The Challenge | Chasers of the Lost Data

Help find ways to improve the performance of machine learning and predictive models by filling in gaps in the datasets prior to model training. This entails finding methods to computationally recover or approximate data that is missing due to sensor issues or signal noise that compromises experimental data collection. This work is inspired by data collection during additive manufacturing (AM) processes where sensors capture build characteristics in-situ, but it has applications across many NASA domains.

Ark

Ark is an iterative temporal-based imputing network.

Ark is a model that captures the temporal dynamics of NASA’s sensor data through the use of an Iterative LSTM network and thus, it is generalizable to many different applications, both categorical and continuous.
