Machine Learning in Elixir: Scholar.Clustering.KMeans.fit/2 is undefined (B1.0, Chapter 5, Page 109)
Hey @seanmor5,
On page 109:
model = Scholar.Clustering.KMeans.fit(train_inputs, num_clusters: 3)
results in an UndefinedFunctionError.
I believe it should be
model = Scholar.Cluster.KMeans.fit(train_inputs, num_clusters: 3)
-
Clusterinstead ofClustering
Also, there’s a typo on the first paragraph after the Using Clustering header.
Perhaps the most common type of unsupervised leraning is clustering
- learning is mispelled
