  22. 22. Google Prediction APIGoogles prediction engine in the cloud
  23. 23. Google Prediction API as a simple example Predicts outcomes based on learned patterns
  24. 24. How does it work? "english" The quick brown fox jumped over theThe Prediction API lazy dog.finds relevant "english" To err is human, but to really foul thingsfeatures in the up you need a computer.sample data during "spanish" No hay mal que por bien no venga.training. "spanish" La tercera es la vencida.The Prediction APIlater searches for ? To be or not to be, that is the question.those features ? La fe mueve montañas.during prediction.
  25. 25. A virtually endless number of applications... Customer Transaction Species Message Diagnostics Sentiment Risk Identification Routing Churn Legal Docket Suspicious Work Roster InappropriatePrediction Classification Activity Assignment ContentRecommend Political Uplift Email Career Products Bias Marketing Filtering Counselling ... and many more ...
  26. 26. Using the Prediction APIA simple three step process... Upload your training data to 1. Upload Google Storage Build a model from your data 2. Train 3. Predict Make new predictions
  27. 27. Step 1: Upload Upload your training data to Google Storage● Training data: outputs and input features● Data format: comma separated value format (CSV) "english","To err is human, but to really ..." "spanish","No hay mal que por bien no venga." ... Upload to Google Storage gsutil cp ${data} gs://yourbucket/${data}
  28. 28. Step 2: TrainCreate a new model by training on dataTo train a model:POST prediction/v1.3/training{"id":"mybucket/mydata"}Training runs asynchronously. To see if it has finished:GET prediction/v1.3/training/mybucket%2Fmydata{"kind": "prediction#training",...,"training status": "DONE"}
  29. 29. Step 3: Predict Apply the trained model to make predictions on new dataPOSTprediction/v1.3/training/mybucket%2Fmydata/predict{ "data":{ "input": { "text" : [ "Jaime X! Cest le meilleur" ]}}}
  30. 30. Step 3: Predict Apply the trained model to make predictions on new dataPOST prediction/v1.3/training/bucket%2Fdata/predict{ "data":{ "input": { "text" : [ "Jaime X! Cest le meilleur" ]}}}{ data : { "kind" : "prediction#output", "outputLabel":"French", "outputMulti" :[ {"label":"French", "score": x.xx} {"label":"English", "score": x.xx} {"label":"Spanish", "score": x.xx}]}}
  31. 31. Step 3: Predict Apply the trained model to make predictions on new dataimport httplibheader = {"Content-Type" : "application/json"}#...put new data in JSONformat in params variableconn = httplib.HTTPConnection("www.googleapis.com")conn.request("POST", "/prediction/v1.3/query/bucket%2Fdata/predict", params, header)printconn.getresponse()
