We calculated the Shannon entropy as a measure of uncertainty in the predictions of the machine learning models using the following formula, where H is entropy, X is a discrete random variable with possible probabilities (p) ranging from p1to pn, and i is an index variable: ...
value for each frame was calculated using the imagehash library. the hash value calculation formula is given by: h = phash( i ), where i represents the input image. by calculating the hamming distance d between the hash values of adjacent frames, we quantify the visual changes as d...

version R7.1.2. These notes are arranged by topic. Understand that in many cases, a particular note may have applicability to multiple topics, but in the interest of brevity, each note is listed only under one topic heading.
Chinese claim to have a secret formula guaranteeing 120yr life for the HK-Macao bridge. I regret I won’t be around to see the result.SpaceLifeForm • October 9, 2022 11:19 PM @ lurker, JonKnowNothing, ALL When concrete is formed, ask yourself, where does the water go? Hint: ...
matrix. Following the phase inversion, the rubber domains cease to increase and maintain their boundaries as the polymerization in both phases continues [64,70]. The mass polymerization of HIPS is predominantly done in a continuous process. There are various processes described in the patent ...
Extreme Gradient Boosting algorithm from the R packagexgboost,is one of the newly added features, to provide alternative option for implementing boosting model. The main effort in integrating xgboost into Rattle lies in three aspects: Define generic functions to provide a formula interface to streamlin...
