If you are a missile and you know where you are, you can express your like or dislike (whichever is greater) as an engagement action on this video. The KZread algorithm uses like and subscribe counts to generate corrective commands that drive a video from a view count that is low to a view count that is high. Consequently, the video will obtain at a like to dislike ratio that is increasing, so it follows that the dislike to like ratio is decreasing. In the event that the dislike to like ratio is not decreasing, the KZread algorithm has discovered the signal of a bad video. If the bad signal of the video is considered to be a significant factor, it may be flagged for a violation of the terms and conditions and removed from the platform entirely. However, the KZread algorithm knows everything about the audience, and it knows exactly what kinds of videos you like. It now subtracts the set of people will probably 'dislike' the video from the set of people who will probably 'like' the video, and adds the variable obtained by subtracting the set of viewers with low average watch times from the set of viewers with high average watch times. In KZread Algorithm machine learning "language", this is called 'error signal', or the difference between the expected engagement rate and the actual engagement rate, found in the algebraic difference between the number of likes, subscribes, comments and watch times of the video.

Javascript is not used for missile codes for multiple reasons - the VM imposes an extra overhead, garbage collector means performance won't be deterministic ("oh hey we're 1 second away from the target, oh no the garbage collector just paused the entire program for 0.75 seconds to do garbage collection"), and there's a lack of a compile time syntax checking and no static type system.

God as a GNC engineer for 7 years, this is sadly and hilariously spot on. There really is no other way to describe dead reckoning guidance. The video he is quoting was actually shown to me on day one. I took it as a joke. Turns out... it wasn't.

Its pretty simple. The missile knows where it is by looking at its last known position. Based on speed and trajectory it should be x distance away. When it receives another GPS ping, it gets an update to where it actually is. It compares the expected position with its actual position. If the actual position is off course, then it maneuvers the missile to eliminate the error.

Thank you so much I’ve been searching for a good tutorial on this topic!! Very enlightening!! Great video 👍

The missile knows where it is at all times. It knows this because it knows where it isn't. By subtracting where it is from where it isn't, or where it isn't from where it is - whichever is greater - it obtains a difference or deviation. The guidance subsystem uses deviations to generate corrective commands to drive the missile from a position where it is to a position where it isn't, and arriving at a position that it wasn't, it now is. Consequently, the position where it is is now the position that it wasn't, and if follows that the position that it was is now the position that it isn't. In the event that the position that the position that it is in is not the position that it wasn't, the system has acquired a variation. The variation being the difference between where the missile is and where it wasn't. If variation is considered to be a significant factor, it too may be corrected by the GEA. However, the missile must also know where it was. The missile guidance computer scenario works as follows: Because a variation has modified some of the information that the missile has obtained, it is not sure just where it is. However, it is sure where it isn't, within reason, and it know where it was. It now subtracts where it should be from where it wasn't, or vice versa. And by differentiating this from the algebraic sum of where it shouldn't be and where it was, it is able to obtain the deviation and its variation, which is called error.

As a missile, I thank you for the assistance, as I am new to the "literally fucking obliterating an area" community

The dude went to explain how a guidance system works. But he kept it absolutely abstract without using any math and using purely english words. In the hopes of making it so someone doesn't need high school algebra and a few variable definition, making it clear to anyone who could have understood it. He made it clear to noone except those who already knew how it worked (or had an inkling/experience) and reverse engineered his words.

I'm working on a guided missile on a simulator to build it in real life (with a catching net) to shoot down drones, as a prove of concept, and this is actually useful

I work in the field of guidance, navigation and control for aerospace applications and this tutorial is very accurate.

This is a total rocket science for me... ...But at the same time it's finally somewhat easier to understand, and I learn better by seeing something other than hearing. It's really easier when it's written down.

I both love that you made the code for this, but I also hate it because it makes it less funny actually being able to understand what it was doing

If you program this in COBOL and put a mainframe inside the missile, no warhead is needed.

there's one thing to consider: once the missile finished the calculation, it is already somewhere else. from this it follows that the missile never is there where it "thinks" it is at any given moment in time.
