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
