Machine Learning Algorithm Can Tell If You Are Drunk Tweeting

So you’ve had a few drinks and decide it would be a great idea to drunk text someone? The next morning you wake up and check your phone to see several responses which make you swear to never drink again (or at least until the next night out with your friends). The next worst thing? Drunk Tweeting.

Drunk texting is to a certain person, but drunk tweeting will see your message shared around the entire world for all to see. As a response Nabil Hossain at the University of Rochester, New York, has made a machine learning program that can spot drunk tweets.

After collecting thousands of geotagged twitter posts from New York state, the team created a machine learning program that could answer three questions.

  1. Does the tweet make any reference to drinking alcoholic beverages?
  2. If so, is the tweet about the tweeter him/herself drinking alcoholic beverages?
  3. If so, is it likely that the tweet was sent at the time and place the tweeter was consuming alcoholic beverages?

By answering these three questions the machine learning program could tell if you are talking about the past or present drinking and if so what are the chances you were drunk at the time. By getting the program to learn from 80% of their collected tweets, the machine learning algorithm was able to correctly identify the remaining 20% of tweets as drunk tweets 82-92% of the time.

By then adding “home detection” to the equation, Hossain was able to calculate who preferred to drink at home or out in the city using the geotagging information. Sadly the system won’t be able to spot and stop you drink tweeting next time you have a glass or two but maybe it could in the future.

New Car Hopes To Stop Drink Driving

It’s the weekend and you’ve gone for a small drink with your friends. Suddenly one turns into two, and two into three. You go to start your car, put the key in the ignition and then suddenly from nowhere, “I’m sorry, I can’t do that”. No your not losing your mind or experiencing the start of a robotic revolution,  instead a new system that could be in your cars soon has detected your blood alcohol level and refuses to start for you. Taxi tonight it is.

DADSS (Driver Alcohol Detection System for Safety) is a new system that could potentially be installed in cars in the near future. At the moment, two prototypes are in testing, first up is the good old fashion breathalyser method, with a sensor in the steering wheel or driver side door. The alternative is a touch sensor on the gear shift or ignition button, that would ‘scan’ your blood alcohol level. If either of these pickups read higher than the legal limit and your car won’t start.

While not designed as a required feature for new cars, the makers, the national highway traffic safety agency (NHTSA) means parents could pay that little extra to ensure that no one makes a decision to just pop down the shops for a little extra drink after a few during a party. A demonstration of the system can be seen in the video below.

While it’s getting safer to drive, anyone who has been impacted by drunk driving can tell you that figures don’t matter. One mistake is all it takes, and with systems like DADSS being created to help curve away those single mistakes the roads can only get safer.
