Strategies for hierarchical clustering generally fall into two types:<\/p>\n<ul>\n<li><strong>Agglomerative<\/strong> : This is a &#8220;bottom up&#8221; approach: each observation starts in its own cluster, and pairs of clusters are merged as one moves up the hierarchy.<\/li>\n<li><strong>Divisive<\/strong> : This is a &#8220;top down&#8221; approach: all observations start in one cluster, and splits are performed recursively as one moves down the hierarchy.<\/li>\n<\/ul>\n<p>Hierarchical clustering is often used for exploratory data analysis, as it can provide a useful way to visualize the relationships between data points. However, it is important to note that hierarchical clustering does not provide a unique solution: different algorithms can produce different hierarchies, and the choice of which algorithm to use can have a significant impact on the results.<\/p>\n<p>In addition, hierarchical clustering is not always robust to noise in the data. If there are outliers or other errors in the data, they can have a disproportionate impact on the results of the clustering.<\/p>\n<p>Overall, hierarchical clustering is a powerful tool for exploratory data analysis, but it is important to be aware of its limitations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;TRUE&#8221;
