Sharp Power Mean Bounds for Sándor Mean [PDF]
, 2015 We prove that the double inequality Mp(a,b)0 with a≠b if and only if p≤1/3 and q≥log 2/(1+log 2)=0.4093…, where X(a,b) and Mr(a,b) are the Sándor and rth power means of a and b ...

Interactive Self-Training with Mean Teachers for Semi-supervised Object Detection
Computer Vision and Pattern Recognition, 2021 The goal of semi-supervised object detection is to learn a detection model using only a few labeled data and large amounts of unlabeled data, thereby reducing the cost of data labeling.

Mean-shift outlier detection and filtering
Pattern Recognition, 2021 Traditional outlier detection methods create a model for data and then label as outliers for objects that deviate significantly from this model. However, when dat has many outliers, outliers also pollute the model.

On a class of new means including the generalized Schwab-Borchardt mean [PDF]
, 2017 The so-called Schwab-Borchardt mean plays an important role in the theory of (bivariate) means. It includes a lot of standard means, such as the logarithmic mean, the first and second Seiffert means and the Neuman-Sándor mean.

Root-mean-square error (RMSE) or mean absolute error (MAE): when to use them or not
Geoscientific Model Development, 2022 . The root-mean-squared error (RMSE) and mean absolute error (MAE) are widely used metrics for evaluating models. Yet, there remains enduring confusion over their use, such that a standard practice is to present both, leaving it to the reader to decide ...

Sharp bounds involving the Sandor-Yang means in terms of other bivariate means
Advances in Inequalities and Applications, 2019 In this paper, we present the best possible parameters ${\alpha _1},{\alpha _2},{\alpha _3},{\alpha _4},{\beta _1},{\beta _2},{\beta _3},{\beta _4} \in [0,1]$ such that the double inequalities hold for all $a,b > 0$ with $a \neq b$.

Receiver Multiuser Diversity Aided Multi-Stage MMSE Multiuser Detection for DS-CDMA and SDMA Systems Employing I-Q Modulation [PDF]
, 2010 The so-called receiver multiuser diversity aided multistage minimum mean-square error multiuser detector (RMD/MS-MMSE MUD), which was proposed previously by the author, is investigated in the context of the direct-sequence code-division multiple-access ...

Sharp bounds for Sándor-Yang means in terms of quadratic mean
, 2018 In the article, we find the best possible parameters α , β , λ , μ ∈ (1/2,1) such that the double inequalities Q[αa+(1−α)b,αb+(1−α)a] < RQA(a,b) < Q[βa+(1−β)b,βb+(1−β)a], Q[λa+(1−λ)b,λb+(1−λ)a] < RAQ(a,b) < Q[μa+(1−μ)b,μb+(1−μ)a] hold for all a,b > 0 ...

Sharp bounds for Sandor-Yang means in terms of Lehmer means
, 2017 In the article, the authors prove that the double inequalities $L_{0} (a,b) 0$ with $a\ne b$, where $L_{p} (a,b)=\left( {a^{p+1}+b^{p+1}}\right)/\left( {a^{p}+b^{p}} \right)$ is the $p$th Lehmer mean, and $S_{AQ} (a,b)$, $S_{QA} (a,b)$ are the S\'{a}ndor-
