Lossfunction helps in evaluation and optimization. Understanding different types of lossfunctions and their applications is important for designing effective deep learning models.
Summary: Loss functions measure the error between a model’s predictions and actual values. Common types include binary cross-entropy and hinge loss for classification, and MSE, MAE, Huber, log-cosh and quantile loss for regression, each suited to different data characteristics.
Learn about loss functions in machine learning, including the difference between loss and cost functions, types like MSE and MAE, and their applications in ML tasks.
In supervised learning, there are two main types of lossfunctions – these correlate to the 2 major types of neural networks: regression and classification lossfunctions
At its core, a lossfunction is incredibly simple: it’s a method of evaluating how well your algorithm models your dataset. If your predictions are totally off, your lossfunction will output a higher number. If they’re pretty good, it’ll output a lower number.
Different types of lossfunctions exist to handle specific tasks such as classification and regression, or quantifying absolute differences between actual and predicted values.
This chapter introduces 21 lossfunctions in traditional machine learning algorithms, including 11 lossfunctions for classification problems, 6 lossfunctions for regres-sion problems and 4 lossfunctions for unsupervised learning.
Different lossfunctions are suited for different types of problems. Here are some common lossfunctions with an easy-to-understand explanation, their usage, and examples:
This difference, or "loss," guides the optimization process to improve model accuracy. In this article, we will explore various common lossfunctions used in machine learning, categorized into regression and classification tasks.
