以下是给定的英文文本：
Machine learning is the scientific study of algorithms and statistical models that computer systems use to perform a specific task without using explicit instructions, relying on patterns and inference instead. It is seen as a subset of artificial intelligence. Machine learning algorithms build a mathematical model based on sample data, known as "training data", in order to make predictions or decisions without being explicitly programmed to perform the task.
机器学习是指计算机系统使用的算法和统计模型的科学研究，以在不使用显式指令的情况下，依赖于模式和推理来执行特定任务。它被视为人工智能的一个子集。机器学习算法基于样本数据（称为“训练数据”）构建数学模型，以便在没有被明确编程执行任务的情况下进行预测或决策。
