在人工智能的快速发展中,深度学习已成为众多领域的重要工具,包括图像识别、自然语言处理和预测建模等。然而,深度学习模型通常需要大量的标记数据来进行训练,这不仅消耗大量时间,而且需要大量的计算资源。这里,主动学习(Active Learning)出现了,它通过智能地选择有代表性的数据样本来进行标记和训练,从而减少了所需的数据量和计算成本。

主动学习(Active Learning)专注于对数据集的研究(注重样本的选取,而非模型训练),又称查询学习(Query Learning),目标是用最少的标签来获取最好的性能。AL猜想在当前模型中同一数据集的不同样本有不一样的价值,并且尝试在未标记的数据集中选择高价值的样本作为训练集,将其交给Oracle(如人工标记器)进行标记。深度学习...
Deep Active Learning 最上方为监督学习,对面为非监督学习,之间包括增强学习、半监督学习、在线学习、主动学习。 Supervised Learing 将未标记的数据交给Work进行标记,然后将标记数据交给Learner进行训练。 Semi-Supervised Learning 在监督学习的基础上加了一条线,也就是把大量的未标记数据和少量的标记数据交给Learner进行...

深度学习的基本原理是基于人工神经网络,输入信号经过非线性的active function,传入到下一层神经元;再经过下一层神经元的activate,继续往下传递,如此循环往复,直到输出层。正是因为这些active functions的堆砌,深度学习才被赋予了解决非线性问题的能力。当然,仅仅靠active functions还不足于使得深度学习具有"超能力",训练过...

Deep learning (DL) models achieved a lot of success due to the availability of labeled training data. In contrast, labeling a huge amount of data by a human is a time-consuming and expensive solution. Active Learning (AL) efficiently addresses the issue of labeled data collection at a low ...
