The demand for data scientists is rising at an incredibly fast pace, as well as their salaries. Data scientists command very high salaries, and their services are much in demand by different types of businesses. The ability to read and synthesize data is a skill that many people don't have. This doesn't come naturally, it takes discipline and a lot of hard work. Every company is looking for a data scientist. You're probably familiar with buzzwords like Hadoop, R, Python, SQL, and maybe even Spark — but what about all the other skills that you need to master? Well, you

Given that these cameras are operating in busy urban environments, they're often triggered over 100,000 times a day. the captured footage could just show a passing car or pedestrian, so why, then, aren't the council getting thousands of alerts a day? how is the camera able to spot a legitimate fly—tipping event amidst all that noise? well, the magic isn't actually happening in the camera itself, but rather behind the scenes in the cloud. there's an ai, machine—learning element to the process. how does that work and what are the cameras looking for? detection of people is reasonably straigh...

Environment. the cameras collect a lot of date of movement in the environment. data scientists will look at that and make sure we tag and review the footage and making sure the right thing is being tagged, are we getting false positives or false negatives? trying to minimise those elements so that what we see is accurate. so you're actually using a little bit of a human element to teach them context. that's quite a difficult thing for an al to learn on its own. vision technology can identify what a box is or what a mattress is, but it doesn't know whether that's good or bad. i can see shadowy ...

The data science industry is facing a lack of experienced candidates, Insider spoke to experts to find out what they look for in new recruits.

Amidst all that noise? well, the magic isn't actually happening in the camera itself, but rather, behind the scenes in the cloud. there's an aland machine learning element to this process. how does that work and what are the cameras doing and what are they looking for? detection of people and that sort of thing is reasonably straightforward, and the cameras will do that themselves. what is the tricky bit is — what is rubbish? it's quite an objective thing, isn't it? yeah. rubbish in one environment is not rubbish in another environment. the cameras are installed, they collect a log of data o...
