WebSamples that have similar expression profiles in a dataset are located closely together on the 2D or 3D map, which enables the user to find clusters of similar samples.One such clustering method that is popular in biomedical research is the so called t-SNE algorithm. t-SNE stands for t-Distributed Stochastic Neighbor Embedding. WebOct 1, 2024 · This work was done using both R, and Python. The clustering part was done using R and the packages caret, and cluster. ... On one hand, a low k, for example, k=2, means that all the observations of the dataset will be clustered into 2 clusters, resulting in a large amount of error, and a most likely hard-to-interpret clustering result.
