What is Machine Learning?
Machine Learning refers to the field of study and practice that enables computer systems to learn and improve from data without explicitly being programmed. In other words, it is a subset of artificial intelligence (AI) that focuses on the development of algorithms and models that allow machines to learn and make predictions or decisions based on data.
Basic Concepts of Machine Learning
1. Training Data: In order for a machine learning model to learn, it needs to be trained on a set of data. This data, known as training data, should be representative of the problem or task that the model is being trained for.
2. Features: Features, also known as input variables or independent variables, are the characteristics or attributes of the data that serve as the basis for making predictions or decisions. These can be numerical, categorical, or textual in nature.
3. Labels: Labels, also known as target variables or dependent variables, are the desired outcomes or the values that the machine learning model aims to predict or classify. For example, in a spam email detection model, the labels would be “spam” or “not spam”.
4. Algorithms: Machine learning algorithms are sets of mathematical rules or procedures that are applied to the training data in order to learn patterns, relationships, or rules. These algorithms vary depending on the type of problem, such as regression, classification, or clustering.
5. Training: During the training phase, the machine learning model uses the training data and the selected algorithm to adjust its internal parameters or weights in order to minimize the errors or differences between the predicted outcomes and the actual labels.
6. Evaluation: After the training phase, the performance of the machine learning model is assessed using a separate set of data called the evaluation data. This allows us to measure how well the model generalizes to unseen data and whether it has learned the underlying patterns or relationships.
7. Prediction: Once the machine learning model is trained and evaluated, it can be deployed to make predictions or decisions on new or unseen data. This is done by feeding the unseen data into the model and obtaining the predicted outcomes or classifications.
Machine Learning: Basic Concepts for Beginners
