Design of an AIC CMOS vision system for spatio-temporal event detection (ESR2)


Machine learning and, in particular deep learning techniques constitute a unique framework for analog to information (AIC) compression. Nevertheless, the feasibility of a hardware implementation of such power and memory-hungry algorithms calls for new strategies that benefit from the low power features of analog and mixed-signal design techniques. The final goal of this work will be the design of a low Size, Weight and Power (SWaP) AIC CMOS vision system for spatio-temporal event detection through deep learning tracking techniques. The system will comprise a CMOS vision chip with focal-plane processing and a general-purpose embedded hardware such as an FPGA. The CMOS vision chip will acquire the video and provide the detections that trigger the tracking. The baseline of our tracking approach will be state-of-the-art neural networks that learn similarity functions. Compressive deep learning techniques like binary weighting, weight sharing and pruning will be required to fit such networks on the FPGA.

The successful candidate will be employed for a maximum period of three years full-time equivalent and receives a generous financial package plus an additional mobility and family allowance according to the rules for Early Stage Researchers (ESRs) in an EU Marie Sklodowska-Curie Actions Innovative Training Networks (ITN). A career development plan will be prepared for each fellow in accordance with his/her supervisor and will include training, planned secondments and outreach activities in partner institutions of the network. The ESR fellows are supposed to complete their PhD thesis by the end of the 3rd year of their employment.

Supervisor: Prof. Dr. Paula López Martínez

Planned Recruitment date: 1st September 2020.
Eligibility Criteria and Mobility Rule

ESRs must, at the date of recruitment, be in the first four years (full-time equivalent research experience) of their research careers and have not been awarded a doctoral degree. Full-Time Equivalent Research Experience is measured from the date when the researcher obtained the first degree entitling him/her to embark on a doctorate (either in the country in which the degree was obtained or in the country in which the researcher is recruited), even if a doctorate was never started or envisaged. Researchers can be of any nationality.

ESRs must not have resided or carried out their main activity (work, studies, etc.) in the country of the recruiting beneficiary for more than 12 months in the 3 years immediately before the planned recruitment date. Compulsory national service, short stays such as holidays, and time spent as part of a procedure for obtaining refugee status under the Geneva Convention are not taken into account.
