Integrate everything together nicely and move from prototyping to production?

• collect data
• train your algorithm
• build a layer to serve the prediction results
• manage the different algorithms
• evaluations
• deploy your application in production

PredictionIO

• PredictionIO is a machine learning server for building and deploying predictive engines on production in a fraction of the time
• Built on Apache Spark, MLlib and HBase.

1. Open-source Machine Learning server.
2. Core - engine deployment platform built on top of Apache Spark.
3. Event Server built on top of Apache HBase.
4. DASE architecture of engine is the "MVC for Machine Learning".
5. Swap and evaluate algorithms as you wish.
6. Zero downtime training and deployment.
7. Engine template.

$ pio template get
$ cd MyEngine
$ pio build; pio train; pio deploy

Start with an Engine Template

Data Source                - readTraining()
Data Preparator            - prepare()
Algorithm:                 - train() 
                           - predict()
Serving                    - serve()
Evaluator                  - evaluate()

Customize Code with Software Design Pattern

• DASE - the "MVC" for Machine Learning
• Built-in support to Spark MLlib, or create your own algorithm

cli = predictionio.EventClient("<my_app_id>")
cli.record_user_action_on_item("view","John","HackerNews")
# predict top preferences
eng = predictionio.EngineClient("<my_engine_url>")
rec = eng.send_query({"uid":"John","n":5})</my_engine_url></my_app_id>

Connect to your App with SDKs

Respond to Prediction Query - The DASE View

Query (Input) :

$ curl -H "Content-Type: application/json" -d
'{ "user": "1", "num": 4 }'
http://localhost:8000/queries.json

Predicted Result (Output):

{“itemScores”:[{"item":"22","score":4.072304374729956},
{"item":"62","score":4.058482414005789},
{"item":"75","score":4.046063009943821}]}
