Study of Manifold Geometry Using Multiscale Non-Negative Kernel Graphs

ICASSP 2023accepted

Modern machine learning systems are increasingly trained on large amounts of data embedded in high-dimensional spaces. Often this is done without analyzing the structure of the dataset. In this work, we propose a framework to study the geometric structure of the data. We make use of our recently int…

Channel Redundancy and Overlap in Convolutional Neural Networks with Channel-Wise NNK Graphs

ICASSP 2022accepted

Feature spaces in the deep layers of convolutional neural networks (CNNs) are often very high-dimensional and difficult to inter-pret. However, convolutional layers consist of multiple channels that are activated by different types of inputs, which suggests that more insights may be gained by studyi…

Collaborative voting of 3D features for robust gesture estimation

ICASSP 2017accepted

Human body analysis raises special interest because it enables a wide range of interactive applications. In this paper we present a gesture estimator that discriminates body poses in depth images. A novel collaborative method is proposed to learn 3D features of the human body and, later, to estimate…
