LEARNING
• How do we learn?
• Try something (else) => get feedback => learn
• Eventually:
• We get it (understanding) so we can predict the outcome
of a certain action in a new situation
• Or we have experienced enough situations to predict
the outcome in most situations with high confidence
• Through interpolation, extrapolation, etc.
• We remain clueless
9
MACHINE LEARNING
• Analyze Historical Data (input and result – training set) to discover
Patterns & Models
• Iteratively apply Models to [additional] Input (test set) and compare
model outcome with known actual result to improve the model
• Use Model to predict
outcome for
entirely new data
10

TYPES OF MACHINE LEARNING
• Supervised
• Train and test model from known data (both features and target)
• Unsupervised
• Analyze unlabeled data – see if you can find anything
• Semi-Supervised
• Interactive flow, for example human identifying clusters
• Reinforcement
• Continuously improve algorithm (model) as time progresses, based on new
experience
MACHINE LEARNING ALGORITHMS
• Clustering
• Hierarchical k-means, Orthogonal Partitioning Clustering, Expectation-Maximization
• Feature Extraction/Attribute Importance/Principal Component Analysis
• Classification
• Decision Tree, Naïve Bayes, Random Forest, Logistic Regression, Support Vector Machine
• Regression
• Multiple Regression, Support Vector Machine, Linear Model, LASSO,
Random Forest, Ridgre Regression, Generalized Linear Model,
Stepwise Linear Regression
• Association & Collaborative Filtering
(market basket analysis, apriori)
• Reinforcement Learning – brute force, value function,
Monte Carlo, temporal difference, ..
• Neural network and Deep Learning with
Deep Neural Network
• Can be used for many different use cases
MODELING PHASE
• Select a model to try to create a fit with (predict target well)
• Set configuration parameters for model
• Divide data in training set and test set
• Train model with training set
• Evaluate performance of trained model on the test set
• Confusion matrix, mean square error, support, lift, false positives, false negatives
• Optionally: tweak model parameters, add attributes, feed in more training data,
choose different model
• Eventually (hopefully): pick model plus parameters plus attributes
that will reliably predict the target variable given new data
• Possibly combine multiple models to collaborate on target value

CLASSIFICATION GONE WRONG
• Machine learning applied to millions of drawings
on QuickDraw
• to classify drawings

MACHINE LEARNING  OPERATIONAL
SYSTEMS
• “We have a model that will choose best chess move based on
certain input”
MACHINE LEARNING  OPERATIONAL
SYSTEMS
• Discovery => Model => Deploy
• “We have a model that will predict a class (classification) or value
(regression) based on certain input with a meaningful degree of
accuracy” – how can we make use of that model?
DEPLOY MODEL AND EXPOSE
• Model is usually created on Big Data in Data Science environment using the
Data Scientist’s tools
• Model itself is typically fairly small
• Model will be applied in operational systems against single data items (not
huge collections nor the entire Big Data set)
• Running the model online may not require extensive resources
• Implementing the model at production run time
• Export model (from Data Scientist environment) and import (into production
environment)
• Reimplement the model in the development technology and deploy (in the regular
way) to the production environment
• Expose model through API
80M PICTURES OF ROAD
BIG DATA => SMALL ML MODELS
DEPLOY MODEL AND EXPOSE
REST
API
MODEL MANAGEMENT
• Governance (new versions, testing and approval)
• A/B testing
• Auditing (what did the model decide and why? notifying humans? )
• Evaluation (how well did the model’s output match the reality)
to help evolve the model
• for example recommendations followed
• Monitor self learning models (to detect rogue models)
WHAT TO DO IT WITH?
• Mathematics (Statistics)
• Gauss (normal distribution)
• Bayes’ Theorem
• Euclidean Distance
• Perceptron
• Mean Square Error

NOTEBOOK –
THE LAB JOURNAL FROM THE DATALAB
• Common format for data exploration and presentation
• User friendly interface on top of powerful technologies
• Most popular implementations
• Jupyter (fka IPython)
• Apache Zeppelin
• Spark Notebook
• Beaker
• SageMath (SageMathCloud => CoCalc)
• Oracle Machine Learning Notebook UI
• Try out Jupyter at: https://mybinder.org/
EXAMPLE NOTEBOOK EXPLORATION
OPEN DATA
• Governments and NGOs, scientific and even commercial
organizations are publishing data
• Inviting anyone who wants to join in to help make
sense of the data – understand driving factors,
identify categories, help predict
• Many areas
• Economy, health, public safety, sports, traffic &
transportation, games, environment, maps, …
OPEN DATA – SOME EXAMPLES
• Kaggle - Data Sets and [Samples of] Data Discovery: www.kaggle.com
• US, EU and UK Government Data: data.gov, open-data.europa.eu and data.gov.uk
• Open Images Data Set: www.image-net.org
• Open Data From World Bank: data.worldbank.org
• Historic Football Data: api.football-data.org
• New York City Open Data - opendata.cityofnewyork.us
• Airports, Airlines, Flight Routes: openflights.org
• Open Database – machine counterpart to Wikipedia: www.wikidata.org
• Google Audio Set (manually annotated audio events)
- research.google.com/audioset/
• Movielens - Movies, viewers and ratings:
files.grouplens.org/datasets/movielens/
WHAT IS HADOOP?
• Big Data means Big Computing and Big Storage
• Big requires scalable => horizontal scale out
• Moving data is very expensive (network, disk IO)
• Rather than move data to processor – move processing to data: distributed
processing
• Horizontal scale out => Hadoop:
distributed data & distributed processing
• HDFS – Hadoop Distributed File System
• Map Reduce – parallel, distributed processing
• Map-Reduce operates on data locally, then
persists and aggregates results
WHAT IS SPARK?
• Developing and orchestrating Map-Reduce on Hadoop is not simple
• Running jobs can be slow due to frequent disk writing
• Spark is for managing and orchestrating distributed processing on a
variety of cluster systems
• with Hadoop as the most obvious target
• through APIs in Java, Python, R, Scala
• Spark uses lazy operations and distributed in-memory data
structures – offering much better performance
• Through Spark – cluster based processing can be used interactively
• Spark has additional modules that leverage distributed
processing for running prepackaged jobs (SQL, Graph, ML, …)

  • 24. TYPES OF MACHINE LEARNING • Supervised • Train and test model from known data (both features and target) • Unsupervised • Analyze unlabeled data – see if you can find anything • Semi-Supervised • Interactive flow, for example human identifying clusters • Reinforcement • Continuously improve algorithm (model) as time progresses, based on new experience
  • 25. MACHINE LEARNING ALGORITHMS • Clustering • Hierarchical k-means, Orthogonal Partitioning Clustering, Expectation-Maximization • Feature Extraction/Attribute Importance/Principal Component Analysis • Classification • Decision Tree, Naïve Bayes, Random Forest, Logistic Regression, Support Vector Machine • Regression • Multiple Regression, Support Vector Machine, Linear Model, LASSO, Random Forest, Ridgre Regression, Generalized Linear Model, Stepwise Linear Regression • Association & Collaborative Filtering (market basket analysis, apriori) • Reinforcement Learning – brute force, value function, Monte Carlo, temporal difference, .. • Neural network and Deep Learning with Deep Neural Network • Can be used for many different use cases
  • 26. MODELING PHASE • Select a model to try to create a fit with (predict target well) • Set configuration parameters for model • Divide data in training set and test set • Train model with training set • Evaluate performance of trained model on the test set • Confusion matrix, mean square error, support, lift, false positives, false negatives • Optionally: tweak model parameters, add attributes, feed in more training data, choose different model • Eventually (hopefully): pick model plus parameters plus attributes that will reliably predict the target variable given new data • Possibly combine multiple models to collaborate on target value

  • 31. DEPLOY MODEL AND EXPOSE • Model is usually created on Big Data in Data Science environment using the Data Scientist’s tools • Model itself is typically fairly small • Model will be applied in operational systems against single data items (not huge collections nor the entire Big Data set) • Running the model online may not require extensive resources • Implementing the model at production run time • Export model (from Data Scientist environment) and import (into production environment) • Reimplement the model in the development technology and deploy (in the regular way) to the production environment • Expose model through API
  • 33. BIG DATA => SMALL ML MODELS
  • 34. DEPLOY MODEL AND EXPOSE REST API

  • 47. WHAT IS HADOOP? • Big Data means Big Computing and Big Storage • Big requires scalable => horizontal scale out • Moving data is very expensive (network, disk IO) • Rather than move data to processor – move processing to data: distributed processing • Horizontal scale out => Hadoop: distributed data & distributed processing • HDFS – Hadoop Distributed File System • Map Reduce – parallel, distributed processing • Map-Reduce operates on data locally, then persists and aggregates results
  • 48. WHAT IS SPARK? • Developing and orchestrating Map-Reduce on Hadoop is not simple • Running jobs can be slow due to frequent disk writing • Spark is for managing and orchestrating distributed processing on a variety of cluster systems • with Hadoop as the most obvious target • through APIs in Java, Python, R, Scala • Spark uses lazy operations and distributed in-memory data structures – offering much better performance • Through Spark – cluster based processing can be used interactively • Spark has additional modules that leverage distributed processing for running prepackaged jobs (SQL, Graph, ML, …)

Editor's Notes

  • #2: Our technology has gotten smart and fast enough to make predictions and come up with recommendations in near real time. Machine Learning is the art of deriving models from our Big Data collections – harvesting historic patterns and trends – and applying those models to new data in order to rapidly and adequately respond to that data. This presentation will explain and demonstrate in simple, straightforward terms and using easy to understand practical examples what Machine Learning really is and how it can be useful in our world of applications, integrations and databases. Hadoop and Spark, real time and streaming analytics, Watson and Cloud Datalab, Jupyter Notebooks, Oracle Machine Learning CS and the Citizen Data Scientists will all make their appearance, as will SQL.
