SHRED-ROM
Full name: Reduced order modeling with shallow recurrent decoder networks

SHallow REcurrent Decoder-based Reduced Order Model (SHRED-ROM) is an ultra-hyperreduced order modeling framework aiming at reconstructing high-dimensional data from limited sensor measurements in multiple scenarios. Thanks to the composition of a Long-Short Term Memory network (LSTM) and a Shallow Decoder Network (SDN), SHRED-ROM is capable of

Reconstructing high-dimensional data (such as synthetic or video data) from sparse sensor measurements in new scenarios unseen during training, regardless of sensor placement,
Dealing with both physical, geometrical and time-dependent parametric dependencies, while being agnostic to the paraemter values,
Estimating unknown parameters,
Coping with both fixed or mobile sensors.
Importantly, computational efficiency and memory usage are enhanced by reducing the dimensionality of full-order snapshots, allowing for compressive training of the networks, with minimal hyperparameter tuning and laptop-level computing.
