Motivation<\/h3>\n\n

Conventional sensing systems acquire data in a fixed way, independent of the task the data will actually serve, and the acquisition, reconstruction, and inference stages of the processing pipeline are designed and optimized separately. The result is an ever-growing volume of measurements and an unsustainable demand for power, storage, processing, and communication.<\/p>\n\n

Approach<\/h3>\n\n

This project develops an adaptive, task-oriented and physics-aware data-to-decision pipeline that jointly optimizes what is measured, how it is reconstructed, and how decisions are made \u2014 all within a single learning framework. Work is organized along three connected directions:<\/p>\n\n

    \n
  • Physics-aware learned reconstruction<\/strong> \u2014 network architectures derived from regularized inverse problems and classical signal processing models, so that what the network does remains interpretable.<\/li>\n\n
  • Task-oriented measurement design<\/strong> \u2014 learning constrained, hardware-realizable measurement operators jointly with the reconstruction and inference blocks that follow them.<\/li>\n\n
  • Direct inference from few measurements<\/strong> \u2014 classification and parameter estimation performed straight from a small number of learned measurements, without a full reconstruction step.<\/li>\n<\/ul>\n\n
    \"Learning<\/figure>\n\n
