Signal Processing at the Epicenter of Ground-Shaking Research: Researchers turn to signal processing to minimize earthquake damage, rescue victims, and perhaps even provide advance warnings

Earthquakes have afflicted people throughout history. Today, thanks to advanced technology, more is known about earthquakes, and more can be done to protect people against them. Signal processing is playing a key role as investigators examine ways to combat one of humanity’s most deadly foes.

Starting the Ethics Discussion in Our Community

IEEE members are bound by the IEEE Code of Ethics [1] . By becoming IEEE members, we commit ourselves to the highest ethical and professional conduct. We agree to uphold the practices of ethical design and sustainable development; protect the privacy of others; and promptly disclose factors that might endanger the public or the environment. We strive to improve the public understanding of the implications of technology.

Scientific Integrity: A Duty for Researchers

Ethics in science is essential for various reasons and is a duty for scientists. The full sense of the word ethics may differ according to languages and countries. For instance, in France, we typically make a distinction between ethics and scientific integrity, while scientific integrity is a part of ethics in the United States.

Memories From a Historic, Hybrid, Distributed ICASSP

This past May marked the beginning of our return to face-to-face events after almost three years of pandemic-forced virtual-only interactions. The first attempt was the 2022 ICASSP! Planning for large international events in the era of postpandemic uncertainty is not an easy undertaking. Of course, signal processing is all about dealing with uncertainty—and who would be better at planning than IEEE Signal Processing Society (SPS) people?

A Trick for Designing Composite Filters With Sharp Transition Bands and Highly Suppressed Stopbands

Designing a perfect filter (i.e., flat passband, sharp transition band, and highly suppressed stopband) is always the goal of digital signal processing practitioners. This goal is reachable if we make no consideration of implementation complexity. In other words, the challenge of designing a high-performance filter is to leverage the distortion tradeoff in the passband, transition band, and stopband.

Proper Definitions of Dirichlet Conditions and Convergence of Fourier Representations

Fourier theory is the backbone of signal processing (SP) and communication engineering. It has been widely used in almost all branches of science and engineering in numerous applications since its inception. However, Fourier representations such as Fourier series (FS) and Fourier transform (FT) may not exist for some signals that fail to fulfill a predefined set of Dirichlet conditions (DCs).

The Submerged Part of the AI-Ceberg

This article discusses the contradiction between the exploding energy demand of artificial intelligence (AI) and the information and communication (ICT) industry as a whole and the parallel strong request for energy sobriety imposed by the need to mitigate the impact of climate change and the anticipated collapse of civilization as we know it.

Toward Explainable Artificial Intelligence for Regression Models: A methodological perspective

In addition to the impressive predictive power of machine learning (ML) models, more recently, explanation methods have emerged that enable an interpretation of complex nonlinear learning models, such as deep neural networks. Gaining a better understanding is especially important, e.g., for safety-critical ML applications or medical diagnostics and so on. Although such explainable artificial intelligence (XAI) techniques have reached significant popularity for classifiers, thus far, little attention has been devoted to XAI for regression models (XAIR).
