一、 机器学习类别 机器学习按照学习数据经验的不同,即训练数据的标签信息的差异,可以分为监督学习(supervised learning)、非监督学习(unsupervised learning)、半监督学习(semi- supervised learning)和强化学习(reinforcement learning)。 1.1 监督学习 监督学习是机器学习中应用最广泛及成熟的,它是从有标签的数据样本(x...
- 有监督学习(Supervised learning) 通过大量已知的输入和输出相配对的数据,让计算机从中学习出规律,从而能针对一个新的输入做出合理的输出预测。比如,我们有大量不同特征(面积、地理位置、朝向、开发商等)的房子的价格数据,通过学习这些数据,预测一个已知特征的房子价格,这种称为回归学习(Regression learning),即输出结...
监督学习 监督学习supervised learning:机器学习中最常见的类型,它可以学会将输入数据映射到已知目标annotation。比如回归问题和分类问题(二分类、多分类问题等)是最常见的监督学习的例子。 其他监督学习的应用例子: 序列生成sequence generation 语法树预测syntax tree prediction 目标检测object detection 图像分割image segment...
监督学习(supervised learning)和无监督学习(unsupervised learning)是两个重要的机器学习模型。从长远来看,任何立志于从事人工智能或机器学习领域工作的人都需要学习它们,并了解实现它们的各种技术。这里我认为有必要简单说明两种模型之间的区别了。假设有两个人分别叫 A 和 B,他们要把苹果和橘子分成两组。他们从未见过...
Supervised learningPythonCode comments can provide a great data source for understanding programmer's needs and underlying implementation. Previous work has illustrated that code comments enhance the reliability and maintainability of the code, and engineers use them to interpret their code as well as ...
Random Forest In Python(Code) Support Vector Machine Algorithm A Support Vector Machine (SVM) is a discriminative classifier formally defined by a separating hyperplane. In other words, given labeled training data (supervised learning), the algorithm outputs an optimal hyperplane that categorizes new ...

Through the use of TensorDict, TorchRL's training loops are made very similar to regular training loops in supervised learning (although the "dataloader" -- read data collector -- is modified on-the-fly): Code env_make = lambda: GymEnv("Pendulum-v1", from_pixels=True) collector = ...
The general goal of machine learning is to build models that can learn from data without being explicitly programmed. Among the many subdomains of machine learning, the one that usually gets the most attention is what is known as supervised learning. It is the most accessible, especially for ...
