?It is gen AI when the output is natural language, like speech?or text, an image or audio.
So the model output is a function of all the inputs.?If the y is the number, like predicted sales,?it is not gen AI
If y is a sentence, like define sales,?it is generative as the question would elicit a text response.?The response would be based on all the massive large data?the model was already trained on.
To summarize at a high level, the traditional, classical?supervised and unsupervised learning process?takes training code and label data to build a model.?Depending on the use case or problem,?the model can give you a prediction.?It can classify something or cluster something.
We use this example to show you how much more robust?the gen AI process is.?The gen AI process can take training code, label data,?and unlabeled data of all data types?and build a foundation model.?
The foundation model can then generate new content.?For example, text, code, images, audio, video, etcetera.?
We've come a long away from traditional programming?to neural networks to generative models.?
In traditional programming : we used?to have to hard code the rules for distinguishing a cat--?the type, animal; legs, four; ears, two; fur, yes;?likes yarn and catnip.
In the wave of neural networks: we?could give the network pictures of cats and dogs?and ask is this a cat and it would predict a cat.
In the generative wave: we as users?can generate our own content, whether it?be text, images, audio, video, et cetera.
In the generative wave example?models like PaLM or Pathways Language Model,?or LaMDA, Language Model for Dialogue Applications,?ingest very, very large data from the multiple sources?across the internet and build foundation language?models we can use simply by asking a question,?whether typing it into a prompt or verbally?talking into the prompt itself.
So when you ask it what's a cat, it?can give you everything it has learned about a cat.?Now we come to our formal definition.?
What is generative AI??Gen AI is a type of artificial intelligence?that creates new content based on what it has?learned from existing content.?The process of learning from existing content?is called training and results in the creation?of a statistical model when given a prompt.?AI uses the model to predict what an expected response might?be and this generates new content.
Essentially, it learns the underlying structure?of the data and can then generate?new samples that are similar to the data it was trained on.?As previously mentioned.
Large language models are one type of generative AI?since they generate novel combinations of text?in the form of natural sounding language.
