IMPARO: inferring microbial interactions through parameter optimisation [PDF]

BMC Molecular and Cell Biology, 2020
Background Microbial Interaction Networks (MINs) provide important information for understanding bacterial communities. MINs can be inferred by examining microbial abundance profiles. Abundance profiles are often interpreted with the Lotka Volterra model

The disparity between optimal and practical Lagrangian multiplier estimation in video encoders

Frontiers in Signal Processing, 2023
With video streaming making up 80% of the global internet bandwidth, the need to deliver high-quality video at low bitrate, combined with the high complexity of modern codecs, has led to the idea of a per-clip optimisation approach in transcoding.
