The Problem of Overfitting 到现在为止,我们已经见识了几种不同的学习算法,包括线性回归和逻辑回归。 但是,当将它们应用到某些特定的机器学习应用时,会遇到过度拟合(over-fitting)的问题,可能会导致它们效果很差。 但是有一种称为正则化(regularization)的技术 它可以改善或者减少过度拟合问题,以使学习算法更好实现 。
solving the problem of overfitting:regularization 发生的在linear regression上面的overfitting问题 发生在logistic regression上面的overfitting 怎么解决overfitting regularization: cost function of linear regression parameters小的话,这样hypothesis就会变得简单,这样就不会overfitting 一般不会对θ0进行regularization 上式是进...
Building Alpha Go was by no means a small feat, requiring the brightest minds in machine learning to spend years of their lives to solve this problem. Once they built the Deep Reinforcement Learning machine, the machine itself could learn the game of Go. But building this machine was still ...
Research relevant to problem solving and learning using trigonometric processes is described in Part I. The incorporation of learning into the process of mechanically proving trigonometric identities presents a unique and major step in the field of artificial intelligence. The processes used, and indeed...
2.4 Problem Solving approach When solving a problem using traditional machine learning algorithm, it is generally recommended to break the problem down into different parts, solve them individually and combine them to get the result. Deep learning in contrast advocates to solve the problem end-to-en...
This process involves organizing the data in a suitable format, such as a CSV file or a database, and ensuring that the data is relevant to the problem you're trying to solve. Step 2: Data preprocessing Data preprocessing is a crucial step in the machine learning process. It involves ...

Owing to factors such as the development of faster computers, availability of open-source software and the access to vast amounts of computational data, AI has now branched into machine learning (ML), probabilistic predictions, chaos theory and evolutionary computation. Investing in artifici...
Artificial intelligence happens when humans synthetically create a sense of human-like intelligence within a machine. For machine learning, this means programming machines to mimic specific cognitive functions that humans naturally possess, such as perception, learning, and problem-solving. ...
Problem When solving machine learning problems, simply training a model based on a problem-specific training machine learning algorithm does not guarantee either that the resulting model fully captures the underlying concept hidden in the training data or that the optimum parameter values were chos...
