Dr Ofir Lindenbaum CV 

About me

I am a senior lecturer (assistant professor) at Bar Ilan University, Faculty of Engineering. I completed a Postdoc at Yale University in the applied math department, working with Prof. Ronald Coifman and Prof. Yuval Kluger. I completed my Ph.D. at the Department of Electrical Engineering at Tel Aviv University under the supervision of Prof. Arie Yeredor and Prof. Amir Averbuch.  My research is primarily focused on developing novel machine-learning methods for scientific discovery. My interest includes computational biology, signal processing, music, and audio analysis, manifold learning, spectral methods for data mining, and dimensionality reduction. I am interested in theory and practice of the following challenges:

  • Unsupervised learning- extracting latent parameters from high dimensional or multi-modal data.
  • Interpretability- exploiting sparsity to learn robust interpretable models that lead to the identification of predictive variables.
  • Generative Models- synthesizing reliable artificial data to enhance the prevalence of rare sub-population in biological/dynamical processes.
