Episode 3 : Data science and Machine Learning

In this episode, we juxtapose the different types of Machine Learning: supervised, unsupervised, semi-supervised, and reinforcement.

What is the difference between data science and machine learning?

• Machine learning is a sub-discipline within data science
• Machine learning is an application of artificial intelligence
• Machine learning is predictive analytics
• Prescriptive analytics and recommending a path forward

The different types of machine learning: supervised, unsupervised, semi-supervised, and reinforcement learning

Supervised machine learning: data is labeled and we know the outcome, using a predictive model and comparing your predicted results to the labeled outcomes.

• Classic examples of churn and spam vs non-spam
• Classification vs regression problems and how they differ

Unsupervised machine learning: data is not labeled and we don’t know the outcome.

• Clustering using a distance metric is involved, and we can get the attributes of different clusters
• Latent dich allocation (LDA) for topic modeling (categories not defined beforehand)

Semi-supervised machine learning

• Turning an unsupervised program into a supervised learning problem
• How do we determine accuracy and precision of semi-supervised machine learning?

Reinforcement learning

• Self-driving cars examples
• A car will make mistakes, a penalty system will prevent those mistakes from re-emerging in the future
• The AI agent continuously learns based on a set of penalties that are imposed
• There will be a growth in reinforcement learning in the future
