The spike shapes of the three primary neurons of the Antis Parabolis may be plotted using the spike width and amplitude. Which clustering method would best separate the spikes belonging to the three neurons?

Is it possible that the assignment of observations to clusters does not change between successive iterations in K-Means?

Which of the following clustering algorithms suffers from the problem of convergence at local optima?

1. K- Means clustering algorithm

2. Agglomerative clustering algorithm

3. Expectation-Maximization clustering algorithm

What could be the possible reason(s) for producing two different dendrograms using an agglomerative clustering algorithm for the same dataset?

An experiment records the concentration of 20 different molecules in the blood of 1000 volunteers. The hypothesis is that the volunteers may be divided into groups depending on the results of the recording. The concentration of each molecule is distributed in an approximately normal manner. What steps should be performed to divide the groups?
