Intersectional Fairness: A Fractal Approach

no code implementations24 Feb 2023 Giulio Filippi, Sara Zannone, Adriano Koshiyama

The problem can be approached by looking at different protected attributes (e. g., ethnicity, gender, etc) independently, but fairness for individual protected attributes does not imply intersectional fairness.

QuantNet: Transferring Learning Across Systematic Trading Strategies

2 code implementations7 Apr 2020 Adriano Koshiyama, Sebastian Flennerhag, Stefano B. Blumberg, Nick Firoozye, Philip Treleaven

The encoder transforms market-specific data into an abstract latent representation that is processed by a global model shared by all markets, while the decoder learns a market-specific trading strategy based on both local and global information from the market-specific encoder and the global model.

Augmenting correlation structures in spatial data using deep generative models

1 code implementation23 May 2019 Konstantin Klemmer, Adriano Koshiyama, Sebastian Flennerhag

We empirically show the superiority of this approach over conventional ensemble learning approaches and rivaling spatial data augmentation methods, using synthetic and real-world prediction tasks.
