What's a minimum sample size you've been successfully using? I'd imagine that finding APKs, disassembling them and finding the malware yourself for the training datasets are rather resource intensive tasks, so it's a difficult balancing act?
- wolfos 9y agoWe did an experiment where we vary the number of training samples and measure validation accuracy (Fig. 3). Basically, the system keeps getting better as you give it more data. (For good real world performance I'd say 10s of thousands of training samples would be needed). Initially, we were using an off the shelf dataset donated by an anti-virus company. Later we did some experiments using a much larger dataset collected by our colleagues at ASU. Although I was not involved with collecting that dataset, as far as I know the Android APKs were scraped from various online stores and checked for malware using virustotal.com
