Hi, I have not used reuters-21578 my k-means.
These steps I followed. I have prepared sequence directory then seq2sparse directory. ./mahout kmeans -Dmapred.map.java.child.opts=-Xmx1g -i /urlcat-data/56-categories/vector-dir/tfidf-vectors/ \ -c /urlcat-data/56-categories/cluster-centroids -o /urlcat-data/56-categories/kmeans-cluster-output \ -ow -dm org.apache.mahout.common.distance.CosineDistanceMeasure -x 5 -ow -cd 1 -k 49 --clustering -cl mahout clusterdump -i /opt/49-classification/cluster-centroids -o /opt/49-classification/kmeans-cluster-output/clusteranalyze1.txt -p /opt/49-classification/kmeans-cluster-output/clusteredPoints/ -d /root/Desktop/final_feature_dictionaries.txt -dt text -e; I have checked examples/bin/cluster-reuters.sh and downloaded reuters-21578 Can you please let me know what should I do now.
