Unsupervised Contextual Anomaly Detection

Unsupervised Contextual Anomaly Detection: What it means and how it works If you've ever been to a bank, you may have seen an alarm go off if someone tries to rob it. That alarm is an example of supervised anomaly detection, where a system is taught what is normal and what is not. However, sometimes there are rare events or objects that the system has not seen before, and that's where unsupervised anomaly detection comes in. Unsupervised anomaly detection is like having a system that can detect

Unsupervised Deep Manifold Attributed Graph Embedding

Deep Manifold Attributed Graph Embedding (DMAGE) is a novel graph embedding framework that aims to tackle the challenge of unsupervised attributed graph representation learning, which requires both structural and feature information to be represented in the latent space. Existing methods can face issues with oversmoothing and cannot directly optimize representation, thus limiting their applications in downstream tasks. In this article, we will discuss the DMAGE framework and how it can be used t

Unsupervised Domain Adaptation

Unsupervised Domain Adaptation is the process of transferring knowledge from one area/domain with labeled data to another area/domain with no labeled data. In this learning framework, the source domain provides a large amount of labeled and annotated data, while the target domain has only unlabeled data available for learning. The goal of unsupervised domain adaptation is to train models that can generalize well to the target domain and improve performance by using the knowledge learned from the

Unsupervised Facial Landmark Detection

Facial landmark detection in the unsupervised setting is a technique that enables computers to recognize and locate specific points on a human face without the need for manual input by human experts.

The ability of computers to recognize faces has improved significantly in recent years, thanks to the development

Unsupervised Feature Loss

What is UFLoss? UFLoss, or Unsupervised Feature Loss, is a type of deep learning (DL) model used for reconstructions. It has been designed to provide instance-level discrimination by mapping similar instances to similar low-dimensional feature vectors using a pre-trained mapping network (UFLoss Network). The purpose of UFLoss is to capture mid-level structural and semantic features that are not found in small patches. What Are the Advantages of Using UFLoss? The main advantage of using UFLos

Unsupervised Few-Shot Learning

Unsupervised Few-Shot Learning: Understanding the Basics Machine learning has come a long way in recent years. With the ability to learn from data, computers can perform tasks that previously required human intelligence. However, most machine learning systems require large amounts of labeled data to be effective, which can be a time-consuming and expensive process. Few-shot learning is an exciting area of research that aims to overcome this issue, by training models to recognize new classes wit

Unsupervised Image-To-Image Translation

Unsupervised image-to-image translation is a technique used to convert an image into another image without any prior knowledge of pairings between the two. This task is performed without any ground truth image-to-image pairings, and the output image is completely new and unrelated to the input image. The Basics of Unsupervised Image-to-Image Translation To perform unsupervised image-to-image translation, a system uses a generative adversarial network (GAN) to train itself to map an input imag

Unsupervised Machine Translation

Unsupervised machine translation is a type of machine translation where there are no translation resources used during training. In simple terms, the machine is not given any information about the language pair it needs to translate between or any pre-existing dictionaries or phrase tables. Instead, it learns on its own by analyzing large amounts of raw text in both languages. The traditional approach to machine translation Traditional machine translation is usually done using supervised lear

Unsupervised Part-Of-Speech Tagging

Understanding Unsupervised Part-Of-Speech Tagging Have you ever wondered how the words in a sentence are understood by a machine? One way to achieve this is through Part-Of-Speech (POS) tagging, which involves marking up each word in a text to identify its corresponding part of speech. For example, identifying whether a word is a noun, verb, adjective or adverb. This process is important for natural language processing tasks such as text classification, sentiment analysis, and machine translati
