The second approach, called Representation-Aware, assumes that such knowledge is known and uses it for error correction. Furthermore, both approaches combine the decoding based on NR and ECCs. ...
It uses deep learning to detect file types accurately, and then mine Natural Redundancy for soft decoding. ...
In practice, it is worthwhile to study the properties of Natural Redundancy (e.g., whether the redundancy is mainly local or global, which differs for different types of data), and choose appropriate coding ...
