My Machine Learning keynote address to participants at DevFest Nairobi 2022. I focused on the history of ML, the fact that the field nearly didn't exists, the AI Winter, the factors that finally made neural networks possible, what ML is used for within and outside Google, and the tools that Google makes available in order to enable and democratize ML. These tools include TensorFlow and TFLite, DialogFlow (for building conversational user interfaces, or chatbots), ML Kit (for mobile applications), Cloud APIs, AutoML, VertexAI, and MediaPipe, among others.
