An Introduction to the World of Generative AI
Feb 7, 2023by, Maheswari C S
ChatGPT has been causing a storm in the tech world for a while now. With debates around the corner about its efficiency, and whether it will be a threat to manual labor, let’s focus this blog on an even bigger picture. Welcome to the world of Generative AI, the concept that powers advancements in GANs (Generative Adversarial Networks), LLMs (Large Language Models), GPT (Generative Pre-trained Transformers), and Stable Diffusion Image Generation for the exploration and generation of commercial services like DALL-E and our star of the hour, ChatGPT for text generation.
Generative AI is a wide term that can be referred to as a state-of-the-art technological development using artificial intelligence and machine learning to generate new data samples similar to existing ones. These algorithms can be used to generate a wide range of outputs, such as images, videos, audio, text, and even 3D models.
Advanced machine learning techniques, such as large language models, neural translation, information understanding, and reinforcement learning, have made it possible to create original short and long-form content, synthetic media, and even deep fakes using only simple text prompts.
With the help of machine learning, Generative AI systems are built to generate new content based on their prior knowledge. For instance, ChatGPT was trained on a sizable amount of online text and dialogue scripts to mimic real-life discussions. Stable Diffusion is an AI-based image generation system that generates images based on text commands. The system was developed by feeding images and captions from the web to the AI which helps it figure out what to “illustrate” based on verbal commands.
One of the most popular generative AI algorithms is the Generative Adversarial Network (GAN). GANs consist of two main components: a generator and a discriminator. The generator produces new data samples, while the discriminator attempts to distinguish the generated samples from real ones. The two components are trained together, with the generator trying to produce samples that can fool the discriminator, and the discriminator trying to become better at identifying fake samples.
Another popular generative AI algorithm is the Variational Autoencoder (VAE). VAEs are a type of neural network that can be used to generate new data samples by encoding existing ones into a lower-dimensional space and then decoding them back into the original space. This allows VAEs to learn a compact representation of the data, which can be used to generate new samples that are similar to the original ones.
Use Cases & Limitations
Generative AI algorithms have many applications, such as image and video synthesis, image, and video manipulation, text and speech generation, and even drug discovery.
In image and video synthesis, generative AI algorithms can be used to create realistic images and videos of objects, scenes, and people that do not exist in the real world. This can generate content for movies, video games, and virtual reality applications.
In image and video manipulation, generative AI algorithms can be used to edit and manipulate existing images and videos in a variety of ways, such as changing the background, adding or removing objects, or altering the lighting and color.
In text and speech generation, generative AI algorithms can be used to generate written or spoken language that is similar to human language. This can be used to generate captions for images and videos or to create chatbots and virtual assistants.
In drug discovery, generative AI algorithms can generate new chemical compounds similar to existing drugs, but with improved properties. This can help to speed up the drug discovery process and reduce the cost of developing new drugs.
However, Generative AI comes with its fair share of limitations. One of the main challenges is to ensure that the generated data is of high quality and that it is not biased or misleading. Additionally, the models may generate data that is not coherent, and that does not make sense in the real world.
Generative AI is a rapidly evolving field with a wide range of potential applications. While there are still many challenges to be addressed, the benefits of this technology are clear, and it will likely continue to play an essential role in many areas of AI research and development in the future.
