Relative Variational Intrinsic Control

open access: yesProceedings of the AAAI Conference on Artificial Intelligence, 2021
In the absence of external rewards, agents can still learn useful behaviors by identifying and mastering a set of diverse skills within their environment. Existing skill learning methods use mutual information objectives to incentivize each skill to be diverse and distinguishable from the rest.

Variational Intrinsic Control

open access: yesCoRR, 2016
In this paper we introduce a new unsupervised reinforcement learning method for discovering the set of intrinsic options available to an agent. This set is learned by maximizing the number of different states an agent can reliably reach, as measured by the mutual information between the set of options and option termination states.

Monitoring Reliability for Three-Parameter Frechet Distribution Using Control Charts

open access: yesIEEE Access, 2020
Control Charts for attributes have been widely adopted for examining the fraction non-conforming or non-conformities in a process. However, Shewhart control charts may face some practical problems when the process fraction of non-conformities is very low.

Reliability analysis of helium pressure non-destructive testing method of the fuel rod

open access: yesHe jishu, 2023
BackgroundCurrently, the destructive puncture manometry method is used to measure helium pressure inside fuel rods. However, this method is expensive and does not guarantee 100% coverage.

Efficient Attention via Control Variates

open access: yes, 2023
Random-feature-based attention (RFA) is an efficient approximation of softmax attention with linear runtime and space complexity. However, the approximation gap between RFA and conventional softmax attention is not well studied.

Truncated control variates for weak approximation schemes*

open access: yesESAIM: Proceedings and Surveys, 2017
In this paper we present an enhancement of the regression-based variance reduction approaches recently proposed in Belomestny et al. [1] and [4]. This enhancement is based on a truncation of the control variate and allows for a significant reduction of ...

Risk factors for suicidal tendency in people with epilepsy in China: a case–control study

open access: yesScientific Reports, 2021
People with epilepsy (PWE) have an increased suicide prevalence. This study aimed to identify the risk factors for suicidal tendency among PWE in West China. A nested case–control study was designed in a cohort of patients with epilepsy (n = 2087).

Control Variates as Screening Functions [PDF]

open access: yesProceedings of the 3rd International Conference on Performance Evaluation Methodologies and Tools, 2008
Suppose that the mean μ = E[F(X)] of a given function F: ℝ → ℝ is to be estimated by the empirical average Sn: = 1/nΣi=1n F(Xi) of the values F(Xi), where X1,X2, ..., Xn are independent samples distributed like X. In cases when the mean v = E[U(X)] of a different function U: ℝ → ℝ is known, we introduce a sampling rule, called the "screened estimator,"

Evaluasi non-destruktif pada pemalsuan tepung kacang merah (Phaseolus vulgaris L.) menggunakan spektroskopi visible-near infrared (VIS-NIR)

open access: yesAgrointek, 2023
Food adulteration is one of the biggest concerns of quality control. Food adulteration is adding or replacing a product with one or more similar products to increase economic value.

On the optimal control for variational inequalities [PDF]

open access: yesJournal of Optimization Theory and Applications, 1976
We prove an existence theorem for the optimal control of variational inequalities governed by a pseudomonotone operator: the cost is assumed to be quadratic. Then, we give an extension of the theorem to more general costs (assuming the operator to be monotone); we also give a result on a perturbation problem.
