Understanding the Fundamentals of Machine Learning
Machine learning is crucial in today’s data-driven world, where the ability to extract insights and make predictions from vast amounts of data can help significant advancement in any field thus understanding its fundamentals becomes crucial.
We can see machine learning as a subset or just a part of artificial intelligence that focuses on developing algorithms that are capable of learning hidden patterns and relationships within the data allowing algorithms to generalize and make better predictions or decisions on new data. To achieve this we have several key concepts and techniques like supervised learning, unsupervised learning, and reinforcement learning.
- Supervised learning involves training a model on labeled data, where the algorithm learns from the input data and its corresponding target ( output labels). The goal is to map from input to output, allowing the model to learn the relationship and make predictions based on the learnings of new data. Some of its algorithms are linear regression, logistic regression decision trees, and more.
- Unsupervised learning, on the other hand, deals with the unlabeled dataset where algorithms try to uncover hidden patterns or structures within the data. Unlike supervised learning which depends on labeled data to create patterns or relationships for further predictions, unsupervised learning operates without such guidance. Some of its algorithms are, Clustering algorithms like k-means, hierarchical clustering dimensionality reduction algorithms like PCA, and more.
- Reinforcement learning is a part of machine learning that involves training an agent to interact with an environment and learn optimal actions through trial and error. It employs a reward-penalty strategy, the agent receives feedback in the form of rewards or penalties based on its actions, allowing it to learn from experience and maximize its reward over time. Reinforcement learning applications in areas such as robotics, games, and more.
Some of the key terminologies of ML before building one are:
- Feature: Features are the pieces of information that we use to train our model to make predictions. In simpler terms, they are the columns or attributes of the dataset that contain the data used for analysis and modeling.
- Label: The output or target variable that the model aims to predict in supervised learning, also known as the dependent variable.
- Training set: The portion of the dataset that is used to train the machine learning model. The model learns patterns and relationships in the data from the training set.
- Validation set: A subset of the dataset that is used to tune the model’s hyperparameters and helps in assessing performance during training of the model.
- Test Set: It is also a part of the dataset that is used to evaluate our final model performance on unseen data.
Steps to Build a Machine Learning Model
In today’s era of a data-rich environment where data generation volume, velocity, and variety are unparalleled, we face both opportunities and challenges. Machine learning models offer a powerful mechanism to extract meaningful patterns, trends, and insights from this vast pool of data, giving us the power to make better-informed decisions and appropriate actions. In this article, we will explore the Fundamentals of Machine Learning and the Steps to build a Machine Learning Model.
