H2O Distributed Computing
• Multi-node cluster with shared memory model
• All computations in memory
• Each node sees only some rows of the data
• No limit on cluster size
• Distributed data frames (collection of vectors)
• Columns are distributed (across nodes) arrays
• Works just like R’s data.frame or Python Pandas

Reading data pandas.read_csv(data_path) h2o.import_file(data_path)
Summarizing data pandas_frame.describe() h2o_frame.describe()
Summary
statistics
pandas_frame.mean() h2o_frame.mean()
Combining rows pandas.concat(list[frame1,frame2]) h2o_frame.rbind(h2o_frame2)
Combining
columns
pandas.concat(list[frame1,frame2],axis = 1) h2o_frame.cbind(h2o_frame2)
Data selection pandas_frame[:, :] h2o_frame[:, :]
Transforming
columns
np.log(pandas_frame[x])
np.sqrt(pandas_frame[x])
h2o_frame[x].log()
h2o_frame[x].sqrt()
Building Random
Forest
model = RandomForestClassifier(n_estimators = 100)
model = model.fit(x_frame, y_frame)
model = H2ORandomForestClassifier(n_trees = 100)
model = model.train(x, y, train_frame)
Model Prediction model.predict model.predict
Model Metrics metrics.auc metrics = model.model_performance(frame)
metrics.auc()
