The talk will cover exciting and recent developments in the world of AI-generated art as well as live musical demos! #### Speaker Bio: Lamtharn (Hanoi) Hantrakul - AI Resident, Google Brain Hanoi - like the towers? No. Like the city? Yes! Hanoi's Thai parents fell in love there and nicknamed him after the charming city. Born and raised in Bangkok, Thailand, he is currently an AI Resident with Google Brain. His research focuses on real-time Neural Audio Synthesis: rendering sound directly using deep neural networks. Hanoi strives for technologies that are transcultural at heart; diversifying software, hardware and AI to encompass underrepresented cultures such as those from his home region of Thailand and beyond. He is most proud of fidular, a modular fiddle system he designed and engineered that enables components like resonators and strings to be swapped across cultures. The system is currently on display at the Musical Instruments Museum in Phoenix, AZ, and has been recognized internationally by the A’ Design Award and Core77 Design Award. Hanoi hold degrees in Applied Physics and Music Composition, both with Distinction from Yale University. In his MSc thesis at Georgia Tech, he developed machine learning models for an ultrasound sensor that enables amputees to perform high-dexterity tasks like playing piano; an impossible feat using today’s sensors on conventional prosthetics. He also writes music under the moniker "yaboi hanoi". Find his tunes on Instagram and Spotify!
