- 26. 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
- 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. 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"}
