I have seen this but not sure what it means

I think the issue was by ths following , I have been looking into some javascript code and noticed this not sure what it does and why you would use it , The above is the minified version of this:
let reset = function(a, b) {
  if (!b) {
    b = something;
    if (b.somethingelse) {
      b.other = b.somethingelse;
    }
  }
  //some other code underneath
}

does k-means clusterer of apache commons math contains a means method?


Tag : algorithm , By : wiznick

it should still fix some issue The output of the clustering algorithm must at least contain the cluster assignments, i.e. which cluster each point belongs to. If you have that, then the k-means clustering cluster centers are simply given by the mean of the points that belong to each cluster.

Boxplot overlaid on dot plot + means, means in wrong position

this one helps. The help for ?position_dodge just says that dodging things with different widths is tricky - I usually tweak this manually. Trying a few values, it looks like you want the points to take a dodge width that is 3/4 of the boxplot width but I don't know why or if that holds for other geoms. I would try changing the width for the stat_summary call to 0.15

Rolling means and applying means at beginning of a series of data

wish help you to fix your issue Use right aligment with partial=TRUE, i.e. rollapplyr(..., partial=TRUE) or rollapply(..., align = "right", partial=TRUE). Here we use rollapplyr:
rollapplyr(df$a, 4, mean, partial = TRUE)

I think the issue was by ths following , I have a df, df['period'] = (df['date1'] - df['date2']) / np.timedelta64(1, 'D') , pivot_table with margins=True
piv = df.pivot_table(
    index='code', columns='y_m', values='period', aggfunc='mean', margins=True
)
# housekeeping
(piv.reset_index()
    .rename_axis(None, 1)
    .rename({'code' : -1, 'All' : 0}, axis=1)
    .sort_index(axis=1)
)

  -1         0        201701   201702
0    1000  1.750000      1.5      2.0
1    2000  1.200000      1.5      1.0

Scikit Learn K-means Clustering & TfidfVectorizer: How to pass top n terms with highest tf-idf score to k-means


Tag : python , By : yew tree

this will help I am clustering the text data based on TFIDF vectorizer. The code works fine. It takes entire TFIDF vectorizer output as input to the K-Means clustering and generate a scatter plots. Instead I would like to send only top n-terms based on TF-IDF scores as input to the k-means clustering. Is there a way to achieve that ? , use max_features in TfidfVectorizer to consider the top n features
vect = TfidfVectorizer(ngram_range=(1,3),stop_words='english', max_features=n)
