Check out our latest release in Gemini!

[Josh Woodward @joshwoodward]

Introducing Personal Intelligence. It's our answer to a top request: you can now personalize @GeminiApp by connecting your Google apps with a single tap. Launching as a beta in the U.S. for Pro/Ultra members, this marks our next step toward making Gemini more personal, proactive and powerful. Check it out!

@Calsef Moving to DeepMind. Organizational change 🙃

@WSDOT_East any update on SR 20 north cascades plowing? looking forward to biking it before it opens to cars!

Presenting world-scale inverse reinforcement learning (IRL) in Google Maps. Learn how RHIP, a new IRL algorithm, along with advances in graph compression & parallelization led to relative improvement in the quality of suggested routes in Google Maps. → https://t.co/5X9wwWwDS3

@markus_with_k 👋

@googlemaps Overall: 16-24% improvement in route accuracy

Personally, very excited by the potential this has for cycling and walking. These are often some of the most difficult routing problems, since its about so much more than just ETA

[Matt Barnes @BarnesMJ]

Our multi-year project using Inverse RL to improve route quality in @googlemaps is finally out!

Scaling was HARD. It took advancements on parallelization, graph compression, dominant eigenvector inspired initializers, and a new generalized IRL algorithm to make it possible.

[Markus Wulfmeier @m_wulfmeier]

Our 🌎-scale Inverse RL paper is finally out! Thrilled to share this multi-year project on route recommendation.

Understanding preferences is much harder than behaviour: not just WHAT but WHY!

We address the challenge via IRL on massive scale (100s Ms states, samples, params)!

@Calsef Scoop: sometimes I vote yes and other times I vote no!

[Matt Barnes @BarnesMJ]

@williamwilcock @CascadeBicycle @WAbikes How so? Cycling is inversely correlated with income (see Census stats below). And sales taxes are, in general, regressive.

@kkitani Yeah, GSA hosts an annual ice skating event for grad students. Watching them skate for the first time is magical (and inevitably comical).

@zacharylipton Hyperloop IS the shiny distraction.

[Matt Barnes @BarnesMJ]

@zacharylipton I think this trend partly stems from the techno-optimistic “CS can do anything” attitude, which has benefits (like you mention) but also downsides (esp. distracting from less-shiny, non-CS solutions). e.g. Hyperloop

@Calsef @ashleyrgold @eliglazier Ashley, I have a scoop for you.

It’s 231.
