FLD+: Data-efficient Evaluation Metric for Generative Models

1 code implementation23 Nov 2024 Pranav Jeevan, Neeraj Nixon, Amit Sethi

We introduce a new metric to assess the quality of generated images that is more reliable, data-efficient, compute-efficient, and adaptable to new domains than the previous metrics, such as Fr\'echet Inception Distance (FID).

Evaluation Metric for Quality Control and Generative Models in Histopathology Images

no code implementations1 Nov 2024 Pranav Jeevan, Neeraj Nixon, Abhijeet Patil, Amit Sethi

Our study introduces ResNet-L2 (RL2), a novel metric for evaluating generative models and image quality in histopathology, addressing limitations of traditional metrics, such as Frechet inception distance (FID), when the data is scarce.
