Feature CAM: Interpretable AI in Image Classification

no code implementations8 Mar 2024 Frincy Clement, Ji Yang, Irene Cheng

We then extend the same for eight CNN-based architectures to compare the differences in visualization and thus interpretability.

Dive into Layers: Neural Network Capacity Bounding using Algebraic Geometry

1 code implementation3 Sep 2021 Ji Yang, Lu Sang, Daniel Cremers

To mathematically prove this, we borrow a tool in topological algebra: Betti numbers to measure the topological geometric complexity of input data and the neural network.

Molecular Clouds in the Second Quadrant of the Milky Way Mid-plane from l$=$104$.\!\!^{\circ}$75 to l=119$.\!\!^{\circ}$75 and b=$-$5$.\!\!^{\circ}$25 to b=5$.\!\!^{\circ}$25

About 78\% of the N-PDFs of the selected molecular clouds are well fitted with log-normal functions with only small deviations at high-densities which correspond to star-forming regions with scales of $\sim$1-5 pc in the Local arm and $\sim$5-10 pc in the Perseus arm.

Distances to molecular clouds in the second Galactic quadrant

no code implementations17 Dec 2020 Qing-Zeng Yan, Ji Yang, Yan Sun, Yang Su, Ye Xu, Hongchi Wang, Xin Zhou, Chen Wang

We present distances to 76 medium-sized molecular clouds and an extra large-scale one in the second Galactic quadrant ($104. 75^\circ <l<150. 25^\circ $ and $|b|<5. 25^\circ$), 73 of which are accurately measured for the first time.

Cuid: A new study of perceived image quality and its subjective assessment

no code implementations28 Sep 2020 Lucie Lévêque, Ji Yang, Xiaohan Yang, Pengfei Guo, Kenneth Dasalla, Leida Li, Yingying Wu, Hantao Liu

It is thus critical to acquire reliable subjective data with controlled perception experiments that faithfully reflect human behavioural responses to distortions in visual signals.

Geodesic Distance Function Learning via Heat Flow on Vector Fields

no code implementations1 May 2014 Binbin Lin, Ji Yang, Xiaofei He, Jieping Ye

Based on our theoretical analysis, we propose to first learn the gradient field of the distance function and then learn the distance function itself.
