> DeepMind trained a neural network to more accurately predict future cooling requirements, in turn reducing the power usage of the cooling system by 40 percent.
But when you look at the DeepMind blog post (https://deepmind.com/blog/deepmind-ai-reduces-google-data-ce...), it looks like the 40% model is comparing to a baseline of doing nothing. So the question is : is this really something you require an AI research powerhouse like DeepMind for, or is it something a regular data science team could do?
that being said, even if ML gets you a 0.5% advantage over spreadsheet math, that is a non-trivial amount of savings on a national scale.
From what I've seen in several places though is companies tend not to listen to their own people, but are willing to make changes based on the advice of hired "experts". So the experts will come in and ask everyone what the challenges are and what they might do to improve. Then the "experts" will pick several low hanging fruit and find a few things that cross internal boundaries (the harder things to change) and make recommendations. Upper management will go with it and improvements will be made. I suppose the way to sum it up is that they bring objectivity to the table.
If one ML solution is better than the other one by only 0.01%, in this context it is worth a lot. It is a winner-take-all type of situation.
Edit: the second point was this: If one ML algorithm gives us a 1% saving and the other one gives us a 0.9% saving, you could say that is a 0.1% improvement or you could say that is a 10% (of 1% saving) solution. A percentage sign without context is not that meaningful.
So yes, many applications of ML are something "a regular data science team could do." However, isn't the main benefit of ML removing the need for a team of data scientists? Of course you will need some data scientists / ML engineers to support the ML product itself, but ultimately the gains will be realized from the ML doing the work that traditionally required a team of data scientists.
I agree it's not magic but it neither are 'manual' methods and at least the maths is a lot simpler.
You've missed my point. The thing is that building the ML model is NOT the hard part of machine learning in industry. The hard part is building an infrastructure that can make that machine learning model do something useful. It is much harder than people imagine. See for example this great paper by google for more details : https://static.googleusercontent.com/media/research.google.c...
"by applying DeepMind’s machine learning to our own Google data centres, we’ve managed to reduce the amount of energy we use for cooling by up to 40 percent. [...] Given how sophisticated Google’s data centres are already, it’s a phenomenal step forward."
I assume, because they haven't actually given an impressive number without massive wiggle room, that it's because they are clever enough to know the real number is embarrassingly low, but would welcome corrections.
I worked at one of the datacenters where they rolled this out. It definitely wasn't all that impressive in terms of real energy savings, it would temporarily make our PUE drop, but we'd have to make up for it after the recommendations were secured in order to account for the temporarily relaxed set points. It was mostly a PR thing from my point of view.
We can put people in a rocket and take them to the moon but we can't replace windows and make them look identical to the previous ones but with all of the modern efficiency. Because oh well, the building won't be looking exactly like two centuries ago or something.
Completely crazy, let me tell you... :(
And apparently the Green Deal was a failure - https://www.theguardian.com/environment/2016/apr/14/green-de....
There are about 2000 - 3000 grade 1 and grade 2* listed buildings in London. 92% of all listed buildings are grade 2; the other 8% are grade 1 or 2. So there's likely to be a fair amount of properties that are listed.

You even had to use authentic rubbish paint on the doors
Instead, I'm sure half the energy footprint goes to waste through those windows...
Plus, read my comments. I'm saying the government should take care and sponsor the fixes to ensure the quality while greatly reducing the energy bill (that's my thesis).
I'm not sure where you got the gripe against wood from. It lasts longer than uPVC given maintenance every 5 years, looks better, is more environmentally friendly and has similar thermal properties. Oh and it doesn't go yellow.
Hugely, I think it's a testament to the design that they still look great today. Double glazed wooden sash windows are however much pricier than a uPVC alternative which puts them out of reach of many.
Really, I couldn't care less if they replaced the frames with wood or whatever, as long as they made sure that they were thermally good and avoid wasting all of the heat...
Agreed, but wasn't this also an issue with steel windows in the 60s? uPVC put in in the early 90s already looks crap (IMO).
Especially when the tenant will take all the advantage of lower bills, increased comfort etc.
The only thing that comes to mind is that climate is supposed to be mild in the UK, so maybe double glazing makes less sense than in colder countries? But it can get pretty cold in the UK...
My comment wasn't meant as a criticism of your comment.
A contributing factor is the popularity of rented accommodation, including council-owned houses, where the pressure to invest in double-glazing is less (as tenants are responsible for gas/elec bills, but landlords are responsible for capital-expenditures and improvements) - so there's not much incentive to upgrade windows in that case.
But all new houses I've seen built since the late-80s all tend to have double-gazed windows, the majority have white PVC framing, but I see wooden ones occasionally too. I've never seen white PVC window framing turn yellow - my parents had their windows converted around 1994 - now 23 years later the frames are still pristine white - and I'm not aware of any special treatment or care they require.
That said, public perception of double-glazing salesmen isn't the best - they were the butt of many a joke in the 80s and 90s, including Blur's Parklife video: https://www.youtube.com/watch?v=YSuHrTfcikU - though I never understood myself, perhaps because they were a commonplace sighting?
That... and even today they seem to capitalize on their public perception with intentionally gauche TV ads: https://www.youtube.com/watch?v=OgqJPd_YJtE
A friend of mine lives in a single-glazed 13-storey 1960s apartment block. It can be quite drafty. There's no way it will ever be refitted and I'd give it a couple of decades until its demolition.
The UK's housing stock is very old on average and some of it is in very poor condition.
Any data to back this up? Personally I find it a pretty rare sight to see windows that aren't double glazed and if I came across a property without them it's absurd enough I wouldn't move into it.
Well, I've talked to people and been to quite a few places in the UK, Scotland, etc. I know many people living in London, the UK and Scotland. We all agree. I'm pretty sure it's the same all over the UK
And for the rental prices that you pay here, it's pretty shameful the state of the houses, windows included.
Page 3, Summary:
Around 83% of homes in each country have some double glazing. Northern Ireland has a higher percentage of homes which are fully double glazed, 62%, compared with 32-44% in the other countries.
So, ~60% of the houses are NOT fully double-glazed. In 2007. Srsly. And sure, it's from 2007... but I highly doubt the situation has changed...

Seriously thought, that's quite an unreadable interface.
With Machine Learning, natch: http://www.openenergi.com/virtual-power-station-with-big-dat...
come on folks, we can be better than this.
I also think the 10% figure is quite ambitious; especially given that they are at an early stage of negotiations.
Ie. trying to prefer supply near users to reduce losses in long transmission cables.
The whole thing seems rather tricky though, because the entire grid right now is run on a market based approach, where suppliers and users bid for the right to sell/use power every half hour. The ML in that case would have to be given to every company to make smarter bids.
I can see this transitioning quite easily from a 'we can sanitise this data ourselves' job to a 'screw it, let a massive neural net figure this out' one.
I think it's worth considering the overall characteristics of the "improved" algorithm, since the ML optimizations are likely analogous to leveraging based on an overfitted predictive model, and the objective of a power grid is resilience as well as efficiency.
Also, depending on how you define efficiency, it may be considered beneficial to shut down a coal plant and spin up a few hundred windmills, even if the resulting price per kilowatt hour increases by 5%.
Dispatch priority already ensures that if wind is available it will be used in preference to coal: https://www.economy-ni.gov.uk/consultations/priority-dispatc...
You're 100% correct about the "resilience" and "efficiency" part, and we currently have software for that as well (Google "Real-Time Contingency Analysis"), but the real improvements to be made in this area would be things that generally fall under the "smart grid" buzzword. The ability to automatically switch transmission lines in and out of service during an emergency event, better and/or automatic control frequency and voltage (which we do have currently, but could be further automated), and reaction/recovery/restoration after a relay incident (for example, an automatic "Blackstart" after a voltage collapse) would all fall under the kind of improvements needed to push electric grid technologies to the next level, in my opinion.
Demand is predictable so little to gain there.
How big is the market of providing excess demand? If I can turn on the AC or charge electric cars in the millions, what can I earn as a company?
The article does mention the losses involved in long distance transmission, but surely traditional approaches can already yield fairly well optimised planning for improving this sort of efficiency?
(Finally, this article seems quite light on details to me & doesn't mention a source Google press release or anything like that with more specifics. Maybe just better supply forecasting could yield bigger benefits that I imagine...)
There are so many opportunities to increase the efficiency of our electric networks. Forecasting demand is not something they do well, but more importantly they could improve Demand Response and Energy Efficiency programs. Oh, and most of the techniques they use to prevent and stop theft are a joke (that's a $6B/yr problem in the US).
The utilities have not been forced to innovate. They won't innovate on their own because there are no customers at risk - no competition. (Aside from smart meters and the main benefit from that was that they no longer had to pay for meter readers.)
There is a WORLD of opportunity for utilities to become more efficient, but they will not do it on their own. Our regulators need to force them to innovate.
Kudos to DM for this work, but I will be more impressed if they can actually get a major utility to implement these solutions.
- Source?
"The utilities have not been forced to innovate. They won't innovate on their own because there are no customers at risk - no competition."
- Also, what data can you provide to back this up? I work in the industry, and I can tell you that innovation will depend largely on the type of energy market that the utility operates in, whether or not they are a vertically integrated company, regulated or unregulated, IOU or POU, as well as a ton of other variables. So while maybe its true that not every single company is innovating, to generally say that they "won't innovate" or that there is "no competition" is simply wrong as well as spreading incorrect information about the industry.
I'd check out this is you're interested in learning more about the utility industry: https://www.osti.gov/scitech/biblio/15001013
A grid has all sorts of actors involved, a whole bunch of whom are there purely to make money (manage risk, gamble... tom-a-to/tom-ar-to) - bolting an AI onto a complex system and then letting people !#$!@# with it to get their hedge contracts into the money is practically a guaranteed scenario.
Because the Numenta algorithms are optimized for time-series data, their areas of strength are prediction and anomaly detection. When I worked there (5 years ago, they've made a lot of progress since then), one of their main "case studies" was energy usage in large buildings. Jeff Hawkins gave the keynote presentation at Strangeloop 2012 where he discussed this specific application of the algorithms, lowering energy bills in factories by predicting the next day's usage in advance. [6]
My understanding is that the algorithms worked particularly well for energy consumption data (e.g. energy drops at night on weekdays, drops on weekends, spikes in meeting room X at 10-11am every day, etc). I would not be surprised at all if DeepMind is able to capture savings using similar methods.

Feel free to underestimate them. It's really not my problem.
And do pompous, abrasive comments like yours really add anything to the discussion? Why don't you elaborate on why they are a "joke" to serious intellectuals like yourself.
