Now you can generate your own dreamy neural net image

#deepdream  

For those of you who liked the post I shared a couple of weeks ago about the images generated by neural nets (old post: https://plus.google.com/+JeffDean/posts/jVBUgDxhbRd), I'm happy to announce that Alexander Mordvintsev, +Christopher Olah , and Mike Tyka have put together an open-source iPython notebook containing the code that generates these images, and you can play around with it on your own images.  (Note: this notebook depends on a few other packages, so you have to have enough persistence to install numpy and caffe to get this to work).  The iPython notebook is at https://github.com/google/deepdream, but see the blog post linked to by this post for details.

The blog post asks that people tag images they generate and share with #deepdream , so I suspect you can keep looking at that tag to see all kinds of weird and wonderful images.

Have fun, everyone!

+Christian Howard, sure I can ACTIVELY search for #deepdream , but I'd like it to PASSIVELY show up in my stream (just like everything else I Follow - people, communities, etc.)  I think being able to Follow a hashtag would be a good feature, BTW, in case any Googlers are listening...  :)

Wow. When I was in grad school at UW, the computer science department had one old, falling apart building. A few years after I graduated, they moved into a very nice shiny new building. Hard to believe, but they've now outgrown that and are going to add a second building.

All of these images were computer generated!

For the last few weeks, Googlers have been obsessed with an internal visualization tool that Alexander Mordvintsev in our Zurich office created to help us visually understand some of the things happening inside our deep neural networks for computer vision.  The tool essentially starts with an image, runs the model forwards and backwards, and then makes adjustments to the starting image in weird and magnificent ways.  

In the same way that when you are staring at clouds, and you can convince yourself that some part of the cloud looks like a head, maybe with some ears, and then your mind starts to reinforce that opinion, by seeing even more parts that fit that story ("wow, now I even see arms and a leg!"), the optimization process works in a similar manner, reinforcing what it thinks it is seeing.  Since the model is very deep, we can tap into it at various levels and get all kinds of remarkable effects.

Alexander, +Christopher Olah, and Mike Tyka wrote up a very nice blog post describing how this works:

There's also a bigger album of more of these pictures linked from the blog post:

Very nice report about the current state of biking infrastructure in northern Santa Clara County (Palo Alto, Mountain View, Sunnyvale, Los Altos), along with a vision for how the area could be so much better for bicyclists of all abilities and comfort levels. I especially like the North County as Copenhagen vision laid out starting on p. 24 of this PDF:

http://bikesiliconvalley.org/files/Google-Bike-Vision-Plan_high_res.pdf

I'm very happy Google commissioned this study, and I hope the city governments actually implement this.

Is instructive to study history of trails. Minuteman Bikeway near CAM, abutters opposed before, now (decades later) is seen as a huge asset. Next town over we are 20 years behind, a few dozen abutters (in a town of 25,000) stall any progress (and a multiuse path is progress over the status quo).

Was in MTV last week, the Permanente Creek path needs improvement. Those SLOW gates are wrong; treat cyclists like adults, thank you very much, and do not threaten scofflaws with physical harm (car analogy: imagine "traffic calming" implemented with jersey barriers forcing you to swerve through a single-lane opening in the road). They block tandems, they block trailers, they impede bidirectional movement at safe speeds. The Charleston crossing needs to be fixed -- it is no less safe to hop curbs and medians than it is to ride down to an intersection (more cars from more directions), u-turn, and then right. There also needs to be signs indicating all the names of all the cross streets and where they might take you to -- uncertain cyclists don't like getting lost and going a mile out of their way by accident. Down near the entrance to Shoreline Park, there's a diversion around a maintenance area, it is too narrow and there is a blind curve, two of us from opposite directions gave each other a start ( https://youtu.be/NxZJNFpjRM0 ). That needs to be fixed. This stuff is all cheap, ought to be noncontroversial, and it would help.

By-the-way, around CAM, some of the more heavily traveled streets appear to have a summer rush-hour bike fraction of 25%. Anyone who thinks bikes are toys or bikes are for yuppies ought to think what it would mean to add 25% to Cambridge/Somerville rush hour traffic, or to add 100 cars to the parking garage here.

Google has a pretty good computer vision research presence at this week's CVPR conference (see blog post). Many of the papers are presenting results of deep neural nets trained with the large scale distributed neural net training system that I and many others have been working on.

I won't be there, but if you'll be there, feel free to seek out these Google authors and ask them about their work.

Nobody eats dried pears anymore. We sure do consume a whole lot more high-fructose corn syrup (and surprisingly, lima beans), though.

H/t to +Greg Linden
 
Great data here. Very interesting how canned fruits and vegetables have faded from the US diet as it became much easier and cheaper to get fresh berries, fruit, vegetables, and tropical fruits any time of year.
We eat so many more vegetables than we used to. Also way more high-fructose corn syrup.

Introduction
I build large-scale computer systems.  I joined Google in 1999 and am currently a Google Fellow working in the Systems Infrastructure Group. While at Google, I have designed and implemented large portions of the company's advertising, crawling, indexing and query serving systems, along with various pieces of the distributed computing infrastructure that sits underneath most of Google's products. At various times, I've also worked on improving search quality, statistical machine translation, and various internal software development tools, and I've had significant involvement in the engineering hiring process.

Prior to joining Google, I was at DEC/Compaq's Western Research Laboratory, where I worked on profiling tools, microprocessor architecture, and information retrieval. Prior to graduate school, I worked at the World Health Organization's Global Programme on AIDS, developing software for statistical modeling and forecasting of the HIV/AIDS pandemic.

I earned a B.S. in computer science and economics (summa cum laude) from the University of Minnesota and received a Ph.D. and a M.S. in computer science from the University of Washington. I was elected to the National Academy of Engineering in 2009, which recognized my work on "the science and engineering of large-scale distributed computer systems."
