Introduction to Generative AI
TLDRWelcome to 'Introduction to Generative AI,' a course led by Roger Martinez, a developer relations engineer at Google Cloud. The course aims to define generative AI, explain its workings, describe its model types, and outline its applications. Generative AI is an AI technology that creates various forms of content, including text, imagery, audio, and synthetic data. It is a subset of deep learning, which uses artificial neural networks to process complex patterns. The course differentiates between generative and discriminative models, with the former generating new data instances and the latter classifying or predicting labels for data points. Generative AI models can be text-to-text, text-to-image, text-to-video, and more, and are powered by Transformers, which can sometimes produce 'hallucinations' or nonsensical outputs. Prompts are used to guide the output of generative AI models, and the course touches on the importance of training data and the potential for these models to revolutionize industries. Tools like Vertex AI Studio, Vertex AI, and the Palm API are introduced to help developers leverage generative AI in their applications. The video also highlights the capabilities of the Gemini model, which can analyze multiple data types, and the Model Garden for continuous updates on new models.
