No more f-word while driving

How often a poor road surface drives you to madness? It would be great to visit car mechanic only on the occasion of a routine control. Wouldn’t it?

Inventors of the US company called RoadBotics found an answer to this problem. They offer a smartphone-enabled road inspection tool that creates the map of the condition of the road surface. The solution based on deep learning algorithms examines data from a video made by smartphone located behind the windshield of the vehicle. It recognizes problems such as cracks and potholes. In this way, the tool analyzes a 10-foot road section and assigns its level of damage. The results are presented on a five-point scale where 1 – green is an excellent surface condition and 5 – red is failed.

“This assessment does not suggest what needs to be done, but serves as a triage tool, allowing your engineers and public works staff to narrow down on what requires immediate attention. It complements your current process and enables your municipality to reduce time spent on inspecting roads and focus on maintenance.”[1]

Savannah is the city that has already employed this solution. RoadBotics has analyzed half of the streets and roadways in the city within a few months at the costs of nearly 25 000 $. Normally, the city would have to hire interns who would take 3 years to perform an analysis of the road conditions in the entire city.

Heath Lloyd, the City’s Chief Infrastructure and Development Officer said:

“This partnership with RoadBotics will allow us to better assess the overall condition of City roadways and increase the accuracy of the data collected. It ultimately allows us to be more effective in managing the replacement of our infrastructure”[2]

RoadBotics was introduced to URBAN-X, the leading accelerator for startups. It is constantly working on developing its product, among others using it in self-driving cars.

Facebook’s new algorithm is about to put end to clickbait

 

ClickbaitEvery time You open Facebook News Feed you’re likely to see many clickbait articles with headlines like: “I thought I wanted a baby someday, but after watching this … yikes.”;” You’ll NEVER believe which two stars got into a fight on the red carpet last night!! CLICK to find out which starlet was fighting over!! à”. Those headlines are annoying and articles they direct to almost never meet our expectations from the time we clicked on them in a Facebook feed.

The great thing is that Facebook took notice of it and for the second time tried to fight with them. Previously the algorithm was searching for distribution of posts that led people to click on them and afterwards very quickly come back to News Feed without liking the page. This didn’t help much as these type of posts were still showing quite regularly.  It was easy to overcome the algorithm by creating a new page or even new post which had some time until it was stopped.

The new algorithm is no longer searching for symptoms as it focuses on the source of the problem. This allows it to work much faster and stop post before anyone will click on it. To achieve it Facebook team manually classified tens of thousands of clickbait like headlines in order to teach algorithm how they are composed and be able to distinguish them from content shared by legitimate publishers.

The system identifies which post is a clickbait and from to which domain it is linked to. Thanks to it punished are both posts itself but also a publisher. Pages and headlines that often use clickbait headlines will appear lower in News Feed.

In order to protect algorithm from reverse engineering and eventually overcoming it, Facebook will not reveal guidelines on how it is defining clickbait. It should motivate legitimate publishers to use headlines which do not withhold information allowing to understand what is the content of an article.

I hope it will motivate legitimate publishers to name their articles correctly as I saw that even popular new sites are starting to use headlines which do not reveal the content only luring us to click on them in order to find out what it really is about.

How do you like the new algorithm? Do you think it will be successful and long-lasting change?
