What Generative AI Is Based On

Generative AI works by using advanced machine learning techniques, especially deep learning and neural networks, to make new content based on patterns it learns from existing data.

Generative AI starts by gathering and preparing extensive datasets containing text, images, audio, or other relevant content for training. The quality and diversity of these datasets are key for performance.

Next, specific neural network architectures generate new data:

• GANs (Generative Adversarial Networks) use two networks, a generator and a discriminator, to create and assess content, getting better through adversarial learning.
• VAEs (Variational Autoencoders) compress input data into a latent space to produce various versions of the original content.
• Transformers, such as GPT, handle and generate text sequences, making them perfect for natural language processing tasks.
• RNNs (Recurrent Neural Networks) manage sequential data by retaining input history, which is essential for tasks like language modeling and speech recognition.

During training, models learn patterns from data and adjust parameters to minimize errors and enhance content quality:

• GANs refine content by iterating between generation and discrimination until outputs resemble real data.
• VAEs optimize data reconstruction while ensuring meaningful latent space representation.
• Transformers predict text sequences to generate coherent and relevant content.
• RNNs use backpropagation through time to capture sequential relationships, that's vital for tasks involving ordered data.

Once trained, generative AI produces new content based on learned features and user input parameters. Human evaluation and feedback refine the outputs.

So, if you decide on gen AI use cases in your apps, note that you will need different models and algorithms to create specific content. Plus, the integration of this advanced tech will require knowledge of how to pick a versatile and effective generative AI stack.
