POGD: Gradient Descent with New Stochastic Rules
Feihu Han, Sida Xing, Sui Yang Khoo
There introduce Particle Optimized Gradient Descent (POGD), an algorithm based on the gradient descent but integrates the particle swarm optimization (PSO) principle to achieve the…
A six-octave optical frequency comb from a scalable few-cycle erbium fiber laser
Daniel M. B. Lesko, Henry Timmers, Sida Xing +3
A compact and robust coherent laser light source that provides spectral coverage from the ultraviolet to infrared is desirable for numerous applications, including heterodyne super…
Extreme-Long-short Term Memory for Time-series Prediction
Sida Xing, Feihu Han, Suiyang Khoo
The emergence of Long Short-Term Memory (LSTM) solves the problems of vanishing gradient and exploding gradient in traditional Recurrent Neural Networks (RNN). LSTM, as a new type…
Multi-watt 1 GHz single-cycle frequency combs
Yanyan Zhang, Sida Xing
Single-cycle optical pulses offer a strong carrier-envelope-offset (CEO) dependent electric field and the highest peak intensity for a given pulse energy. Absence of demonstrated G…
1-GHz mid-infrared frequency comb spanning 3 to 13 μm
Nazanin Hoghooghi, Sida Xing, Peter Chang +4
Mid-infrared (MIR) spectrometers are invaluable tools for molecular fingerprinting and hyper-spectral imaging. Among the available spectroscopic approaches, GHz MIR dual-comb absor…
Two-octave frequency combs from all-silica-fiber implementation
Yanyan Zhang, Mingkun Li, Pan Zhang +5
Mid-infrared frequency comb spectroscopy enables measurement of molecular at megahertz spectral resolution, sub-hertz frequency accuracy and microsecond acquisition speed. However,…
