Fine-tuning text-to-image generative AI models by Maciej Mackiewicz

The presentation will cover how to fine-tune a Stable Diffusion text-to-image model on custom data. Besides regular fine tuning, we will go over Low Rank Adaptation method that can speed up the training time and greatly reduce the size of fine-tuned artefact.

About Maciej:

Senior Machine Learning Engineer at Nike with seven years of experience in software development, machine learning engineering and MLOps. Alumni of Big Data studies at Warsaw School of Economics. Most passionate about working with text data.

Introducing Optuna – next-generation hyperparameter optimization by Mateusz Serocki

The presentation will be about the Optuna package that allows you to tune model hyperparameters in optimal time. We will compare that solution to other most common approaches. During that part, we will also see how Optuna can visualize results and we will talk about the interpretation of those visualization. As a final step, you will learn how to use Optuna for tunning neural network structure and optimization algorithm.

About Mateusz:

I’m Senior Machine Learning Engineer at NIKE. Throughout my carrier I was working on various topics, mostly demand forecast, classification, and regression problems. I’m fully focusing on a deep understanding of math that stands behind the machine learning algorithms.
