Consumer Electronics Show: Everything’s Connected, But What About Security and Privacy?

We spent last week at the Consumer Electronics Show (aka CES) in Las Vegas, with over 180,000 of our closest friends. And with 4,500 exhibitors present, you’d have less than 30 seconds at each booth if you wanted to talk to all of them. Many articles have covered the cool new things, so in this blogpost we are going to discuss our overall impressions as they relate to our work on consumer IoT security and privacy.

Not surprisingly, there were many interesting conference sessions and a wide variety of innovative products on display, including some that seemed to push the bounds of credibility in their claims. Integration of devices with voice-driven and other platforms was everywhere – Amazon Alexa, Google Assistant, Apple HomeKit, and Samsung SmartThings being the most widely adopted to date. 5G was a hot topic, especially for its improved speeds and flexibility, though specifics about its availability are still hard to pin down.

Everything these days is getting connected to the Internet – from cat toys to sports simulators to home automation. One area that seems to be gaining more traction because it has gone beyond the “gadget” stage and is solving real problems is health and Continue reading

Stuff The Internet Says On Scalability For January 18th, 2019

Sorry, Stuff The Internet Says On Scalability has been called on the account of wind, rain, power outages and general mayhem. We're all safe, but it's hard to write a post using stone knives and bear skins. See you next week.

Towards a hands-free query optimizer through deep learning

Towards a hands-free query optimizer through deep learning Marcus & Papaemmanouil, CIDR’19

Where the SageDB paper stopped— at the exploration of learned models to assist in query optimisation— today’s paper choice picks up, looking exclusively at the potential to apply learning (in this case deep reinforcement learning) to build a better optimiser.

Why reinforcement learning?

Query optimisers are traditionally composed of carefully tuned and complex heuristics based on years of experience. Feedback from the actual execution of query plans can be used to update cardinality estimates. Database cracking, adaptive indexing, and adaptive query processing all incorporate elements of feedback as well.

In this vision paper, we argue that recent advances in deep reinforcement learning (DRL) can be applied to query optimization, resulting in a “hands-free” optimizer that (1) can tune itself for a particular database automatically without requiring intervention from expert DBAs, and (2) tightly incorporates feedback from past query optimizations and executions in order to improve the performance of query execution plans generated in the future.

If we view query optimisation as a DRL problem, then in reinforcement learning terminology the optimiser is the agent, the current query plan is the state, and each available action Continue reading
