Intelligent apps are emerging as the next frontier in analytics and application development. Learn how to build intelligent apps on MongoDB powered by Google Cloud with TensorFlow for machine learning and DialogFlow for artificial intelligence. Get your developers and data scientists to finally work together to build applications that understand your customer, automate their tasks, and provide knowledge and decision support.

“In 2018, 75% of AI projects will underwhelm because they fail to model operational
considerations, causing business leaders to reset the scope of AI investments.”

18. Training Recommendation Model
1. install the model code
2. place data into your Cloud Storage Bucket
3. run training script
When the training is finished, the model data is saved in a subdirectory named model under
the job directory of the training task. This data consists of several arrays, all saved in numpy
format
./mltrain.sh train
gs://recserve_jfmlrecengine/swag_pageviews.cs
v --data-type web_views

19. Tuning Recommendation Model
Hyperparameter tuning optimizes your machine learning model for most accuracy
Typically data scientists experimenting with various values, test the model, and then pick a combination
of parameters with the best performance.
But you can test every possible combination of parameters…. it would take a very very long time
● Each hyperparameter is passed to
the hyperparameter tuning job on
Cloud ML Engine.
● The model writes a TensorFlow
summary with a special tag that's set
to the metric that evaluates the
quality of the model.
● This summary metric enables the
search process of the Cloud ML
Engine hyperparameter tuning
./mltrain.sh tune
gs://recserve_jfmlrecengine/
swag_pageviews.csv --data-
type web_views

20. AI does AI
Systematic exploration
of the model space, using
the techniques finessed in
AlphaGo, yields super-human
performance in AI network design

21. Generate Recommendations
model.py : generate_recommendations
input
user: row index of the user in the rating matrix
items: list of indexes for items that the user has rated / viewed
latent factors: row and column factors generated by training / tuning the
model
number of desired recommendations

22. Serving Recommendations with Stitch
MongoDB Stitch send a HTTP GET
request to Google Cloud Endpoint
to obtain recommendations
For user who is logged in
Get list of product
recommendations
Update user profile with that
list
Service Integrations make it
simple for your app to use
leading third party services
Functions: build complex logic and orchestrate data
between clients, and services
Stitch scales precisely to meet your usage.
