proper vector的用法和樣例：
例句
- First, a fixed-dimensional feature vector is generated for each protein sequence using the frequency of the hydropathy blocks occurring in the sequence.
首先，利用蛋白質序列中親水模塊的出現頻率，每條蛋白質序列被轉換為一個特徵向量。 - It outperforms much better than the other two in that it calculates and maximizes the feature vector distance between multi-modal clusters in a hyper-sphere space.
該方法能計算並最大化高維空間中的多模式聚集特徵向量距離，由於具有滿足三角不等式和非奇性的特性，相對於其他兩種方法，它提高了檢測性能。
