Les Atlas

  • Professor, Electrical Engineering
  • Adjunct Professor, Computer Science and Engineering

Les Atlas joined UW EE as an assistant professor in 1984 at the University of Washington. He has been a leader in signal processing research and educational activity in the Pacific Northwest, co-chairing the IEEE International Conference on Acoustics, Speech, and Signal Processing in 1989 with Xuedong Huang of Microsoft.

Atlas’ research has had an impact on signal processing for dynamical systems, time-frequency analysis and nonstationary statistics, with applications in streaming data, acoustics, machine monitoring, sensor arrays, speech processing and auditory sciences. His publication “Improving generalization with active learning” was foundational to the machine learning areas of active learning and selective sampling.

Atlas’ graduate students have also had tremendous impact — such as the first publication on trained (linear) convolutional neural networks for temporal signals, securing top faculty positions, initiating machine learning at Google, receiving multiple Technical Emmy Awards and founding companies such as Redfin.

Atlas’ research is funded by the Army Research Office, the Office of Naval Research and the Wallace H. Coulter Foundation.
