Area and circularity act as two elements of the eigenvector for they can remarkably characterize the surface area of the bubbles.

We also find that among the three investment strategies we discussed – the momentum strategy, buying the top or the bottom decile portfolio of funds, adopting the momentum strategy gets a better Sharpe ratio if the emerging market, energy, and mineral funds are not considered. For the portfolio of emerging market, energy, and mineral funds, it is with better performance for the strategies of buying the top or the bottom decile portfolio of funds.

最后，以Sharpe ratio为比较各投资策略在各投资分类的基准，采取动能策略操作基金，在移除新兴、能源、矿业基金之投资组合中有较高的报酬；又以买入形成期表现最好及买入形成期表现最差的基金为操作策略时，在新兴、能源、矿业基金这一分类出现较佳之绩效。

The larger the weight of an attribute was, the more it would make the contribution to classification. on the contrary, it would reduce the effect of classification. the new classification algorithm and the cloud classifier were applied to classify the radiance profiles as cumulonimbus, cirrus clouds, or cirrostratus clouds.

采用云模型建立训练集的各属性模型，分类模型由属性模型集成得到，属性权重根据svm权重向量得到，属性权重越大，其对分类的贡献越大；反之，越小。
