Research on CNN architectures has progressed extremely dynamically. Several developments are of potential interests in the context of trading strategies that use alternative data, especially image data.
Recent developments
Fast detection of objects on satellite images
Kaggle recently conducted a competition to detect container ships on satellite images, emphasizing fast inference. Prominent architectures included UNET, which has been used in bioinformatics (see GitHub: https://github.com/PacktPublishing/Hands-On-Machine-Learning-for-Algorithmic-Trading for references).
