    • A grid-based data clustering method performed by a computer system includes a setup step, a dividing step, a categorizing step and an expanding/clustering step. The setup step sets a grid quantity and a threshold value. The dividing step divides a space containing a data set having a plurality of data points into a two-dimensional matrix. The matrix has a plurality of grids G(i,j) comprising a plurality of target sequences and a plurality of non-target sequences interlaced with the plurality of target sequences. The indices “i” and “j” of each grid G(i,j) represents the coordinate thereof. The categorizing step determines whether each of the grids is valid based on the threshold value. The expanding/clustering step respectively retrieves each of the grids of the target sequences, performs an expansion operation on each of the grids retrieved and clusters the plurality grids G(i,j).
    • 由计算机系统执行的基于网格的数据聚类方法包括设置步骤,分割步骤,分类步骤和扩展/聚类步骤。 设置步骤设置网格数量和阈值。 分割步骤将包含具有多个数据点的数据集的空间划分成二维矩阵。 矩阵具有包含与多个目标序列隔行的多个目标序列和多个非目标序列的多个网格G(i,j)。 每个网格G(i,j)的索引“i”和“j”表示其坐标。 分类步骤基于阈值确定每个网格是否有效。 扩展/聚集步骤分别检索目标序列的每个网格,对所检索的每个网格执行扩展操作,并聚集多个网格G(i,j)。
