Explore the fascinating world of Viking runes and deep learning in this 47-minute Devoxx conference talk. Dive into the Younger Futhark writing system and learn how to build a Convolutional Neural Network using Keras to recognize hand-written runes. Follow along as the speaker demonstrates the creation of a web application with Flask and JavaScript, allowing real-time rune recognition. Gain insights into the workings of Convolutional Neural Networks, their visual hierarchy, and practical implementation using Python and Keras. Discover the potential applications of this technology, from ancient scripts to modern symbols like the Bluetooth logo. By the end of the talk, acquire the knowledge to construct your own neural networks and integrate them into applications using Flask.
