If we select four 2D Gaussian kernels, we can run iteratively the EM mixture-modeling algorithm to estimate the 4-clusters and finally classify the points ...

One way to view a Gaussian distribution in two dimensions is what's called a contour plot. The coloring represents the region's intensity, or how high it ...

I only have x-data, so to get according y-data I make my histogram and #use the bins as x-data and the numbers (hist) as y-data.

In general, there is no guarantee that structure found by a clustering algorithm has anything to do with what we were interested in.

but it isn't good enough if you compare it to my expected outcome. With least square I get a "good fit"

But that was in one dimension, what about two, three, four . . . It turns out the univariate (one-dimensional) Gaussian can be extended to the multivariate ...

We use it to assign unique file names to the input file for each structure in the molecule group, and then save all of them in a single operation.

Escrevi um codigo bem util para ajuste de duas gaussianas em um conjunto de dados XY em Python. Como não achei nada parecido na internet (que não esteja ...

The red curve is just an exponential, which I added some gaussian noise to to make the blue curve. The teal curve is the blue curved smoothed with a ...

That also means that we can calculate the probability of a point being under a Gaussian 'bell', i.e. the probability of a point belonging to a cluster.

It turns out that the GMM cannot capture the truncation well and tries to fit the complete Gaussian model within the gridded space.

I need to plot the resulting gaussian obtained from the score_samples method onto the histogram. I have tried following the code in the answer to ...

Intro to Expectation-Maximization, K-Means, Gaussian Mixture Models with Python, Sklearn — BLACKARBS LLC

K-means is very efficient for easy clustering. It assumes fixed-K and that separation based on distance from centroids is a match for data patterns.

Visualization of EM Initialize the mean and standard deviation of each Gaussian randomly. Repeat until

From the plot of different iterations in the EM algorithms, one can see that the Gaussian model is incrementally updated and refined to fit the data and the ...
