On the left side of this V-shaped curve, tangent lines slope downward. On the right side, they slope upward. At the bottom vertex, the slope abruptly changes directions. The function’s derivative does ...

When analyzing data, one can use a variety of transformations on the data to massage it into a form that works better to tease out the information one is interested in. One such example is the appl… ...

Overview of Adversarial Frequency Attack and Training: A model trained on voxel-domain adversarial attacks is vulnerable to frequency-domain adversarial attacks. In our proposed adversarial training ...

Recent ideas for handling doppler in communications such as Orthogonal Time-Frequency Space (OTFS) modulation have explicitly connected to radar concepts through the auto-ambiguity function.

The fast Fourier Transform (FFT), added to an oscilloscope or digitizer, permits measuring the frequency domain spectrum of the acquired signals. This provides a different and usually helpful ...

Natural images consist mainly of low-frequency functions. Images of people transformed into the frequency domain: the upper left corner represents low-frequency image areas, the lower right corner ...
