Abnormal event detection in crowded scenes using sparse representation
Published 2013“…To condense the over-completed normal bases into a compact dictionary, a novel dictionary selection method with group sparsity constraint is designed, which can be solved by standard convex optimization. Observing that the group sparsity also implies a low rank structure, we reformulate the problem using matrix decomposition, which can handle large scale training samples by reducing the memory requirement at each iteration from O(k2) to O(k) where k is the number of samples. …”

Strong electro-optically active Ni-substituted Pb(Zr0.35Ti0.65)O3 thin films : toward integrated active and durable photonic devices
Published 2020“…In addition, optical measurements indicate a large refractive index (∼2.43), a low propagation loss (∼4.14 dB cm−1), a fast response time (4.02 μs), and an effective EO coefficient (167.7 pm V−1), which are five times larger than those of the current standard material for EO devices (LiNbO3). More importantly, such films can work well up to 250 °C and retain above 80% of the EO performance at 104 Hz. …”

Simplified architecture of a fully printable perovskite solar cell using a thick zirconia layer
Published 2020“…After systematic optimization of these processes, we found that the double‐printing of the c‐TiO2 layer and an increase of the ZrO2 later thickness from 1.4 to 2.1 μm in the device structure gives an optimized efficiency of 9.69 %, which is comparable to that of standard carbon devices with meso‐TiO2. This method provides an approach to reduce the fabrication time and thermal budget for fully printable solar cells.…”

Bootstrapping the performance of webly supervised semantic segmentation
Published 2020“…Our method is formulated as a two-stage approach in which we first aim to create accurate pixel-level masks for the training images via a bootstrapping process, and then use these now-accurately segmented images as a proxy ground-truth in a more standard supervised setting. The key driver for our work is that in the target dataset we typically have reliable ground-truth image-level labels, while data crawled from the web may have unreliable labels, but can be filtered to comprise only easy images to segment, therefore having reliable boundaries. …”
