Study Notes

Machine Learning Fundamentals

The primary objective of classification in machine learning is to assign labels or categories to new, unseen data based on patterns learned from a training dataset.
Identification in machine learning involves determining the category or class of an instance, and an example of this is image recognition, where the task is to identify the objects in an image.

Regression in Machine Learning

The primary objective of regression in machine learning is to predict a continuous or numerical value based on input features.

Clustering in Machine Learning

The primary purpose of clustering in machine learning is to group similar instances or data points into clusters based on their characteristics, without prior knowledge of the group labels.

Recognition in Machine Learning

Recognition in machine learning involves identifying patterns or objects in data, such as speech, images, or text, and an example of this is speech recognition, where the task is to recognize spoken words and phrases.

Machine Learning vs Traditional Programming

Machine learning is used when the problem is too complex to be solved by traditional programming, as it involves learning from data and improving over time.

Machine Learning Goals

The main goal of machine learning is to enable machines to learn from data and make decisions or predictions without being explicitly programmed.

Classification Applications

An example of a classification application is sentiment analysis, where the task is to classify text as positive, negative, or neutral.

Statistics in Machine Learning

The role of statistics in machine learning is to provide a mathematical framework for understanding and modeling data, and for making predictions or decisions.

Data and Knowledge

The primary difference between data and knowledge in the context of machine learning is that data refers to the raw, unprocessed information, whereas knowledge refers to the useful patterns, relationships, and insights extracted from the data.

Data Preprocessing

The process of extracting usable data from a larger set of raw data is called data preprocessing or data wrangling.

Machine Learning in Medicine

The main applications of machine learning in medicine include disease diagnosis, image analysis, and personalized medicine.

Unsupervised Learning

An example of an unsupervised learning application is customer segmentation, where the goal is to group customers based on their characteristics and behaviors.

Model Building

The aim of building a model in machine learning is to make predictions, classify new instances, or make recommendations based on the patterns learned from the data.

Classification

Classification in machine learning refers to the process of assigning labels or categories to new, unseen data based on patterns learned from a training dataset.

Market Basket Analysis

An example of a market basket analysis association is identifying the products that are frequently purchased together, such as milk and cereal.
