Autoencoder

释义 Definition

自编码器:一种神经网络模型,目标是把输入数据先“压缩”为较小的表示(编码),再尽量“还原”回原始输入(解码),常用于降维、特征学习、去噪与异常检测。(也有多种变体,如去噪自编码器、稀疏自编码器、变分自编码器等。)

例句 Examples

An autoencoder can compress images into a small vector.
自编码器可以把图像压缩成一个较小的向量表示。

By training an autoencoder on normal sensor readings, the system can flag anomalies when reconstruction error becomes unusually high.
将自编码器在正常传感器读数上训练后,当重建误差异常升高时,系统就能标记出异常情况。

发音 Pronunciation (IPA)

/ˌɔːtoʊɪnˈkoʊdər/

词源 Etymology

auto- 表示“自我、自动”,encoder 表示“编码器”。合起来字面意思是“自我编码/自我还原的编码器”,强调模型用自身学到的表示来重建输入数据。
