在机器学习和计算机视觉等领域,ground truth指的是真实的、正确的或最佳的结果,作为对比模型的预测或分类结果的参考。例如,在图像分类任务中,ground truth可能是人工标注的正确的图像类别,而模型的输出是预测的图像类别。在这种情况下,我们可以通过计算模型的准确率来评估模型的性能,也就是模型预测的图像类别与ground truth之间的差异。
Ground truth
Ground truth refers to the actual or objective information about a phenomenon that is being studied or observed. It is often used as a reference or benchmark against which other information or data can be compared or validated. In the field of machine learning and artificial intelligence, ground truth is used to train and test algorithms by providing a set of labeled data that can be used to evaluate the accuracy and effectiveness of the model. Ground truth can be obtained through direct observation, measurement, or expert knowledge.
