Light Gradient Boosted Machine (LightGBM) is an efficient open-source implementation of the stochastic gradient boosting ensemble algorithm. How to develop LightGBM ensembles for classification and regression with the scikit-learn API. How to explore the effect of LightGBM model hyperparameters on model...
The novelty of the study is that classification of deep-hybrid features with the Light Gradient Boosted Machine model is evaluated as an event when the web address is entered on the address bar of the browser. Thus, phishing can be detected at every request entry before the process is ...
We train a gradient-boosted machine with fit parameters from 6061 ZTF SNe that pass data quality cuts and are spectroscopically classified as one of five classes: SN Ia, SN II, SN Ib/c, SN IIn, and SLSN-I. Without redshift information, our classifier yields a class-averaged F _1 -...

When a 0-2π linear phase profile is mapped in this super-cell, the energy channels into a single diffraction order (+1 or −1, depending on the sign of the slope of the gradient), resulting in beam steering. We first show in Fig. 4(a) that, when the device is unbiased, all ...
With the rapid advancement of artificial intelligence and automation technology, interest in autonomous driving research is also growing. However, under heavy rain, fog, and other adverse weather conditions, the visual quality of the images is reduced due to suspended atmospheric particles that affect ...
Colour-sensitive conjugated polymer inkjet-printed pixelated artificial retina model studied via a bio-hybrid photovoltaic device Article Open access 08 December 2020 Spectrum projection with a bandgap-gradient perovskite cell for colour perception Article Open access 15 September 2020 Introduction...
41. Such nanomaterials generate significant luminescence emission only at the spatial gradient maximum, that is from a region smaller than the size of the focal excitation light intensity pattern itself, resulting in enhanced resolution. This approach works without the need of inhibition light and ...
respectively. Optimizing the reaction conditions by increasing C2H4and CO pressure to 10 bar and 0.5 bar significantly boosted the productivity and liquid-phase selectivity of EG to 400.0 µmol·g−1and 60.5%, respectively. Note that the addition of CO suppressed the formation of C2H6and...
(e.g., decision trees, random forests, and gradient boosted trees), linear regression model(s) or logistic regression model(s), support vector machine(s) (“SVM”), artificial intelligence device(s), or any other type of intelligent computing system. Any amount of training data may be ...
