CMOS OTA-Based Filters for Designing Fractional-Order Chaotic Oscillators
Fractal and Fractional, 2021 Fractional-order chaotic oscillators (FOCOs) have shown more complexity than integer-order chaotic ones. However, the majority of electronic implementations were performed using embedded systems; compared to analog implementations, they require huge ...

Active Collaborative Filtering
CoRR, 2012 Collaborative filtering (CF) allows the preferences of multiple users to be pooled to make recommendations regarding unseen products. We consider in this paper the problem of online and interactive CF: given the current ratings associated with a user, what queries (new ratings) would most improve the quality of the recommendations made?
