Four different types of machine learning algorithms are available that can be organized into a taxonomy based on the desired outcome of the algorithm or the type of input available for training the machine. We can use machine learning:

Supervised Learning

  • Most machine learning is supervised learning.
  • Supervised learning algorithms are “trained” using labeled examples where the desired output is known.
  • It is called supervised learning because the process of an algorithm learning from the training dataset can be thought of as a teacher supervising the learning process
  • We know the correct answers, the algorithm iteratively makes predictions on the training data and is corrected by the teacher.
  • Learning stops when the algorithm achieves an acceptable level of performance.
  • Supervised learning is where you have input variables (x) and an output variable (Y) and you use an algorithm to learn the mapping function from the input to the output.
  • The goal is to approximate the mapping function so well that when you have new input data (x) that you can predict the output variables (Y) for that data.
  • Supervised learning problems can be further grouped into regression and classification problems.
    • Classification: A classification problem is when the output variable is a category, such as “red” or “blue” or “disease” and “no disease”.
    • Regression: A regression problem is when the output variable is a real value, such as “dollars” or “weight”.

We can:

  • Determine the input feature representation of the learned function.
    • The accuracy of the learned function depends strongly on how the input object is represented. Typically, the input object is transformed into a feature vector, which contains a number of features that are descriptive of the object. The number of features should not be too large, because of the curse of dimensionality; but should contain enough information to accurately predict the output.
  • Determine the structure of the learned function and corresponding learning algorithm
  • Complete the design
  • Run the learning algorithm
    • Some supervised learning algorithms require the user to determine certain control parameters. These parameters may be adjusted by optimizing performance on a subset (called a validation set) of the training set, or via cross-validation.
  • Evaluate the accuracy of the learned function

Image result for supervised learning, image

Unsupervised Learning

  • About 10 to 20 percent of machine learning is unsupervised learning.
  • Unsupervised learning is a type of machine learning where the system operates on unlabeled examples. In this case, the system is not told the “right answer.”
  • The algorithm tries to find a hidden structure or manifold in unlabeled data.
  • Unsupervised learning is where you only have input data (X) and no corresponding output variables.
  • The goal of unsupervised learning is to model the underlying structure or distribution in the data in order to learn more about the data.
  • These are called unsupervised learning because unlike supervised learning above there is no correct answers and there is no teacher. Algorithms are left to their own devices to discover and present the interesting structure in the data.
  • Unsupervised learning problems can be further grouped into clustering and association problems.
    • Clustering: A clustering problem is where you want to discover the inherent groupings in the data, such as grouping customers by purchasing behavior.
    • Association:  An association rule learning problem is where you want to discover rules that describe large portions of your data, such as people that buy X also tend to buy Y.

Image result for unsupervised learning, image

Semisupervised Learning

  • Problems where you have a large amount of input data (X) and only some of the data is labeled (Y) are called semi-supervised learning problems.
  • These problems sit in between both supervised and unsupervised learning.
  • Methods
    •  Generative models
      • Generative approaches to statistical learning first seek to estimate {\displaystyle p(x|y)}, the distribution of data points belonging to each class.
      • Generative models assume that the distributions take some particular form {\displaystyle p(x|y,\theta )} parameterized by the vector {\displaystyle \theta }. If these assumptions are incorrect, the unlabeled data may actually decrease the accuracy of the solution relative to what would have been obtained from labeled data alone.  However, if the assumptions are correct, then the unlabeled data necessarily improve performance.
    • Low-density separation
      • It attempts to place boundaries in regions where there are few data points (labeled or unlabeled). One of the most commonly used algorithms is the transductive support vector machine, or TSVM (which, despite its name, may be used for inductive learning as well).
    • Graph-based methods
      • Graph-based methods for semi-supervised learning use a graph representation of the data
    • Heuristic approaches
      • It is not intrinsically geared to learning from both unlabeled and labeled data, but instead, makes use of unlabeled data within a supervised learning framework.

Reinforcement Learning

AMSTAT Consulting uses reinforcement learning to discover for itself which actions yield the greatest rewards through trial and error. Reinforcement learning has three primary components:

  • The agent – the learner or decision maker
  • The environment – everything the agent interacts with
  • Actions – what the agent can do

Algorithms for reinforcement learning include:

  • Criterion of optimality
    • Policy
      • The agent’s action selection is modeled as a map called policy
      • The policy map gives the probability of taking action “a” when in state “s.”
    • State-value function
  • Brute Force
    •  The brute force approach entails two steps:
      •  For each possible policy, sample returns while following it.
      • Choose the policy with the largest expected return
  • Value Function
    • Value function approaches attempt to find a policy that maximizes the return by maintaining a set of estimates of expected returns for some policy (usually either the “current” [on-policy] or the optimal [off-policy] one).
    • These methods rely on the theory of MDPs, where optimality is defined in a sense that is stronger than the above one: A policy is called optimal if it achieves the best-expected return from an initial state (i.e., initial distributions play no role in this definition). Again, an optimal policy can always be found amongst stationary policies.

Generalization, Evaluation and Model Selection

We can:

  • Use all types of machine learning that develop models that enable the learning machine to perform accurately on new, unseen examples or tasks
  • Improve these models by using the machine
  • Want the fit to be not too much, not too little, but just right
  • Look at data of any complexity and size and build a model that sizes well to that data
  • Look at all the data or a subset to create an accurate model
    • One of the more powerful machine learning algorithms is a random forest.  A random forest takes individual decision trees and combines them. When a new input is entered into the system, it runs down all of the trees. The result is either an average or a weighted average of all the terminal nodes that are reached.
  • Validate a model to determine whether it can make effective predictions
  • Use a training data set to develop the model
  • Use known out-of-sample data to test it

Data Analytics

Today, the vast majority of enterprises have needs for descriptive analytics, which are necessary for effective management, but not sufficient to accelerate business performance. In order to scale to a higher level of responsiveness, enterprise organizations need to move beyond descriptive analytics and climb up the intelligence capability pyramid. We can use machine learning to help you with:

  • Descriptive Analytics
  • Diagnostic Analytics
  • Predictive Analytics
    • Predictive Modeling
    • Automated Modeling
    • Geospatial Analysis
    • Text Analytics
    • Social Network Analysis
    • Entity Analytics
  • Prescriptive Analytics
  • Cognitive Analytics
  • Operational Analytics
    • Supply Chain Analytics
    • Complexity Management
    • End-to-End Optimization
    • Supply Chain Risk Management
    • Advanced Supplier Management

ML (Machine Learning) is at the heart of Data Science. It powers predictive technology. We can apply it to serve the following business objectives:

  • Reduce user/customer attrition with churn prediction
  • Acquire new customers through lead scoring and marketing campaigns optimization
  • Cross-sell products with targeted campaigns and personalized recommendations
  • Optimize products and pricing by finding patterns in commerce data
  • Increase customer engagement by predicting their needs and interests
  • Improve operations by predicting demand (or improve resource management by predicting usage)
  • Save time by automating tasks
  • Make your team more productive, with predictive enterprise apps

We emphasize the use of machine learning to create predictive models:

  • Customer Satisfaction Prediction
  • Drug Selection for Treating Heart Problems
  • Predicting Financial Performance of a Company
  • Forecast Profits for Clothing Sales

We can:

  • Drive data scientist productivity.
    We focus on speeding up analysis by using big data platforms such as Apache Spark, automating portions of the data science life cycle, and improving the usability of the data science workbench.
  • Include multiple model deployment methods.
    Production models must be embedded in applications and business processes to provide business value. AMSTAT Consulting can deploy models in multiple ways, including as code embedded directly into applications, exposed as a service callable by applications, or injected into other platforms such as databases. Some of the more mature PAML (predictive analytics and machine learning) vendors include or are integrated with decision management platforms that allow AD&D pros and business users to use a visual metaphor or express decision logic as a set of business rules that can also include model
  • Provide sophisticated model management.
    The very nature of predictive models is that they may lose accuracy over time. More mature PAMl solutions include features to monitor the ongoing efficacy of models in production by comparing model output with established key performance indicators and testing new models using a champion/challenger or A/B testing scheme.
  • Allow polyglot programming.
    AMSTAT Consulting uses more than one programming language because of open-source add-on libraries such as CRAN for R and scikit-learn for Python.
  • Expand to Apache Spark.
    Apache Spark is an open-source, primarily in-memory cluster computing platform that also includes Spark Ml, a set of machine learning libraries that data scientists are increasingly interested in using. In addition to Spark Ml, other machine libraries such as H2o.ai’s sparkling Water and IBM’s SystemML run on Spark.
  • Build the foundation for AI and invest in deep learning.
    Machine learning models are a key building block of AI applications. We use any of the PAML solutions to build models for use in AI applications. Deep learning is a branch of machine learning that we use to build models based on artificial neural networks. This method is particularly good at creating models for image recognition (including facial recognition), but it is applicable to more traditional use cases as well. We incorporate numerous open source libraries, such as Caffe, MXNet, and TensorFlow, into PAML solutions, or they are creating their own deep-learning algorithms built into the platform.

Image result for machine learning, principal components analysis, image

We can use Principal Component Analysis in countless machine learning applications:

  • Fraud Detection
  • Word and Character Recognition
  • Speech Recognition
  • Email Spam Detection
  • Texture Classification
  • Face Recognition

Principal Component Analysis converts a set of possible correlated features into a set of linearly uncorrelated features called principal components.

We can reduce the dimensionality:

  • Reduce memory and disk space need to store the data
  • Reveal hidden, simplified structures
  • Solve issues of multicollinearity
  • Visualize higher-dimensional data
  • Detect outliers

We can visualize data after dimension reduction:

  • Which Medicare providers are similar to each other?
  • Which Medicare providers are outliers?
  • Further Exploratory Analysis
  • External Knowledge for Deeper Understanding of The Groups

Image result for principal components for machine learning, image

Image result for clustering for machine learning, image

Clustering is unsupervised learning.

  • No predefined classes
  • No examples demonstrating how the data should be grouped

Clustering is a method of data exploration.

  • A way of looking for patterns or structure in the data that are of interest
  • As a stand-alone tool to get insight into data distribution
  • As a processing step for other algorithms

Grouping

We can:

  • Group them based on what they do
  • Group them based on where they live
  • Use multiple variables and do cluster analysis with a similarity/dissimilarity measure
  • Cluster them based on their shopping behavior
  • Discover distinct groups in their customer data sets, and then use this knowledge to develop targeted marking programs (e.g., fresh food lovers, junk food lovers)

Major Clustering Approaches

  • Partitioning algorithm
    • We can construct various partitions and then evaluate them by some criterion
  • Hierarchical algorithms
    • We can create a hierarchical decomposition of the set of data using some criterion
      • Hard clustering: Each observation belongs to exactly one cluster
      • Soft clustering: An observation can belong to more than one cluster to a certain degree (e.g., likelihood of belonging to the cluster)

How to Choose a Clustering Algorithm

Depending on your problem, we can ask these questions:

  •  Is the algorithm scalable?
  • Does it handle different types of attributes?
  • Do you have to specify the number of clusters?
  • How much control do you have on the parameters and on the output?
  • How does it handle noise and outliers?
  • Is it sensitive to order of observations?
  • Can it handle high dimensional data?
  • Are the results interpretable?

K-means Clustering Summary

  • Advantage
    • Simple, understandable, efficient
    • Items automatically assigned to clusters
    • Can be used as a pre-clustering step
    • Other clustering algorithms can be applied on smaller sub-spaces.
  • Disadvantages
    •  Must pick number of clusters k
    •  All items forced into a cluster
    •  Too sensitive to outliers and noise
    • Does not work well with non-cluster cluster shape

Similarity vs Dissimilarity

  •  Depends on what we want to find or emphasize in the data
  •  Depends on the type of attributes in your data
  • Measures the relationship between 2 observations
  • Weighting the attributes might be necessary.
  • Some of the clustering algorithms use distance matrices as input.

Similarity

  • Cosine similarity
  • Inverse of distance measures values

Dissimilarity

  • Euclidean distance
  • Manhattan distance

Internal vs External

We can tell which clustering you need.

Internal criterion

  • Good clustering will produce high-quality clusters in which:
    • The intra-cluster similarity is high.
    • The inter-cluster similarity is low.

External criterion

  • Quality measured by its ability to discover some or all of the hidden patterns or latent classes in gold standard data
  • Assess a clustering with respect to ground truth

Estimating K: Reference Distribution

We can use the following methods to compare a clustering solution in the training data to a clustering solution in a reference distribution:

  • Aligned box criterion (ABC)
  • Gap statistic
  • Cubic clustering criterion (CCC)

When to Use Clustering

  • Segmentation
    • Customer, product, store
  • Anomaly detection
    • Outliers typically belong to clusters with 1 observation.
    • Identify fraud transactions
  •  Prepare for other techniques
    •  Summarize the documents =clusters and use centroids
  • Predictive modeling on segments
    • Logistic regression results can be improved by performing it on smaller clusters
  • Missing value imputation
  • Decrease dependence between attributes
    • Pre-processing step
