A Friendly Introduction to Machine Learning



Luis Serrano

A friendly introduction to the main algorithms of Machine Learning with examples.
No previous knowledge required.

0:05 What is Machine Learning? Humans learn from past experiences, computers learn from previous data.
2:25 Linear Regression: Finding the line that works best between a given set of points.
4:10 Gradient Descent : Square of error minimization to get best line fit
6:20 Detecting Spam e-mails with Naive Bayes Algorithm
10:35 Decision Tree
13:20 Logistic Regression
17:00 Neural network as a logistic regression set intersection
18:50 Support Vector Machine with linear optimization
20:05 Kernel trick: planes for curves and vice-versa
26:00 K-Means clustering
28:30 Hierarchical Clustering
29:40 Summary
(Thanks to Nick Kartha for breaking down the topics!)

  2. Brilliant. Thank you so much..should have probably seen this before I took up a full fledged course in Machine Learning. Definitely learnt a lot more here!

  3. Brilliant, thank you for the excellent explanations of the algorithms. Very well presented, simple but effective. The slides and key points made make it appear simple, the time just flew watching the video.

  4. On the part of Cutting Data with Style (@19.22 in video clip), sir are actually demonstrating in the case of a few points, but if there is a large amount of datas, we can't just simply ignore the data point, just like you said we can ignore because it is out of boundary right??

  5. Great introduction to ML. No one does this better than you.
    Now I need to dig deeper into the algos that you introduced. Those will be the hard parts. Bu I do greatly enjoy the introductions. Thanks Luis!

  6. Well explained with awesome examples but a Programmer should have more practical knowledge to apply the appropriate algorithm to get right solutions having solid foundation knowledge on Mathematical Statistics, Algebra, Calculus, Theory of Probability else it will be elephant and blind men story. Kodus

  7. As someone who has taken an econometrics course (econ major) and now works as a Software Engineer on our NLP pipeline, this helps fill in the bits of knowledge that I'm lacking in machine learning! I didn't even know that's how naive bayes work.

  8. I was quite impressed with the way you have explained… its very easy to understand to even a primary students… great work… Please keep uploading such types of interactive videos..
