Structured Prediction

# Log-time and Log-space Extreme Classification

Introduced by Jasinska et al. in Log-time and Log-space Extreme Classification

LTLS is a technique for multiclass and multilabel prediction that can perform training and inference in logarithmic time and space. LTLS embeds large classification problems into simple structured prediction problems and relies on efficient dynamic programming algorithms for inference. It tackles extreme multi-class and multi-label classification problems where the size $C$ of the output space is extremely large.
