A Random Walk(*) with Artificial Intelligence (by Paul W. Smith)

January 13, 2020

 My wife and I recently joined some of the last homeowners to contribute to the $11 billion robot vacuum industry.  Since I am usually the one who does the vacuuming, I liked the idea of completing this chore with the simple push of a button.  It was an exciting day when I took our new Roomba out of the box, placed it on it’s little charging dock (which we located in the laundry room for our convenience), and then stood back and pressed “Clean” on my iPhone app.  

 

Our Roomba (which we named “MaxBot”) banged up against the dryer a few times, then headed off down the hallway toward the living room.  Our 13-yr old Shih Tzu soon began barking frantically, having failed to grasp the utility of this intruder.  At his age, the only thing he does frantically anymore is eat; it was clear that a black hockey puck bigger than he is should not be scooting around the house unattended – at least not on his watch.  Lesson #1:  AI robots are not for everyone.

 

According to the promotional literature, robot vacuums use Artificial Intelligence to map out and store the boundaries of your home, calculating the most efficient way to cover every square foot.  They are also supposed to anticipate their own demise, returning to the home base and recharging when needed. 

 

On the morning after the first trial run, I awoke expecting to find a bunch of neatly vacuumed rows, like the freshly mowed patterns on a major league baseball field.  I assumed the robot would be back in the laundry room, with full batteries and eagerly awaiting its next cleaning assignment.  Instead, MaxBot was cowering guiltily under the dining room table and the living room looked as if it had been run over by a drunk monkey.  While I was peacefully dreaming of things unrelated to household chores, MaxBot had texted a desperate message to my phone, pleading for a charge.  The laundry room base station was the most convenient for us, but not for MaxBot which was unable to find its way back there.  Lesson #2:  AI will require some accommodations. 

 

The naturally intelligent folks at Stanford have studied the impact of emerging AI developments on robotics, predicting that by the end of the next decade, domestic robots like ours will be much more common.  They noted that current robot vacuums don’t do stairs, while the majority of homes have one or more of them (MaxBot will tip over about 30 degrees at our top stair before altering course in search of level ground).  Those same folks who tape over the little camera on their laptop computer have also expressed concern that robotic vacuums contain valuable data about the size and floor-plan of our rooms, coupled with the geo-location of the home.  Stanford NI believes these, and other problems, will eventually be overcome.

 

One of the most puzzling aspects of AI in many of its applications is that it can be hard for even the developers to understand what it’s up to.  Algorithms based on self-learning, neural networks, or deep learning can make AI smarter without revealing exactly how it got that way.  One example from the medical field was recently reported in New Scientist.

 

If your cardiologist diagnoses you with a serious incurable heart problem, you would understandably want to know just how much time you have left.  Doctors expect this question and will make a reasonable and compassionate effort to answer it.  Meanwhile, scientists in a Pennsylvania healthcare group have been evaluating an AI solution.

 

In order to avoid the inevitable ethical questions, their AI test system was given electrocardiogram data for patients whose date of demise was already known.  The researchers not only found that the AI was much more accurate than the cardiologists in its predictions, it also forecast the risk of death in patients previously classified as having a normal ECG.  Although this new AI technology can tell you when you will die, no one is quite sure how it knows.

 

All of which leads to the most important lesson of all, Lesson #3:  Don’t expect too much from technology, especially one that cleans like a drunk monkey.
