Dr. James McCaffrey presents a complete end-to-end demonstration of linear regression with pseudo-inverse training implemented using JavaScript. Compared to other training techniques, such as ...

My soulmate fell in love with my roommate. It took me years to figure out what happened. The Social Security retirement age rises close to average life expectancy The latest: Former Trump aides appear ...

Abstract: Recently, the volume-gradient-based band selection (VGBS) method has attracted more and more attention in the field of band selection. It is a ranking-based unsupervised algorithm which ...

Calculate annual % change by dividing start by end value, raising to inverse years, minus one, times 100. Ex: a drop from $15M to $10M over 2 years is a 18.4% average annual decline. This calculation ...

In part 3 of this series, we used the inverse fast Fourier transform (IFFT) to create 100-Hz time-domain waveforms of various amplitudes and phases. We can also use the IFFT to create waveforms ...

The inverse transform can create a time-domain waveform where no waveform has been before. In part 2 of this series, we used the discrete Fourier transform to convert a waveform from the time domain ...

Amidst all the Apple Intelligence / AI, visionOS 2, macOS Sequoia, and iPhone AI announcements at WWDC 2024, one feature literally got a “yay” from Apple itself: the calculator app for iPad. In case ...

Photonic innovation: researchers in the US have created an optical metamaterial that can perform vector–matrix multiplication. (Courtesy: iStock/Henrik5000) A new silicon photonics platform that can ...

This file type includes high resolution graphics and schematics. You can build an analog calculator using a pulse-width modulator (PWM) to perform accurate four-quadrant multiplication and division.

Matrix inversion is an essential element in linear algebra and has numerous applications across science, engineering, and mathematics. The matrix inverse of a square matrix A is denoted as A⁻¹ and ...
