Title:  “Cognitive-assisted Interactive Labeling & Software 2.0 “

Future cognitive systems will largely make use of self-optimizing cognitive models, called Software 2.0, where the primary remaining task will be to provide labels/supervision. Software 2.0 will provide fully learned programs even for complex objectives and program functions, just requiring the human to specify the desired behavior. Human involvement in machine learning is thus evolving from engineering features, to hyperparameter optimization, and finally to providing supervision. In this talk we propose the use of machine learning itself in the Toolchain for Software 2.0, where the objective is to efficiently obtain and manage supervision. We modify a versatile SGD-based dimensionality reduction algorithm to allow for feature space quality assessment and for direct editing of the feature space itself, with labels as final output for use in image classifier training. We show the improvements in labeling efficiency through cognitive assistance for a variety of benchmark datasets.

Bio:  Francois Luus is a Research Scientist at the Johannesburg lab of IBM Research | Africa where machine learning is advanced and applied in the domains of healthcare, environment and finance. He holds a PhD in Computer Engineering and his research interests include computer vision, deep learning and dimensionality reduction, which led to innovations in Earth Observation during his time at the Council for Scientific and Industrial Research. Previously he conducted information-theoretic coding research at the Sentech Broadband Wireless Multimedia Center aimed at improving the robustness of wireless communications.
