The Rise of Generative AI in NLP
Generative AI or AI-generated content, a subset of AI, pertains to models designed to generate new content based on the data they have been trained on.Rather than just making predictions, these models can produce unique output that could include text, images, music, and even videos.The idea behind generative AI traces back to the 1950s [7].Initial models, such as Markov models [8] and Gaussian mixture models [9], generated sequential data [7].
In the more modern era (2013), the paper by Kingma and Welling [10] introduced variational autoencoders as a form of generative models.Variational encoders learn to compress high-dimensional data into a lower-dimensional space and generate new similar data.They used Bayesian inference for the probabilistic representation of data, thereby enhancing the efficiency and effectiveness of data generation.Another popular method for generative models is generative adversarial networks, introduced by Goodfellow et al [11] in 2014.Generative adversarial networks consist of two neural networks, a generator and a discriminator, that work against each other to generate new synthetic instances of data.
In the context of text generation, transformers have now emerged as a leading architecture.Introduced in the paper "Attention is All You Need" by Vaswani et al [12] in 2017, transformers have since been the foundation of models like ChatGPT by OpenAI [1].Transformers leverage an attention mechanism that weighs the relevance of input data points and allows the model to consider the entire sequence of data at once, leading to improved context awareness in generated outputs.
At the heart of generative NLP are language models.These models predict the likelihood of a sequence of words appearing in each language.In recent years, multimodal large language models trained on vast amounts of text from the internet have become state-of-the-art for many NLP tasks.ChatGPT, an instance of the generative pretrained transformer model, has been making substantial strides.Trained on an extensive corpus of text from the internet, ChatGPT generates humanlike text based on the input provided.It serves as a testament to the rapid advancements and potential of generative AI and NLP.
As these models continue to evolve, their potential uses expand, presenting exciting opportunities across various fields.Generative AI models like ChatGPT represent an exciting frontier for medicine.As these models evolve, they hold increasing promise as tools for processing and interpreting vast, complex data sets, opening new avenues for research and clinical practice.
