It's not a 20% failure rate when the chatbot routes calls to a human agent whenever it's more than x% unsure about what to say.
AI solutions still get the 80% "bottom of the barrel" menial tasks perfectly well.
It wont know it doesn't know. At the current state of AI, it doesn't seem to have almost any sense of what is right and wrong or a way to validate that - even when you tell it, it is wrong. Maybe there are systems that can but I am not aware of them.
The current state of AI chatbots, assigns a "confidence level" to every piece of output. It signals perfectly well when and where they should look for more information... but humans have been pushing them to "output something, anything", instead of excusing itself for not knowing something, or running some additional processes in order to look for the missing information.
As of this year, Copilot has been running web searches to complement its lack of information, and Gemini is running both web searches, and iteratively self-checking its own answer in order to refine it (see "drafts"). It also seems like Gemini might be learning from humanity's reactions to its wrong answers.
From my understanding, AI is a essentially a statistical method so naturally it will use a confidence level. Its hard for me to take the leap of faith to confidence level will correlate to accuracy. Seems to me it would be more dependent on its data set. If its data contains a commonly held belief, that is incorrect, would it not have a high confidence level on an answer with that incorrect info? If we use a highly authoritative data set, that will be very limited and we'd be back to more of a keyword system than a LLM. I am sure with time, we'll be in more of a middle ground where accuracy will be better but what will that be? 5% 3% 10%?
I'll freely admit I am not an expert in this at all.
It's not a statistical method anymore. One of the breakthroughs of large model neural networks, has been that during training an emergent process, assigns neurons to both relatively high level and specific traits, which at the same time "cluster up" with other neurons assigned to related traits. Adding just a bit of randomness ("temperature") allows the AI to jump from activating one trait to a close one, but not to one too far away. Confidence becomes a measure of how close is the output, to a consistent set of traits trained into the network. Interestingly, a temperature of 0 gives a confidence of 100%... but produces gibberish.
This is where things start to get weird. An AI system based on an LLM, can iterate over its own answers looking for the optimal one (Q*), and even detect inconsistencies in them. What it does after that, depends on whoever programmed it:
Over time, I think different AI systems will evolve to target accuracy, consistency, creativity, etc. Current systems are kind of rudimentary compared to what's yet to come, and too many are used in very rudimentary ways by anyone who can slap an "AI" label and sell them.
That is pretty interesting and thanks for posting it. I hear the words and its intriguing but to be honest, I don't really understand it. I'd have to give it some thought and read more about it. Do you have a place you suggest going to learn more?
I use chatgpt-4o currently for learning python and helping with grammar. I find it does great with grammar but even with relatively simple python questions it can produce some "creative" answers. Like its in the ball park but its not perfect and for a learner, that's learning the hard way. To be fair I don't use the assistant/code interpreter, which I have no idea about but based on its name I assume it might be better. So that's what I based my somewhat skeptical opinion of ai on.
Check out this one for a general overview:

You may want to also check an intro to neural networks, and Q* is a somewhat new concept. Other than that... "the internet". There are plenty of places with info, not sure if there is a more centralized and structured one.
Learning to code with just ChatGPT is not the best idea. You need to join three areas:
ChatGPT's programming answers, give you an intersection of all those, often with some quirks, with the nice but only benefit of explaining what it thinks it is doing. You still need to have some basic understanding of those in order to understand what ChatGPT is talking about, how to double-check it, and how to look for more info. It can be a great timesaver as a way to generate drafts, though.
