Abstract

fetched live from OpenAlex

Recent advancements of deep learning (DL) techniques have revolutionized various fields such as computer vision, image processing, artificial intelligence, and natural language processing. One notable application that showcases the power of these algorithms is the field of image synthesis, where new images are created from textual descriptions. Generative models play a crucial role in this process, enabling the generation of novel data based on patterns learned from the training set. Diffusion models are a distinctive class of generative models that operate by introducing random noise to existing data, and subsequently learning to reverse this diffusion process. This technique is particularly valuable in scenarios where the transformation of data over time or through sequential steps is a critical aspect of the generation process. The ability to translate textual descriptions into visual representations offers new possibilities for human-computer interaction and creative expressions. This paper provides a comparison and analysis of generative adversarial networks (GANs) and diffusion models within the domain of “text-to-image generation” to understand the strength and weaknesses of different models in specific contexts. For this purpose, we are using a combination of Vector-Quantized GAN (VQGAN) and Contrastive Language-Image Pre-training (CLIP) model. This combination provides a powerful integration of two distinct machine learning (ML) techniques for the purpose of creating images from textual input. Guided Language to Image Diffusion for Generation and Editing (GLIDE) is the diffusion model used in this study. For both models, text input from the MS-COCO data set is used. Evaluation of generated images is performed using Fréchet Inception Distance (FID) and Inception Score (IS) metrics. Semantic object accuracy score (SOA) is also used as a metric to add an additional layer for analysis by considering the relevance of the generated images to the provided captions during the image generation process. This metric is helpful not only to assessing visual quality of the generated images but also their alignment with the intended semantic content.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
