 ### Graph
 
+#### floatsam_sparsification
+
+Function using an iterative algorithm to try and find the best weight
+threshold to apply to trim the given graph's edges while keeping the
+underlying community structures.
+
+It works by iteratively increasing the threshold and stopping as soon as
+a significant connected component starts to drift away from the principal
+one.
+
+This is basically a very naive gradient descent with a very naive cost
+function but it works decently for typical cases.
+
+*Arguments*
+* **graph** *nx.Graph*: Graph to sparsify.
+* **starting_treshold** *float*: Starting similarity threshold.
+* **learning_rate** *?float* [`0.05`]: How much to increase the threshold
+at each step of the algorithm.
+* **max_drifter_size** *?int*: Max size of component to detach itself
+from the principal one before stopping the algorithm. If not
+provided it will default to the logarithm of the graph's total
+number of nodes.
+* **weight** *?str* [`weight wrt networkx conventions`]: Name of the weight attribute.
+* **remove_edges** *?bool* [`False`]: Whether to remove edges from the graph
+having a weight less than found threshold or not. Note that if
+`True`, this will mutate the given graph.
