5. Training Paradigm
ML models typically follow supervised or unsupervised learning paradigms. Supervised learning involves using clear data examples with answers or feedback to learn the relationship between input and output.
The training process involves adjusting model parameters to minimize a predefined loss function, which measures the disparity between predictions and actual outcomes. This is a crucial step in ensuring the model learns from its mistakes.
Expand your knowledge: Supervised or Unsupervised Machine Learning Examples
Generative AI models often rely on unsupervised or self-supervised learning approaches. These approaches allow the model to learn from data without explicit labels or feedback.
Adversarial training techniques, such as GANs, can also be used to improve the quality of generated samples. In GANs, two neural networks compete against each other to produce better results.
Modalities
Generative AI systems can be trained on various data sets, including audio clips, to produce natural-sounding speech synthesis and text-to-speech capabilities.
These systems can be trained extensively on audio waveforms of recorded music along with text annotations to generate new musical samples based on text descriptions.
A generative AI system is constructed by applying unsupervised machine learning to a data set, and its capabilities depend on the modality or type of the data set used.
Generative AI can be either unimodal or multimodal, with unimodal systems taking only one type of input and multimodal systems accepting more than one type of input.
For example, one version of OpenAI's GPT-4 accepts both text and image inputs, showcasing the multimodal capabilities of generative AI systems.

Actions
Generative AI can be trained on the motions of a robotic system to generate new trajectories for motion planning or navigation.
UniPi from Google Research uses prompts like "pick up blue bowl" or "wipe plate with yellow sponge" to control movements of a robot arm.
Multimodal "vision-language-action" models such as Google's RT-2 can perform rudimentary reasoning in response to user prompts and visual input.
These models can be used to control robots to perform tasks like picking up a toy dinosaur when given the prompt to pick up the extinct animal at a table filled with toy animals and other objects.
Input vs Output
In Machine Learning, the quality and reliability of outputs depend heavily on the input data quality and features extracted during training.
The focus lies in optimizing models for accurate results rather than generating entirely new information.
Generative AI operates differently by utilizing random noise as input to generate outputs that exhibit characteristics learned from training data.
This approach allows for the creation of novel content that doesn't merely mirror existing input but goes beyond by creating something entirely distinctive yet coherent.
Machine Learning models are optimized for accurate results, whereas Generative AI is optimized for generating new information.
