thank you for the introduction Riya we're excited to be giving this tutorial on meta learning throughout the tutorial we encourage you to be thinking about questions that you might have about the content that we're presenting and as you go through if you have a question you may come up to one of the four microphones but also if you want to also ask a question from from your own seat without having to get up we have a link for that will allow you to post questions and to also upload other questions and we'll be monitoring that
