是的，她說她要過去求阿貝索貝斯家務必到拍賣的現場來，並且買下這座房子，因為她認定，彼得大伯寧願由他們家而不是別的人家把這座房子買下來。她準備纏著他們不放，直到他們答應會來。如果能說通，並且她還沒有累倒，她就會回家來。Comparing with non - bnyain methods, it ' s prominent featares lay in that it combines the prior and posterior information, which avoids the disadvantag of subjective bias caused by simply using the prior information only, of blind search caused by the incomplete sample information, of noise affection caused by simply using the sample information only if we choice a suitable priof, we can conduct the bayesian leaming effectively, so it fits the problems of data mining and machine leaming that possess charaters of probability and statistics, especially when the samples are rare
與非貝葉揚方法相比，貝葉斯方法的特出特點是其學習機制可以綜合先驗信息和后驗信息，既可避免只使用先驗信息可能帶來的主觀偏見，和缺乏樣本信息時的大量盲目搜索與計算，也可避免只使用樣本信息帶來的噪音的影響只要合理地確定先驗，就可以進行有效的學習。因此，適用於具有概率統計特徵的數據採掘和機器學習（或發現）問題，尤其是樣本難得的問題The nobel prize in literature : wole soyinka
諾貝爾文學獎-沃萊索因卡Classification has always been a central issue on data mining, machine learning and pattern recognition, classifier, as an important model and method of machine learning and data mining, is very important to the development and application of machine learning and the data mining. the classifier ’ s effect closely correlates with the characteristic of data sets, at present, the construction of classifier is generally based on the character of different datasets, there is no such a classifier which is suitable for any data sets. under uncertain conditions, the bayes network is a powerful tools for the knowledge expression and inference, but for difficulties in constructing its network structure and very high time complexity, it has not been considered as a classifier algorithm until the emergence of na ? ve - bayes classifier
分類一直是數據挖掘、機器學習和模式識別等研究的核心問題，貝葉斯網路是作為知識表示和推理的強大工具，由於搜索空間巨大和學習困難的原因，直到樸素貝葉斯理論的出現才被作為分類器演算法，改進樸素貝葉斯分類器是貝葉斯分類器學習的一個主要的研究方向。遺傳演算法本質上是一種求解問題的高效并行全局搜索演算法，適合應用於那些改進的分類器的結構學習中。本文提出了一種基於遺傳演算法的ban分類器演算法。Boro captain gareth southgate has passed a fitness test but franck queudrue only makes the bench so 18 year - old matthew bates fills the gap in the visitors ' back three
米堡隊長加樂斯-索斯蓋特已經傷愈但弗蘭克-奎杜坐壁上觀，因此18歲的馬休-貝茨臨時替補客隊后衛三人組合。( 3 ) the inhere drawback of traditional algorithms to construct bayesian networks is pointed out. so the local bayesian network metric attribute based - on bayesian dirichlet metric is also researched, and some notions on bayesian networks are presented, such as comparability, independency and symmetry on nodes etc. it is showed that the comparability is an important factor on whether two nodes is linked, and a sufficient condition for nodes with most comparability is obtained. by using this analysis on local bayesian network, the important principia are presented to create graph models
（ 3 ）由於構造貝葉斯網路圖的傳統演算法存在固有缺陷，本文通過探索貝葉斯網路圖的內在規律，主要研究基於bd度量的局部貝葉斯網路圖的度量屬性，提出網路圖中節點的相似性、獨立性及對稱性等新概念，得出相似性是兩節點連接與否非常重要的因素，對稱節點具有相同的bd度量值，獲得具有最強獨立性節點的充分條件。She admits she would struggle with the workload and says she is lucky to have a very supportive husband in jonathan steinberg, son of financier saul steinberg, a former magazine publisher who is now launching a family of exchange traded funds
