If you dont have business problem, then you can’t possibiliy come up with machine learning algorithm and model to answer what you are trying figure out.
Terminology
What is a model?
Model is a trained algorithm
which is
- Used to identify patterns in your data, and
- Does not require explicit, manually set rules.
Supervised
Learn by identifying data that is already been labeled
. We have/had data to train
Classification:
- Binary (Yes or No)
- Multiclass Classfication (like tags. Ex: possible answers for call center - “IT Support”, “Returns”, “Accounting”)
- Regression problem (Range)
Unsupervised
There is no existing data points to train. We just have raw data. The machine has to uncover and create the labels
itself.
- use data grouping.
- detects annomolies.
Reinforcement Learning
Learning through trial and error.
