things likes what is the probability of a burglary given that the burglar alarm is on and there was an earthquake?

See this introduction from a Manning book about a probabilistic programming language based on Scala: Probabilistic programming in a nutshell or this lecture at ETAP 2016: Structure and Interpretation of Probabilistic Programs.

Why Uber feels the need to invent Yet Another Probablistic Programming System is beyond me, but so it goes.

Then HP will add RSA signed certificates to lock the firmware ?

Just like it does with its notebook BIOS .. not allowing customers to even change a WiFi card...

Stay away from that crap. Don't ask for quotes, blacklist, hide.

3. #### Very nice

HP has long been working on memristor design, and use of memristors in an analog computer has been the goal. Good to see that it might just work.

4. #### Here weg, here we go, here...

I guess Google's next step ought to be getting their AI neural network designer to design a better AI neural network designer, wrap it in a recursive loop and go for a coffee.

Stick /that/ on your memristors, HPE.
