NCIS has been one of my favorites. Can’t keep my interest up in re-runs forever though (which is what we get were I am).

There are certain basic scientific rules that aren’t violated when you switch the form of implementation. Pattern recognition is one of those things I focused on as a student; and even though I did different things in the real world, there were plenty of bits of scientific wisdom from that part of my education that served me well.

Just to bring you up-to-date, there are now techniques using genetic programming, sometimes combined with neural networks that do quite well.

Also, consider the fact that you - as a human - automatically notice things in your peripheral vision that grab your attention: a highly effective sort of early warning system. You don’t have to be staring right at something that should get your attention and thinking consciously about it. You don’t have to look at it clearly and for a long time, studying the many subtleties to have your early warning (sort of, it doesn’t only apply to bad things) alarm tripped.

This has led to some interesting experiments in improving recognition by actually reducing - filtering - the information being processed. Counter-intuitive; but it’s improved reliability - and it’s faster of course.

Last night was the season premier of NCIS.

I understand that I am not on the cutting edge of self-teaching software, but I’m afraid I will remain skeptical on its utility in aerospace.

The very concept of “develop (ad hoc), decouple, and thoroughly test” is well below the minimum requirements for process as they are currently written. I don’t see that changing any time soon - and I am on the committe working on the next generation of guidance on the subject.

To my knowledge, there have been very few aircraft incidents caused by software. I think I heard of a single one, but human memory is frail. To radically change what works - what makes for a high degree of safety in the fielded systems - doesn’t make all that much sense, especially when doing so requires adoption of unproven technology.

And, before you protest my choice of the word “unproven”, consider that the aerospace industry is just now coming to grips with OOT. We’re behind the times, but people stay alive...

Have a great day, Roger.
