1. Linear Algebra for Machine Learning
👉 Why you should learn linear algebra for machine learning?

In machine learning, most of the time we deal with scalars and vectors, and matrices. For example in logistic regression, we do vector-matrix multiplication. Sometimes we do clustering of input by using spectral clustering techniques, and for this, we need to know eigenvalues and eigenvectors. Linear algebra is also used in data preprocessing, data transformation, dimensionality reduction, and model evaluation.

👉 What are some of the core topics you should learn in linear algebra?

Topics such as Principal Component Analysis (PCA), Singular Value Decomposition (SVD), Eigen decomposition of a matrix, LU Decomposition, QR Decomposition/Factorization, Symmetric Matrices, Orthogonalization & Orthonormalization, Matrix Operations, Projections, Eigenvalues & Eigenvectors, Vector Spaces and Norms are needed for understanding the optimization methods used for machine learning

2. Probability and Statistics for Machine Learning
👉 What's the use of probability and statistics in machine learning?

Probability helps you to manage the uncertainty. Uncertainty means working with imperfect or incomplete information. And in Machine Learning, we build predictive models from uncertain data. But we can manage uncertainty using the tools of probability. Whereas Statistics help you to count well, normalize well, obtain distributions, find out the mean of your input feature, and its standard deviation. That’s why knowledge of Probability and Statistics is important for machine learning.

👉 What are some of the core topics you should learn in stats and probability?

Some of the fundamental Statistical and Probability Theory needed for ML are Combinatorics, Probability Rules & Axioms, Bayes’ Theorem, Random Variables, Variance and Expectation, Conditional and Joint Distributions, Standard Distributions (Bernoulli, Binomial, Multinomial, Uniform and Gaussian), Moment Generating Functions and more.

3. Calculus for Machine Learning
👉 What's the use of calculus in machine learning?

Calculus helps us to explain the relationships between input and output variables. And Multivariate Calculus comes into the picture when you deal with a lot of features and huge data. That’s why familiarity with multivariate calculus is essential for building a machine learning model.

👉 What are some of the core topics you should learn in calculus?

Some of the necessary topics include Differential and Integral Calculus, Partial Derivatives, Vector-Values Functions, Directional Gradient, Hessian, Jacobian, Laplacian and Lagragian Distribution.

4. Optimizations Methods & Other Topics for Machine Learning
👉 What's the use of optimization in machine learning?

Optimization methods are important to understand the computational efficiency and scalability of our Machine Learning Algorithm. In the end, mostly all Machine learning algorithms come down to some optimization tasks.

👉 What are some core topics you should learn in optimization methods?

Knowledge of data structures (Binary Trees, Hashing, Heap, Stack etc), Dynamic Programming, Randomized & Sublinear Algorithm, Graphs, Gradient/Stochastic Descents and Primal-Dual methods are needed.

Other important disciplines can include continuous functions limits, information theory, real and complex analysis (Sets and Sequences, Topology, Metric Spaces, Single-Valued and Continuous Functions, Limits, Cauchy Kernel, Fourier Transforms) and Manifolds.
