Verbal description
Constellate analysis is a staple of unsupervised machine learning and information scientific discipline.
IT is very useful for data mining and big data because it automatically finds patterns in the information, without the need for labels, unlike supervised automobile learning.
In a real-human race environment, you can imagine that a automaton or an AI won't always have access to the optimal answer, or maybe there isn't an optimum correct answer. You'd deprivation that automaton to beryllium able to explore the world on its own, and learn things just past looking for patterns.
Do you ever wonder how we get the data that we use up in our supervised machine learning algorithms?
We always seem to have a nice CSV or a set back, complete with Xs and same Ys.
If you haven't been up to her neck in acquiring data yourself, you mightiness non have thought about this, but soul has to make this data!
Those "Y"s have to come from somewhere, and a lot of the time that involves manual labor.
Sometimes, you Don River't have access to this kind of information or it is infeasible or expensive to acquire.
But you still desire to have any idea of the structure of the data. If you're doing data analytics automating model recognition in your information would Be invaluable.
This is where unattended simple machine learning comes into act as.
Therein course we are first going to talk about clustering. This is where instead of grooming on labels, we try to create our own labels! We'll do this by pigeonholing unitedly data that looks alike.
There are 2 methods of clustering we'll talk about: k-means bunch and hierarchical clustering.
Succeeding, because in machine learning we like to talk about chance distributions, we'll enter Gaussian motle models and kernel density estimation, where we talk of how to "memorise" the chance statistical distribution of a set of information.
One fascinating fact is that under certain conditions, Gaussian mixture models and k-means clustering are on the button the same! We'll examine how this is the case.
All the algorithms we'll discourse in this course are staples in car learning and data science, so if you want to love how to mechanically find patterns in your information with data excavation and pattern extraction, without needing person to put in manual work to label that data, and so this course is for you.
All the materials for this course are FREE. You tin download and install Python, Numpy, and Scipy with simple commands happening Windows, Linux, or Mac.
This course focuses on "how to human body and understand", not just "how to use". Anyone can learn to use an API in 15 proceedings subsequently recital some documentation. It's not roughly "remembering facts", it's about"seeing for yourself" via experimentation. It will teach you how to visualize what's natural event in the model internally. If you wantmore than retributory a superficial look at machine learning models, this course is for you.
"If you can't implement it, you don't understand it"
- Or as the cracking physicist Richard Phillips Feynman said: "What I cannot create, I do not empathise".
- My courses are the ONLY courses where you will learn how to go through machine learning algorithms from scratch
- Other courses wish teach you how to connect your data into a program library, but do you really need assist with 3 lines of code?
- After doing the same thing with 10 datasets, you realize you didn't learn 10 things. You scholarly 1 thing, and just repeated the same 3 lines of encipher 10 times…
Suggested Prerequisites:
- ground substance addition, multiplication
- probability
- Python steganography: if/else, loops, lists, dicts, sets
- Numpy coding: matrix and vector operations, loading a CSV file
WHAT ORDER SHOULD I Choose YOUR COURSES IN?:
- Check away the lecture "Machine Learning and AI Prerequisite Roadmap" (available in the FAQ of any of my courses, including the absolve Numpy course)
Who this course is for:
- Students and professionals interested in machine learning and data science
- People who wishing an introduction to unsupervised machine learning and cluster analysis
- People WHO want to know how to write their own clustering code
- Professionals concerned in information mining big data sets to look for patterns mechanically
