21. Google Prediction API
Google's prediction engine in the cloud

22. Google Prediction API as a simple example
Predicts outcomes based on 'learned' patterns

23. How does it work?

during prediction.

24. A virtually endless number of applications...
Customer Transaction Species Message Diagnostics
Sentiment Risk Identification Routing
Churn Legal Docket Suspicious Work Roster Inappropriate
Prediction Classification Activity Assignment Content
Recommend Political Uplift Email Career
Products Bias Marketing Filtering Counselling
... and many more ...

25. Using the Prediction API
A 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

26. 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}

27. Step 2: Train
Create a new model by training on data
To 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"}

28. Step 3: Predict
Apply the trained model to make predictions on new data
POST
prediction/v1.3/training/mybucket%2Fmydata/predict
{ "data":{
"input": { "text" : [
"J'aime X! C'est le meilleur" ]}}}

29. Step 3: Predict
Apply the trained model to make predictions on new data
POST prediction/v1.3/training/bucket%2Fdata/predict
{ "data":{
"input": { "text" : [
"J'aime X! C'est le meilleur" ]}}}
{ data : {
"kind" : "prediction#output",
"outputLabel":"French",
"outputMulti" :[
{"label":"French", "score": x.xx}
{"label":"English", "score": x.xx}
{"label":"Spanish", "score": x.xx}]}}

30. Step 3: Predict
Apply the trained model to make predictions on new data
import httplib
header = {"Content-Type" : "application/json"}#...put new data in JSON
format in params variable
conn = httplib.HTTPConnection("www.googleapis.com")conn.request
("POST",
"/prediction/v1.3/query/bucket%2Fdata/predict", params, header)print
conn.getresponse()

31. Demo

○ Google App Scripts

39. Using BigQuery
Another simple three step process...
Upload your raw data to
1. Upload Google Storage
Import raw data into
2. Import
BigQuery table
3. Query Perform SQL queries on
table

40. Writing Queries
Compact subset of SQL
○ SELECT ... FROM ...
WHERE ...
GROUP BY ... ORDER BY ...
LIMIT ...;
Common functions
○ Math, String, Time, ...
Statistical approximations
○ TOP
○ COUNT DISTINCT

41. BigQuery via REST
GET /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

42. Security and Privacy
Standard Google Authentication
● Client Login
● OAuth
● AuthSub
HTTPS support
● protects your credentials
● protects your data
Relies on Google Storage to manage access

43. Large Data Analysis Example
