    • 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 predicFons 
    • 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}
    • Step 2: Train Create a new model by training on data To train a model:POST prediction/v1.1/training?data=mybucket%2FmydataTraining runs asynchronously. To see if it has finished:GET prediction/v1.1/training/mybucket%2Fmydata{"data":{ "data":"mybucket/mydata", "modelinfo":"estimated accuracy: 0.xx"}}}
    • Step 3: Predict  Apply the trained model to make predicFons on new data POST prediction/v1.1/query/mybucket%2Fmydata/predict{ "data":{ "input": { "text" : [ "Jaime X! Cest le meilleur" ]}}}
    • Step 3: Predict Apply the trained model to make predicFons on new data POST prediction/v1.1/query/mybucket%2Fmydata/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}]}}
    • Step 3: Predict Apply the trained model to make predicFons on new data An example using Python import httplibheader = {"Content-Type" : "application/json"}#...put new data in JSON format in params variableconn = httplib.HTTPConnection("www.googleapis.com")conn.request("POST", "/prediction/v1.1/query/mybucket%2Fmydata/predict”, params, header)print conn.getresponse()
    • Prediction API CapabilitiesData•  Input Features: numeric or unstructured text•  Output: up to hundreds of discrete categoriesTraining•  Many machine learning techniques•  Automatically selected•  Performed asynchronouslyAccess from many platforms:•  Web app from Google App Engine•  Apps Script (e.g. from Google Spreadsheet)•  Desktop app
    • Prediction API v1.1 - features•  Updated Syntax•  Multi-category prediction o  Tag entry with multiple labels•  Continuous Output o  Finer grained prediction rankings based on multiple labels•  Mixed Inputs o  Both numeric and text inputs are now supportedCan combine continuous output with mixed inputs
    • Prediction API Demos•  Creating training data – recipes.csv•  Simple REST access •  Training the prediction engine •  Start predicting!•  A Java Web example
    • Google BigQueryInteractive analysis of large datasets in Googles cloud
    • Introducing Google BigQuery•  Googles large data adhoc analysis technology o  Analyze massive amounts of data in seconds•  Simple SQL-like query language•  Flexible access o  REST APIs, JSON-RPC, Google Apps Script
    • Why BigQuery?  Working with large data is a challenge 
    • Many Use Cases ...  InteracFve Tools  Trends  Spam DetecFon  Web Dashboards  Network  OpFmizaFon 
    • Key CapabiliFes of BigQuery  •  Scalable: Billions of rows •  Fast: Response in seconds •  Simple: Queries in SQL •  Web Service o  REST o  JSON-RPC o  Google App Scripts
    • Using BigQueryAnother simple three step process...  Upload your raw data to  1. Upload  Google Storage   Import raw data into BigQuery table  2. Import  3. Query  Perform SQL queries on table 
    • Writing QueriesCompact subset of SQL o  SELECT ... FROM ... WHERE ... GROUP BY ... ORDER BY ... LIMIT ...;Common functions o  Math, String, Time, ...Statistical approximations o  TOP o  COUNT DISTINCT
    • BigQuery via RESTGET /bigquery/v1/tables/{table name}GET /bigquery/v1/query?q={query}Sample JSON Reply:{ "results": { "fields": { [ {"id":"COUNT(*)","type":"uint64"}, ... ] }, "rows": [ {"f":[{"v":"2949"}, ...]}, {"f":[{"v":"5387"}, ...]}, ... ] }}Also supports JSON-RPC
    • Security and PrivacyStandard Google Authentication•  Client Login•  OAuth•  AuthSubHTTPS support•  protects your credentials•  protects your dataRelies on Google Storage to manage access
