- 8. © 2017 MapR TechnologiesMapR Confidential 8 What Most ML Tools Give You A common rule of thumb is that the modeling task is about 10% of the total effort of a ML project. The choice of tool matters (to the DS), but any top level ML tool/library can eventually get good results (if the data allows it at all)

- 10. © 2017 MapR TechnologiesMapR Confidential 10 Business Value is in Production All the business value results from a sufficiently accurate model running in production What it means: Deploying a weaker model in production sooner is MUCH better than endless work for an excellent model (But you can make Google money if you get a world class model in production)

- 20. © 2017 MapR TechnologiesMapR Confidential 20 • NFS mount and POSIX file system – Small scale Python or R data exploration on the real data – Keep the raw data, ETL work is easily reused • Supports standard big data ecosystem (Spark) • NFS mount can ingest data from any enterprise system that can output files – Even if they don’t support Hadoop! • Much faster than HDFS – Serve production models directly from MapR MapR Supports All Tools Out of the Box
- 21. © 2017 MapR TechnologiesMapR Confidential 21 • Volumes and Topologies – GPU enabled nodes for distributed deep learning on the same cluster • Don’t waste resources • Keep data locality • Avoid unnecessary data movement • Avoid multiple copies of data (which is the real one?) • POSIX file system – Use any DL framework on the cluster data MapR has production experience with CaffeOnSpark (Samsung Micro-Electronics) and has a new TensorFlow QSS MapR Supports Deep Learning
- 22. © 2017 MapR TechnologiesMapR Confidential 22 • Volumes and Snapshots – Experimental reproducibility – Create models on real production data – Easy to compare models on the same data – Easy to evaluate a model across time on different snapshots – snapshot of models: a time machine, built-in • Volume Quotas – Support multiple projects and teams on the same cluster – Share storage resources efficiently Clever Uses for Volumes and Snapshots
- 23. © 2017 MapR TechnologiesMapR Confidential 23 Remember that > 90% of the work in Enterprise ML is to realize the workflow. This is where MapR shines! • Operational capabilities (MapR DB, MapR Client) – Serve production models directly from MapR • Snapshots and Mirrors – Do A/B testing with almost no coding – Promote the mirror to go back to the previous state • Just update the path in the production system - no redeployment! • MapR Streams for Real-time predictions – Zero configuration Kafka – it just works! – Kafka REST Proxy for max interoperability – Supports microservices and Stateful Containers Support the ML Workflow, Not Just Modeling

Notes de l'éditeur
- 1. Will this tire fail in the next 1,000 miles: Yes or no? Which brings in more customers: a $5 coupon or a 25% discount? 2. If you have a car with pressure gauges, you might want to know: Is this pressure gauge reading normal? If you're monitoring the internet you’d want to know: Is this message from the internet typical? 3. What will the temperature be next Tuesday? What will my fourth quarter sales be? 4. Which viewers like the same types of movies? Which printer models fail the same way? 5. Reinforcement learning was inspired by how the brains of rats and humans respond to punishment and rewards. These algorithms learn from outcomes, and decide on the next action. Typically, reinforcement learning is a good fit for automated systems that have to make lots of small decisions without human guidance. 6. What did similar people/customer buy/watch/listen to? What other movies will you like, if you like product A?

- Get training data (example: images) Get labels for the training data (examples: what the image is about, the image labels) Transform the data into numbers (machine learning algorithms can’t deal with raw data, only vectors of numbers) Heavily iterative work to find the best set of features Try many different algorithms, and tune their parameters for best performance Heavily iterative work to find the best algorithm and parameter values The best algorithm, trained on your data, with its parameters tuned for best performance is your predictive model Get new data Transform it to match the same format as your training feature vectors The model will output a predicted label for the new data This is a lot of work, but glosses over a HUGE amount of work required to get business value in an enterprise setting
- Here is a small sample of the issues faced in putting ML to work in an enterprise
- This is for real. Chris Fregly is the Pipeline.io guy and he’s building enterprise ML systems with this set of tools. This is the set of tools required to be able to provide a true 100% open source end to end story for enterprise ML. How does MapR simplify this picture? What tools still remain useful if we’d run on MapR?
- Can support OSS tools like R, scikit, Theano and TensorFlow first to avoid more expensive licences. NoSQL, Kafka, Spark, etc...
- Indeed, ML Tools are only really good at modeling. They typically provide limited support for feature engineering. In addition Tools typically only support testing models on a single dataset, with no support for comparing production models to experimental models, comparing models across different versions of a dataset, etc. Such capabilities need to be custom made and are typically done with low quality ad-hoc code by data scientists. Most of the work resides in the ETL to get the data in the first place, the data cleaning and feature engineering not supported by the tools, as well as as the work required to deploy a model to production. MapR really shines on that 90% of the work, and supports all ML tools just the same (indeed, better) as any competing platform.
