Engineering Features from Network Traffic

Flow-level features, duration, packets per second, packet size statistics, byte ratios, and TCP flag counts, that summarise raw packets into the fixed numeric vector a model can actually learn from, with a runnable summarisation function.

Engineering Features from Network Traffic

Raw packet captures are not features; they are bytes on a wire. A network flow has to be summarised into a fixed-length numeric vector before any model ever sees it.
