What did I do :

• Today we did the exercise for the current topic with friends for attendance.
• Discussing Cluster techniques with Simpson’s family as an example from the slide.
• Discussing all kinds of calculation with some example of simple data sets （Manhattan).

Obstacles/Difficulties :
The difficulty of today is doing the exercise because it takes a lot of time if the answer did not match what we expected. since the task needs several repetitions of calculation if we did not reach the answer.

What did I learn:
Today we learn about a topic called “learning by observation”. This topic consists of types of matching learning, clustering technique, manhattan, hierarchal and Euclidean calculation on data, K-means algorithm
