Machine Learning and Artificial Intelligence

Advancements for Electrical Inspection


Publicized Milestones• January 2011 Watson beats long standing

Jeopardy Champion• Amazon’s Jeff Bezos – “Big trends are not

that hard to spot. We are in the middle of oneright now. Machine Learning and ArtificialIntelligence.”


Facial Recognition


AI is Broadest of Terms


Artificial Intelligence• Mimic Human Intelligence

– Using Logic, If-Then Rules, Decision Trees• ML statistical techniques that enable machines to

improve a task with experience• Big data is large volumes of data used for

computational analysis, to reveal patterns or trends


Neural Network• A computer system designed to work by

classifying information similar to the same way a human brain functions

• Taught to recognize images– classify the images, including the components or sub-

elements– Probability statement, decisions or predictions with a

degree of certainty or statistical probability


Glossary of Terms• Artificial Intelligence (AI) – A.I. is the broadest of term, applying to any technique that enables computers to mimic human intelligence, using logic,

if-then rules, decision trees and machine learning.

• Machine Learning (ML) – The subset of A.I. that includes statistical techniques that enable machines to improve at task with experience.

• Big Data – Large volumes of data sets that are used for computational analysis, to reveal patterns or trends.

• Deep Learning – The subset of machine learning composed of algorithms that permit software to train itself to perform tasks, like speech and image recognition, by exposing multilayered neural networks to vast amounts of data.

• Neural Networks – Software constructions modeled after the way adaptable networks of neurons in the brain are understood to work, rather than through rigid instructions predetermined by humans.

• Bayesian Networks – A probabilistic graphical model or type of statistical model that represents a set of variables and their conditional dependencies. For example, a Bayesian network could represent the probabilistic relationships between electric outages and a individual electric grid component anomaly. Given the component anomaly type, the Bayesian Network can be used to compute the probabilities of an outage.

• Clustering – During the supervised learning phase of inputting data for training, a subject matter expert selects or targets input features to be utilized in the learning models. In clustering or unsupervised learning, the target features are not given in the training examples. The goal is to construct a natural classification that can be used to cluster the data. The general idea behind clustering is to partition the examples into clusters or classes. Each class predicts feature values for the examples in the class. Each clustering has a prediction error on the predictions. The best clustering is the one that minimizes the error.
