The existing quantile regression methodology works well in the case of a fixed quantile level, or in the case of a quantile that is only moderately high, that is, τn→1 and n(1−τn)→∞ as n→∞, meaning that there are sufficient observations above the τn level. For more ...
However, prior results fall short of delineating clear dependencies of convergence rates on salient parameters such as the cardinality of the state space {\mathcal {S}} and the effective horizon \frac{1}{1-\gamma }, both of which could be excessively large. In this paper, we deliver a ...
Kirill Eremenko joins Jon Krohn for another exclusive, in-depth teaser for a new course just released on the SuperDataScience platform, “Machine Learning Level 2”. Kirill walks listeners through why decision trees and random forests are fruitful for bu
Meaning we need to try different values to see which ones yield the best prediction (on the training dataset, at least). Using the number of epochs as an example, I’ve created a loop to sequentially try 4, 5, 6… 100 epochs and for each epoch setting I’ve saved the RMSE value ob...
I think you're confused in the meaning of the "upside down" triangle. The upside down triangle is the del operator. http://en.wikipedia.org/wiki/Del It is invoked in the definition of grad (and div and curl). I think you are thinking that the upside down triangle is grad? Jul 26...
Traditional models have grappled with the unpredictability inherent in traffic incidents, often failing to capture the multifaceted influences on incident durations. This study introduces an application of Explainable Artificial Intelligence (XAI) using eXtreme Gradient Boosting (XGBoost) and SHapley Additive...
In the domain of dimension reduction, feature selection and feature transformation are different approaches. Feature selection refers to techniques that select a subset of the dimensions and discard the rest. This retains semantic meaning within the chosen data while avoiding the loss of information fro...
Because of recent progress in understanding the way in which chemotherapy affects cancer cells, new insights and more precise mathematical formulation of control problem, in the meaning of finding optimal chemotherapy, became possible. This, together with a progress in mathematical tools, has renewed ...
I can shoot the code over for rendering say a radial gradient and you guys can optimize it. Meaning we can have it so that it only renders an 1/8th of the data and you can transform that around to make the entire gradient. I don't know how to go about doing that last bit in LV...
