A classical problem in data analysis is how to compress the size of data without destroying its salient information. This is becoming increasingly important in the era of big data where we need to process ever increasing quantities of data of various modalities. Some exciting new developments in this regard have recently emerged exploiting ideas such as kernel representations  and ‘sketching’  in new "compressive learning" algorithms [1, 2, 3].
This project will develop and analyse new algorithms for compressive learning and investigate their computational and statistical efficiency in processing big data. The studentship forms a key component of the advanced ERC project C-SENSE, "Exploiting Low Dimensional Models in Sensing, Computation and Processing".
The successful candidate will be located in the Prof Davies’ research group in the Institute for Digital Communications (IDCOM). There will also be opportunities to collaborate with the University of Edinburgh’s School of Mathematics and the Alan Turing Institute for Data Science.
