TACTIC: Joint Rate-Distortion-Accuracy Optimisation for Low Bitrate Compression [article]

Nikolina Kubiak, Simon Hadfield
2021 arXiv   pre-print
We present TACTIC: Task-Aware Compression Through Intelligent Coding. Our lossy compression model learns based on the rate-distortion-accuracy trade-off for a specific task.  ...  By considering what information is important for the follow-on problem, the system trades off visual fidelity for good task performance at a low bitrate.  ...  Rate-distortion-accuracy trade-off (TACTIC) Figure 2 : 2 Accuracy vs bitrate curves for TACTIC and models trained with JPEG-compressed data. sum of both; γ was used as a scale factor on the Dice loss  ...

Communication and cooperation in evolutionary biology [article]

Stephen Mann, University, The Australian National
These criticisms lend support to scepticism about the relevance of information for evolutionary biology.  ...  It is common in the philosophy of biology to treat the concepts and tools of communication theory as insufficient or irrelevant for analysing semantic [...]  ...  For example, truly cooperative signals that are not threatened by defection should be optimised for low energy expenditure.  ...
