A Primer on Machine Learning

Explore the fascinating realm of machine learning, a cornerstone of computational sciences, characterized by algorithms that empower machines to learn autonomously. Delve into its diverse forms, including supervised, unsupervised, and reinforcement learning.

• Supervised Machine Learning
  Understand the intricacies of supervised learning systems, which master data classification through initial examples. These systems are deemed 'supervised' as the learning trajectory is influenced by the examples chosen by the designer overseeing the project.
• Unsupervised Machine Learning
  Step into the world of unsupervised machine learning where training examples are unlabelled, presenting a unique challenge as the algorithm lacks predefined reference points for data classification.
• Reinforcement Learning
  Reinforcement learning stands out as a unique paradigm in machine learning. Here, an agent evolves through experience and feedback from its actions, guided by a reward-based system that encourages goal-oriented behaviors.

Neural Network

Discover neural networks, sophisticated computational models mirroring biological neurons. These interconnected artificial neurons are at the forefront of numerous practical applications, prominently in machine learning.

Deep Learning

Deep learning, a subset of machine learning, employs neural networks with multiple hidden layers, enabling a deeper and more complex processing of information layer by layer.

The Essence of Linear Regression

Linear regression, a statistical method, is used to model and analyze relationships between a dependent variable and one or more independent variables, assuming a linear interconnection. This technique aims to identify the line or multi-dimensional plane that best fits the data, minimizing the variance between observed points and the predicted line.

Hidden Markov Models (HMM)

A Hidden Markov Model (HMM) represents a sophisticated statistical approach, wherein a sequence of observable events is derived from an underlying, and typically unobservable, Markov process. Essential elements of an HMM encompass the presence of hidden states, a chain of observations, state transition probabilities, observation likelihoods, and the initial probability distribution of the states as the process commences.
