Trustworthy Machine Learning Lab (TML Lab) at the University of Sydney hosts, attracts, and connects the best global talents to develop trustworthy machine learning techniques and tools, which are explainable, robust, fair, causally responsible, and privacy-preserving. Our mission is to make machines trustworthy, which is a foundation for our society to develop and deploy artificial intelligence to improve our lives. We are broadly interested in the fields of trustworthy machine learning and its interdisciplinary applications, with a particular emphasis on learning with noisy labels, adversarial learning, transfer learning, unsupervised learning, and statistical deep learning theory.
We are recruiting PhD and visitors. If you are interested, please send me your CV and transcripts.
A few visiting positions in machine learning and computer vision are available.
