Sometimes there are times when you read something that makes you consider the future in a very poor light. Having this particular program made publically available at this early stage of development is also a cause for concern of how skewed the world will become in the near future.
Many people will have by now at sometime in their adult life joined , have a close friend or family member that has experienced one of the online dating services. The services generally rely heavily on the basis of instant attraction. In many, you are presented with a visual of the person before any details of the personality are supplied to the browser.
Again on the visual impact, the browser can choose to like / skip etc.
Think now to the newly released python script, from Charles F. Jekel and Raphael T. Haftka of the University of Florida [arXiv:1803.04347 [cs.CV]], that based on just 20 of your likes is able to build a generic facial representation, which when applied to further images has an accuracy of 60% of knowing if you will like that image.
Once trained on 406 profiles, where each like represented a different classifier, it was over 70% accurate. Being one of the first algorithms in the area, accuracy is likely to improve over time. The question being then is where will this lead ?
Will you be able to take your liking profile from one supplier and use them with another. The reality of how oddly familiar this all seems, think about where else your liking data is used for marketing. Marketing teams will see the usefulness of this data being collected. Will the privacy agreement you’ve signed protect you liking data. The company you use could use that data for their own purposes as long as it is in their privacy agreement.
Fast forward a few years, and every website you visit could be presented by a computer generated personna that is facially configured to match your dream person. How could you resist not purchasing 63 pallets of widgets that you really don’t need just because you want to please them.
During the rise of computers we were wowed by the amazing graphics and realism that slowly grew as processors became more powerful. Soon the realism will not be realism but a distortion of reality based on our dreams and desires.
Back in reality however, it may just be time to think twice about how you let companies use your data, not all of your data is input by you on a clearly laid out form. Your data is how you navigate, how you interact, how you choose, what you look at. Under GDPR companies must release all your data they collect about you to you, and must tell you how they are processing it.

It’s not something you’re likely to be thinking about as you wandered around the supermarket at the weekend picking up groceries. However, maybe just maybe you were potholing in a dark cave somewhere in the Pennines, just then you may have thought to yourself how agile you have to be, and how many different ways there are of getting from A to B, and how careful you have to be about getting stuck in a corner.
By now you may be drawing parallels with IT and how that sounds amazing similar, be assured there are companies out there that can help you with that, but back on track to where this blog was going, which was to an off world object, be it moon, mars, asteroid.
You’ve probably seen the amazing Nasa mars lander photos of the surface, not to mention a few conspiracy theory add ons and alien sighting add ons, what lies below the surface is still something of a mystery. What is known is that there are caverns, and possibly lava tubes, now place yourself into theory mode, and consider how you would explore those tubes remotely.
Seeing the picture of the rover from Nasa doesn’t do justice to its size, and simply driving into a tunnel won’t help as there’s no light for recharging, no knowing how deep you might need to drop down, and once in unlikely to be able to transmit a signal back to earth.
Well the people, Himangshu Kalita, Steven Morad, Aaditya Ravindran, and Jekan Thangavelautham from the University of Arizona and Arizona State University have released their paper ( Path Planning and Navigation Inside Off-World Lava Tubes and Caves, 2018) on just those considerations.
The team produced a theoretical paper with some amazing ideas on how to overcome these issues and explore the caverns. Their SphereX bouncing robots will communicate back to a base station, carrying mirror tiles, which will be laid down to bounce a laser light from the rover outside for light, communications and power, they demonstrate how serious things can really look fun, and inspire the fact that space exploration once again is having a ball.
The algorithms and technology that they have for 3D mapping of tunnels with multi hopping robots, and their “TransFormer” strategy for recharging their robots deep inside a cave, can not be done justice in a short blog post.
Hop over and download their paper for yourself https://arxiv.org/ftp/arxiv/papers/1803/1803.02818.pdf
Have an inspired week ahead, everything we do here today brings us closer to being there tomorrow
