Autoencoderは、データの効率的な表現を学習するためのニューラルネットワークの一種です。特に、異常検知や次元削減、データのノイズ除去などに利用されます。 Autoencoderには、EncoderとDecoderがあります。 Encoder（エンコーダー）: 入力データを圧縮して、低 ...

Dr. James McCaffrey of Microsoft Research provides full code and step-by-step examples of anomaly detection, used to find items in a dataset that are different from the majority for tasks like ...

本記事ではAutoEncoderをPytorchで実装します。ライブラリ紹介ではなく実装がメインのため学習シリーズに近い内容となります。 AutoEncoderの特徴は下記の通りです。 情報を圧縮することで軽い動作で使用できる。 ー＞本記事では784次元の画像を200次元（潜在 ...

Abstract: Masked Autoencoder (MAE) has shown remarkable potential in self-supervised representation learning for 3D point clouds. However, these methods primarily rely on point-level or low-level ...

This study aims to explore an autoencoder-based method for generating brain MRI images of patients with Autism Spectrum Disorder (ASD) and non-ASD individuals, and to discriminate ASD based on the ...

An image autoencoder may be used to learn a compressed representation of an image. An autoencoder comprises two parts: an encoder, which learns a representation of the image, using fewer neurons than ...

Abstract: A stacked autoencoder (SAE) is a widely used deep network. However, existing deep SAEs focus on original samples without considering the hierarchical structural information between samples.
