Google Prediction API Google's prediction engine in the cloud
![Page 44: Introduction to Google's Cloud Technologies](https://reader033.vdocuments.us/reader033/viewer/2022051110/54bf0b5c4a7959c5538b45c7/html5/thumbnails/44.jpg)
Introducing the Google Prediction API
• Google's sophisticated machine learning technology • Available as an on-demand RESTful HTTP web service
![Page 45: Introduction to Google's Cloud Technologies](https://reader033.vdocuments.us/reader033/viewer/2022051110/54bf0b5c4a7959c5538b45c7/html5/thumbnails/45.jpg)
How does it work?
"english" The quick brown fox jumped over the lazy dog.
"english" To err is human, but to really foul things up you need a computer.
"spanish" No hay mal que por bien no venga.
"spanish" La tercera es la vencida.
? To be or not to be, that is the quesIon.
? La fe mueve montañas.
The Prediction API finds relevant features in the sample data during training.
The PredicIon API later searches for those features during predicIon.

Using the Prediction API
1. Upload
2. Train
Upload your training data to Google Storage
Build a model from your data
Make new predicIons 3. Predict
A simple three step process...
![Page 48: Introduction to Google's Cloud Technologies](https://reader033.vdocuments.us/reader033/viewer/2022051110/54bf0b5c4a7959c5538b45c7/html5/thumbnails/48.jpg)
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}
![Page 49: Introduction to Google's Cloud Technologies](https://reader033.vdocuments.us/reader033/viewer/2022051110/54bf0b5c4a7959c5538b45c7/html5/thumbnails/49.jpg)
Step 2: Train Create a new model by training on data
To train a model:
POST prediction/v1.1/training?data=mybucket%2Fmydata Training runs asynchronously. To see if it has finished:
GET prediction/v1.1/training/mybucket%2Fmydata
{"data":{ "data":"mybucket/mydata", "modelinfo":"estimated accuracy: 0.xx"}}}
![Page 50: Introduction to Google's Cloud Technologies](https://reader033.vdocuments.us/reader033/viewer/2022051110/54bf0b5c4a7959c5538b45c7/html5/thumbnails/50.jpg)
Step 3: Predict Apply the trained model to make predicIons on new data
POST prediction/v1.1/query/mybucket%2Fmydata/predict { "data":{ "input": { "text" : [ "J'aime X! C'est le meilleur" ]}}}
![Page 51: Introduction to Google's Cloud Technologies](https://reader033.vdocuments.us/reader033/viewer/2022051110/54bf0b5c4a7959c5538b45c7/html5/thumbnails/51.jpg)
Step 3: Predict Apply the trained model to make predicIons on new data
POST prediction/v1.1/query/mybucket%2Fmydata/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}]}}

Step 3: Predict Apply the trained model to make predicIons 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/v1.1/query/mybucket%2Fmydata/predict”, params, header)
print conn.getresponse()

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
