Fighting Spam on YouTube with TensorFlow & Python Simply Explained 2021-06-25 | I'm sick of crypto-related spam comments on YouTube, so I trained a machine learning model to delete them! A script runs periodically and uses the text classifier to filter the latest comments on my videos.The filter is surprisingly effective, even though the training dataset is relatively small. I'll keep expanding the dataset and retrain the classifier so it becomes more accurate overtime.💌 Sign up for Simply Explained Newsletter:newsletter.simplyexplained.comMonthly newsletter with cool stuff I found on the internet (related to science, technology, biology, and other nerdy things)!

DNA Data Storage is the Future! Simply Explained 2019-06-17 | Floppy drives, hard drives and SSD's could soon be replaced by DNA storage. But why is it so much better? And what are the challenges before we can use DNA as storage media? Let's take a look!Current storage techniques have 3 problems: they are not robust, have a low density and each media requires a special reader. DNA could solve all of these problems. It's very robust (it can easily last a few centuries), it's very high density (storing many petabytes of data per gram) and we already have readers for it. 🎬Take a look behind the scenesyoutu.be/MTr2dfKtRFU📚SourcesThis video is based on the work/research of others.
