Speech separation algorithm based on laplace normal mixture distribution probability density function estimation 基于拉普拉斯正態(tài)混合分布概率密度函數(shù)估計(jì)的語音分離算法
In this dissertation , life - testing with mixture distribution is discussed and problems are solved as follows : 1 本文對(duì)混合分布的壽命試驗(yàn)進(jìn)行了研究,主要解決了下面幾個(gè)問題: 1
However , when the life distribution is a mixture distribution , i . e . , there are many reasons cause the products to be failure , which problem has not been studied . but it is more useful in practice 而當(dāng)產(chǎn)品的壽命分布為一混合分布,即產(chǎn)品具有多個(gè)失效機(jī)理時(shí)的問題,由于其實(shí)用性而更具有研究的意義。
The vq - based approach assumes a gaussian mixture distribution , which fits real - world image data reasonably well . after estimating this distribution through em method , this approach trains optimized vector quantizers to partition data space 該方法使用更適合真實(shí)圖像庫的高斯混合模型描述數(shù)據(jù)分布,并訓(xùn)練優(yōu)化的矢量量化器劃分?jǐn)?shù)據(jù)空間。
This paper starts with the financial market micro - structure theory . it takes trading - volume as a vital factor in the process of the price adjustment , and quotes the mdh ( mixture distribution hypothesis ) to explain the price - volume relation 本文主要從金融市場(chǎng)微觀結(jié)構(gòu)理論出發(fā),把交易量作為影響價(jià)格調(diào)整過程的一個(gè)重要因素,引用混合分布假說( mdh )來解釋股票市場(chǎng)的量?jī)r(jià)關(guān)系。
Based on the mixture distribution hypothesis ( mdh ) theory , the paper conducted an empirical study into the daily liquidity and volatility of three futures , i . e . , bronze , aluminum and natural rubber , and discovered that the trade volume and volatility display a significantly positive correlation , there is a significantly negative correlation between the open interest and volatility , and liquidity ratio and volatility have no significant correlation 摘要根據(jù)混合分布假設(shè)理論( mdh )等前人研究成果,及對(duì)中國(guó)期貨市場(chǎng)三個(gè)主要期貨交易品種銅、鋁和天然膠期貨的日流動(dòng)性和日波動(dòng)性的實(shí)證研究,可以發(fā)現(xiàn):交易量與波動(dòng)率有顯著的正相關(guān)關(guān)系,持倉(cāng)量與波動(dòng)率有顯著的負(fù)相關(guān)關(guān)系;而流動(dòng)性比率與波動(dòng)性卻并沒有顯著的關(guān)系。
After reviewing some statistical models proposed to better characterize the host signal in dct , dwt and spatial domain , we describe the statistical property of host signal using gaussian scale mixture distribution , which is more general and flexible . we also present a new method for estimating the parameters of generalized gaussian distribution rapidly 研究了細(xì)節(jié)分量的統(tǒng)計(jì)模型,包括平穩(wěn)高斯模型、平穩(wěn)拉普拉斯模型、平穩(wěn)廣義高斯模型、局部平穩(wěn)的高斯模型和高斯尺度混合模型,提出了一種廣義高斯模型中形狀參數(shù)的快速估計(jì)方法。
百科解釋
In probability and statistics, a mixture distribution is the probability distribution of a random variable whose values can be interpreted as being derived in a simple way from an underlying set of other random variables. In particular, the final outcome value is selected at random from among the underlying values, with a certain probability of selection being associated with each.
