More machine learning – ScaledML

27 – 28 March 2019

The ScaledML conference is growing up; from a Saturday at Stanford to a two day event at the Computer History Museum with sponsors. http://scaledml.org/2019/

Two big new themes emerged

  • Concern for power efficiency (Simon Knowles, Graphcore, talked about Megawatts; Pete Warden, Tensorflow talked about milliwatts and energy harvesting
  • Development platforms – Adam D’Angelo, Quora, was particularly clear on how Quora operate development to efficiently support a small number of good developers

David Paterson gave the first talk on Domain Specific architectures for Neural Networks – an updated version of this talk https://cacm.acm.org/magazines/2018/9/230571-a-domain-specific-architecture-for-deep-neural-networks/fulltext

The roofline performance model is a useful way to visualize comparative performance. For future performance improvements functionally specific architectures are the way forward; this requires both hardware updates (what Google is doing with the TPUs) and improved compiler front and back ends.

Intel recognizes this trend – Wei Li described the work his team is doing to incorporate domain specific support into Xeon processors. This blog post has the gist of what he presented.

More on Micromobility

GoBike
requires rescue

Recently in Los Altos. Reminder that rental bikes require service and support – this one has a flat front tyre, damaged front handlebars, and a pair of spectacles poked into the cracked plastic. Emailing Ford GoBike to suggest they picked it up resulted in rather stilted customer service responses.

There’s lots of work still to do to get to the micromobility transformation in transport for suburbs. That transformation is a reasonable reaction to a poor infrastructure overburdened with vehicles much larger than they need to be for the movement of people and things they perform.

Mobility’s second great inflection point

Headline on a McKinsey article https://www.mckinsey.com/industries/automotive-and-assembly/our-insights/mobilitys-second-great-inflection-point

However, it entirely misses cycling, ebikes, and scooters. Perhaps the authors all live in snowy cold cities.

” .. the will to fix our cities is getting stronger. Urban populations, historically at the vanguard for change, are already more receptive to solutions such as ridesharing and carsharing, as well as EVs. ”

When the majority of trips are short, and as delivery robots gain adoption, the number of people willing and able to use a bicycle with electric power assist increases substantially. This has significant implications for the transportation business, and especially for automotive manufacturers.

Delivery of things

Another delivery robot company – this one operating at scale in Europe and making campus deliveries in the Valley. Starship raised $25m in June 2018. Runs on paths and sidewalks. No hints in the demo videos about how interacts with opposing direction bicycles and scooters.  Ideally something like this would be able to enter buildings and control lifts for campus deliveries. 

Commercial package delivery launch announcement (Oct 31 18) – in Milton Keynes now, and the SF Bay area before the end of the year. https://www.starship.xyz/press_releases/worlds-first-robot-package-delivery-launched-publicly-today/

Transportation futures talk – 21 Sept 18

LondonLINXswitches

London Internet Exchange, LINX, London 1

I’m due to do a talk at the Institute of Directors in Charlotte Square, Edinburgh on the afternoon of Friday 21st September 2018, as part of the Scottish International Week. Sign up here

It will be a review of the current excitement in the Valley around #micromobility, and an exploration of parallels between data packet transport and people and thing transport.

Urban transport – Bird and Lime

On Los Altos Avenue

Interesting to see the occasional Lime ebike in Los Altos – the nearest Lime bike location is posted as in Mountain View. No sighting yet of their Segway scooters.

For several years we tracked the increasing frequency of Teslas, and then an increasing variety of electric cars, on the streets in Los Altos. It seems like it’s almost time to do the same exercise, but for electrically assisted single person transport. Not all of them have two wheels, nor do they all have pedals. Segway sell a single wheel Ninebot. Lopfit walking bikes from Denmark have made it to Palo Alto.

These tie back into the Transportation as a System question – which company is best placed to gain scale by putting together solutions to the transportation requirements of people and things ? These personal scaled devices are part of the solution, and the travel pattern data they create have value, as indicated by the recent funding rounds. GV (was Google Ventures) led a $250m round for Lime in early June. Sequoia Capital led a $300m round for Bird (scooters) later the same month.

Updating, July 9th – the latest GV round also involves Uber, and has gone up to $335m.
