Answer
A. Generative AI creates content while discriminative AI classifies data.
Explanation
The difference between generative AI and discriminative AI is A. Generative AI creates content while discriminative AI classifies data.
Generative AI and discriminative AI are two broad categories of machine learning models that have different goals and methods.
Generative AI models are those that try to model how data is distributed and can generate new data of the same type, while discriminative AI models are those that try to differentiate between existing data and can classify data into categories.
Generative AI models work by:
- Learning the joint probability distribution of the input and output variables, such as p(x,y), where x is the input and y is the output.
- Sampling from the learned distribution to create new data instances that resemble the original data, such as x’ or y’.
- Performing tasks such as data augmentation, data synthesis, data completion, or data transformation.
Discriminative AI models work by:
- Learning the conditional probability distribution of the output variable given the input variable, such as p(y|x), where x is the input and y is the output.
- Predicting the output variable for a given input variable based on the learned distribution, such as y’ for x’.
- Performing tasks such as classification, regression, or detection.
Some examples of generative AI models are:
- Generative adversarial networks (GANs), which use two competing neural networks to generate realistic images, text, or audio from noise or latent variables.
- Variational autoencoders (VAEs), which use a neural network to encode the input data into a latent space and then decode it back to generate new data similar to the input.
- Hidden Markov models (HMMs), which use a probabilistic graphical model to generate sequences of data based on hidden states and transitions.
Some examples of discriminative AI models are:
- Support vector machines (SVMs), which use a linear or nonlinear function to separate the data into different classes based on a margin.
- Logistic regression, which uses a logistic function to model the probability of a binary outcome based on one or more input variables.
- K-nearest neighbors (KNN), which use the distance between the input and the training data points to assign a class label based on the majority vote of its neighbors.
