There are 4 modules in this course

The Preparing Images for AI Models course is designed for developers, engineers, and technical product builders who are new to Generative AI but already have intermediate machine learning knowledge, basic Python proficiency, and familiarity with development environments such as VS Code, and who want to engineer, customize, and deploy open generative AI solutions while avoiding vendor lock-in.

The course provides learners with essential skills to source, prepare, and augment image datasets for training diffusion models. Learners begin by navigating public repositories such as the Large-scale Artificial Intelligence Open Network (LAION), ImageNet, and Flickr30k, evaluating datasets for quality, diversity, and legal compliance. The course then introduces preprocessing workflows, including resizing, cropping, normalization, and metadata management to enhance dataset consistency. Learners practice batch processing for large collections while applying quality checks to detect corrupted or duplicate files. The final module focuses on augmentation strategies—ranging from basic transformations to advanced techniques like CutMix, MixUp, and style transfer—to improve robustness and diversity without introducing distribution shifts. By the end of the course, learners will have developed a structured, production-ready dataset optimized for training or fine-tuning diffusion models.

Learn how to evaluate image datasets used for AI development. You’ll explore public repositories and compare datasets based on quality, diversity, and fit for different training goals. You’ll also cover critical legal and ethical considerations, and practice techniques for managing and organizing large collections to confidently select datasets that strengthen both the accuracy and integrity of your models.

Frequently asked questions

To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.

When you enroll in the course, you get access to all of the courses in the Certificate, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
