Our results are indicative of weak or semi-strong market efficiency. Introduction Bitcoin is the first widely-used cryptocurrency (Bloomberg). It was devised as a ‘purely peer-to-peer electronic cash system without the need for a central authority to prevent double-spending or to issue new ...
TheEfficient Market Hypothesis (EMH)Model has three versions – Strong, semi-strong, and weak. The weak form of market efficiency is the weakest form of this Hypothesis model.According to the EMH theory, the price of a publicly-traded asset or security is a reflection of all the past inform...
Market efficiency of the bitcoin exchange rate: Weak and semi-strong form tests with the spot, futures and forward foreign exchange rates 来自 EconPapers 喜欢 0 阅读量: 39 作者:Z Nan,T Kaizoji 摘要: We propose a bitcoin-based exchange rate of USD/EUR and investigate market efficiency in ...

will fluctuate within a region in other time periods. It is only in some point of time in some important information will affect the price of it. According to statistics, its effectiveness, so it belongs to between weak and semi- strong. 如所示,它的数据在其他时期内经过一段时间常去波动,在...
fixmatch是google提出的一个semi supervised分类算法,提出采用简单的strong-weak augmentation范式即可在半监督上取得sota的结果。 strong-weak augmentation是指利用model在weak augmented的image上取得伪标签,并利用这个伪标签监督模型在strong augmented image的训练。
We propose a projected semi-stochastic gradient descent method with mini-batch for improving both the theoretical complexity and practical performance of the general stochastic gradient descent method (SGD). We are able to prove linear convergence under weak strong convexity assumption. This requires no...
Semi-supervised Semantic Segmentation via Strong-weak Dual-branch Network论文笔记 Wprofessor 西安电子科技大学IPIU2 人赞同了该文章 摘要 虽然现有的研究已经探索了各种技术来推动弱监督语义切分的范围,但与监督方法相比,仍有很大的差距。在实际应用中,除了大量的弱监督数据外,通常还存在少量可用的像素级标注,基于这...
Thesemi-strong formefficiency theory follows the belief that because all information that is public is used in the calculation of a stock'scurrent price, investors cannot utilize either technical or fundamental analysis to gain higher returns in the market. Those who...
