1 year agoI think the main point they’re disagreeing with is this:
you wouldn’t be able to mathematically prove that the signal is perfectly recovered 100% of the time for all possible inputs
They explain why you don’t need 100% accuracy - most compression codecs would only use the network for a prediction, which doesn’t actually have to be correct. It just has to be “more likely to be correct” than existing algorithms.
If you want to read up more on the context of these prediction functions, the general class of compression algorithms you’d use for this are called prediction wavelet codecs. FLAC and arguably PNG are both prediction wavelet codecs.
Something I don’t often see people talking about this game is the ending, which probably had the largest effect on me of any game I’ve ever played.

Before I played Spec Ops: The Line, I was staunchly against suicide in all instances.
The ending puts you in a situation where you’ve more or less committed genocide (or at least horrifying war crimes), for ultimately no real cause. There’s no solution to make amends, you can’t undo what you’ve done.
It then puts you in a position where you can effectively choose to commit suicide.
If given the choice, most people would go back in time and kill hitler. But what if you WERE hitler, and suddenly realized the true implications of your actions. You were responsible for the torture and murder of millions on innocent people, actions that are impossible to forgive. Would the moral and ethical action be to kill yourself? Even if doing so wouldn’t prevent further death or harm to others?
That ending made me rethink my stance on suicide, the topic is far more complicated than I used to think it was. To this day, every now and again, I still think about the choice at that ending.
