In this study, statistical downscaling of general circulation model (GCM) simulations to monthly inflows of Kemer Dam in Turkey under A1B, A2, and B1 emission scenarios has been performed using machine learning methods, multi-model ensemble and bias correction approaches. ...
We show that (the spectra alone allows good discrimination of the samples based on rheology, (3D-PCA allows comprehensive and informative visualization of the data, and (that the rheological parameters are predicted accurately using a regression method such as PLSR; instead of using chemical ...

Goal:PCA aims to find a new set of orthogonal variables that capture the maximum amount of variance in the data, while SVD aims to find a decomposition of a matrix into singular values and associated singular vectors. Use of the Data:PCA is an unsupervised learning technique that can be us...
Let’s understand the main methods of using machine learning in SEO and how they are used today. 1. Support Vector Machines Classification is a process that significantly facilitates segmentation. In other words, support-vector machines (SVM) are a set of prediction algorithms that classify custo...
