Comment on Programmer tries to explain binary search to the police
CosmicCleric@lemmy.world 10 months agoHaving an AI search for shapes an opaqueness is still totally useless for a binary search if those semi-opaque shapes happen for 10 minutes 34 minutes into an hour long video
Well one of those shapes would happen at the time of the event though, so it’s not useless. One of those would be a gunshot smoke, and could be flagged for review.

The time of the event doesn’t necessarily coincide with any of the times that you’re checking. That’s the whole point of looking for visual cues instead of trying to pinpoint the event. Again, if the event happens 34 minutes into the video, and it leaves AI detectable visual cues for 10 minutes, the AI will never find it using binary search. It will skip to 30 minutes, see nothing, skip to 45 minutes, see nothing, skip to 52:30, see nothing, skip to 56:15, see nothing, and fail at some point when it can’t divide the video further. Binary search would fail in this scenario. It’s not just useless, it’s an abject failure, and the AI was a waste of processing power when you could have scrubbed forward five minutes at a time instead. That would have found the visual cue, but would not be a binary search.

But one of them potentially will though. A gun firing leave smoke behind.
Even if there’s other smoke in the video, you’re looking at 5 minutes of a 24-hour video, and not scanning through 24 hours of a video manually. And an AI could use a binary search to find any moments of smoke (or not). Not saying it’s a one-size-fits-all solution, just one very important tool in a toolbox.
I don’t mean to be rude, but I’m exhausted talking about this topic, and so if you don’t mind, I’m just going to bail at this point.
Thanks for keeping it civil.

It’s… No. If we’re talking about a 24 hour video, then we definitely can’t find every instance of smoke. If there isn’t any smoke 12 hours into the video, then it throws away the entire first 12 hours. Any evidence that could have been found in those 12 hours is gone. A binary search throws away half of the information at a time. It super can’t locate multiple instances of something happening.
I’ve been wrong in arguments before, it feels awful. The best things to do are either address the misunderstanding in the original comment, or turn off notifications until people lose interest in the thread.

Well, I’m not wrong, so I don’t worry awful it from that angle. Just feel that people are not arguing/conversing in good faith.
The misunderstanding of others assuming differently than I was discussed elsewhere in the comment thread. To reiterate, I believe my assumptiion is the correct one based on how the world is, and not hypotheticals.
As far as not arguing more, it gets to a point of where some moderation should be happening, because its pretty evident at some people that people are group thinking attacking someone just for the lols if nothing else, and I say that because when I explain why I don’t think I’m wrong they don’t answer my point, but instead just insert their own new points in the conversation.
Otherwise, I feel the need to defend myself, especially when people say I’m saying things I’m not saying. “Standing up to bullies” sort of attitude. It sucks, but Humanity can be assholes sometimes.
I’d really like to stop talking about this now, I’d appreciate you not responding to this comment, unless you really feel the need to. Take care.
