So I have a data in the form [UID obj1 obj2..] x timestamp and I want to cluster this data in python using kmeans from sklearn. Where should I start?

EDIT:

So basically I'm trying to cluster users based on clickstream data, and classify them based on usage patterns.

    Could you give an example of what you are trying to achieve? – Neil Feb 09 '16 at 06:46

  • sci-kit has great implementations of [k-means](http://scikit-learn.org/stable/modules/generated/sklearn.cluster.KMeans.html#sklearn.cluster.KMeans) and other clustering algorithms – America Feb 17 '16 at 17:02

You can add more features based on the raw data, and using methods like RFM Analysis. RFM = recency, frequency, monetary

For example:

How often the user logged in?

The last time the user logged in?

You can use Python library Retentioneering (github), which allows you to cluster your users based on clickstream data with a simple command. You can also specify any target events you are interested in your clusters and explore obtained graphs using interactive graphs.

data.rete.get_clusters(method='kmeans',
                   feature_type='tfidf',
                   n_clusters=8,
                   ngram_range=(1,2),
                   plot_type='cluster_bar',
                   targets=['payment_done','cart']);

results of user clustering

Next you can explore obtained behavioral clusters with interactive graph:

clus_0 = data.rete.filter_cluster(0)
clus_0.rete.plot_graph(thresh=0.1,
                   weight_col='user_id',
                   targets = {'lost':'red',
                              'payment_done':'green'})
