Linear algebra and calculus
Linear algebra and calculus are both used extensively in machine learning. Linear algebra provides the mathematical foundation for many of the algorithms used in machine learning, such as matrix operations and eigendecompositions. Calculus is used for optimisation, which is a key component in many machine learning algorithms. For example, gradient descent, which is used to train many types of neural networks, relies heavily on calculus to adjust the model's parameters in order to minimize the error. Additionally, Calculus also helps in understanding the behaviour of functions and their local minima/maxima, which is useful in understanding the optimization techniques used in ML. Overall, Linear Algebra and Calculus are essential tools for understanding and implementing many machine learning algorithms.
Probability and statistics
Probability and statistics are fundamental concepts that are used extensively in machine learning. They are used to model and analyze data, make predictions, and evaluate the performance of machine learning models.
Probability is used to represent the uncertainty in data, which is often modelled using probability distributions. This is important for understanding and modelling the relationships between variables in the data, and for making predictions.
Statistics are used to summarize and describe the data, and to make inferences about the underlying population from a sample of data. This is important for understanding the characteristics of the data, and for selecting appropriate models and algorithms for the task at hand.
Probability and statistics are used for feature selection, feature engineering, and model selection. They also play a key role in evaluating and comparing the performance of different machine learning models. For example, hypothesis testing, p-value, Bayesian inference, Maximum Likelihood Estimation, etc are all statistical concepts used in ML.
Overall, probability and statistics are essential tools for understanding and working with data in machine learning, and for developing and evaluating machine learning models.
3. Programming
Programming is an essential tool for implementing machine learning algorithms and building machine learning systems. It allows data scientists and engineers to translate mathematical models and algorithms into working code that can be run on a computer.
In machine learning, programming is used to:
Collect, clean and prepare the data for modelling.
Implement and test different machine learning algorithms and models.
Train and fine-tune models using large datasets.
Evaluate the performance of models using metrics like accuracy and error.
Deploy machine learning models in production environments, such as web applications or mobile apps.
Popular programming languages used in machine learning include Python, R, Matlab, Java and C++. These languages have a wide range of libraries and frameworks that make it easy to implement machine learning algorithms, such as TensorFlow, scikit-learn, and Keras.
Overall, programming is a critical skill for anyone working in machine learning, as it allows them to implement and test the models they develop, and to build systems that can be used in real-world applications.
4. how do Specific machine learning algorithms help in learning machine learning?
Different machine learning algorithms have different strengths and weaknesses and are suited for different types of tasks and datasets. Some common examples include:
Linear regression and logistic regression are simple and easy to understand and are often used for basic prediction tasks.
Decision trees and random forests are powerful for classification and regression tasks and can handle non-linear relationships and missing data.
Support vector machines (SVMs) are effective for high-dimensional and non-linearly separable data.
Neural networks and deep learning are extremely powerful and flexible and are used for a wide range of tasks including image and speech recognition, natural language processing and more.
k-nearest neighbours is a simple algorithm that is used for classification and regression tasks.
Gradient Boosting Machine (GBM) is used for both classification and regression tasks and is a powerful algorithm for handling imbalanced and non-linearly separable data.
There are many other algorithms such as Naive Bayes, K-means, etc which are used for specific tasks.
In summary, different machine learning algorithms are well suited for different types of datasets and tasks, and choosing the right algorithm for a specific problem can make a big difference in the performance of a machine learning model.

5. Deep learning
Deep learning is a subset of machine learning that uses artificial neural networks with multiple layers to learn and make predictions or decisions. These neural networks are inspired by the structure and function of the human brain and are used for tasks such as image and speech recognition, natural language processing, and decision-making. Deep learning algorithms can automatically learn features from large amounts of data, making them particularly useful for tasks where traditional rule-based approaches are not feasible.
