Images generated by the artificial neural networks of the Google Brain team. Android dreams: some of what an image-recognition system imagines by recirculating noise.
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:

I made it out of the office just in time to see hundreds of my coworkers lined up on the hill overlooking Shoreline Amphitheater, watching the Space Shuttle riding a 747 toward NASA. I didn't take any photos, but the ones here express what I saw.
Googles on a hill waiting to see the #spaceshuttle

And there it is... space shuttle Endeavour piggy backing on a 747 on it's way to NASA Ames.

Why Google is the new Apple.

Everyone seems confused about Google these days.

Disgruntled former Google executives, tech pundits, regulatory officials, the media and even the Google-using public are confused about Google's transformation since co-founder Larry Page took over as CEO a year ago.

Here's what's happening: Google is becoming more like Apple in three fundamental ways.

(And that’s a good thing.)

Please read my column!: http://www.datamation.com/feature/lets-face-it-google-is-the-new-apple-1.html

Congratulations to Professor Judea Pearl for winning the A.M. Turing Award. Dr. Pearl's innovative exploration of applied Bayesian methods has been foundational to contemporary approaches to data mining and machine learning. He has written seminal works on heuristic search, causality and non-monotonic reasoning in artificial intelligence. I studied under him in the mid-90s, and he was influential in setting my career on its course. In the years I have been in Google Search Quality and Ad Traffic Quality, the lessons learned under Judea Pearl have been useful countless numbers of times -- starting from my very first interview at Google when I was able to re-purpose the technique used for efficient belief propagation in Bayesian networks to solve an interview question. He has also been outstanding as a voice of reason and compassion through the years following the tragic death of his son, the journalist Daniel Pearl. Again, congratulations!

Golden eagle in a field at UCSC. My family and I go hiking most weekends, which is our training for a planned climb of Half Dome in the summer. Recently we spotted this eagle on the university campus near our home, an uncommon treat in our part of California.

A nice challenge to audacious thinking.

Midpoint in Neal's talk is this shout out, "I saw the best minds of my generation writing spam filters." Why thank you kind sir.
"If the rocket blows up we're all dead..."
