机器学习学习路径
本文概述了从初学者到高级水平的机器学习学习路径,包括所需的知识领域、推荐的学习资源等,帮助读者根据自身需求选择合适的学习方向。

There are a few questions in the forums about what and where to learn Machine Learning(ML). The overview of this course also suggests some information during the last week of lectures. Since a lot of people look perplexed(including myself), I am trying tocreate a list of what to know in order to get good at ML. For the purpose of this discussion, I split knowledge required into three levels

  1. Beginner - knowing what ML is
  2. Intermediate - working on ML
  3. Advanced - living with ML

Common causes for learning ML

  1. Beginner - just curious, my boss/friend/GF/somebody asked to take it
  2. Intermediate - supporting a course at college, getting a job
  3. Advanced - data scientist, research

Knowledge level required

Beginner

  • Basic knowledge of algebra and probability
  • Good understanding of English

If the following terms sound familiar, then you are in good shape

algebra, solving equations, matrices, determinant, 2D plotting, graphs, polynomials

Intermediate

  • Solid grounding in basic algebra and linear algebra
  • Basic knowledge of calculus, probability and statistics
  • Basic programming knowledge

If the following terms sound familiar, then you are in good shape

eigen vectors,derivatives, binomial distribution, conditional probability, inequalities, regression, vector algebra, dot product

Advanced

Thorough knowledge in

  • Linear algebra
  • Statistics
  • Probability
  • Calculus - single and multi-variable and differential equations
  • Linear and convex optimization
  • Good programming knowledge with a programming language and a ML library

If the following terms sound familiar, then you are wasting your time reading this post

continuous random variables, prior and posterior distributions, hyper planes, t-distribution, hessian matrix,directed acylic graphs, Markov process, quasi convex functions, Chebyshev and Chernoff bounds, non-Euclidean space, mapreduce

Courses/Books

Beginner

Any course and any book would suffice. Andrew's course at Coursera is my preferred choice.

Intermediate

Andrew's course at Coursera and Yaser's course at Caltech. Plus a lot of programming with data. This would give a good insight into both theory and practice. Learning from Data provides a good introduction to fundamentals.

Advanced

In addition to the above,

I have taken the third option and my estimated to get good at it is from 3 -5 years.
More information on the above topic is welcome since I haven't described the exact areas to get good at.
