Online Hard Example Mining

Object detection datasets often include a large number of easy examples and only a few difficult ones, which can make training difficult. To address this issue, researchers have developed **OHEM**, or **Online Hard Example Mining**, which is a technique that improves the efficiency and effectiveness of training by automatically selecting difficult examples for training. What is OHEM? OHEM is a bootstrapping technique that modifies SGD, or Stochastic Gradient Descent, to selectively sample exa

Online Multi-granularity Distillation

Understanding OMGD If you have ever heard of GANs, you may have come across something called OMGD. OMGD stands for Online Multi-Granularity Distillation, which is a fancy way of saying it is a framework for helping computers learn to make things like images or music. But what exactly does that mean? What are GANs? First, let's talk about GANs. GAN stands for Generative Adversarial Networks, which are a type of artificial intelligence that can create new things. You can think of GANs like an

Online Normalization

Online Normalization is a technique used for training deep neural networks. In simple terms, it replaces arithmetic averages over the entire dataset with exponentially decaying averages of online samples. This helps in achieving a better convergence rate while training the neural network. What is Online Normalization? Online Normalization is a normalization technique that helps in training deep neural networks in a faster and more accurate manner. It replaces arithmetic averages over the full

Detecting these parts and predicting their motion parameters is critical in many computer vision applications, including robotics, autonomous driving, and augmented reality. OPD

Open-Domain Question Answering

Open-domain question answering is a type of task that aims to answer questions on open-domain data sets, such as the vast array of information found on Wikipedia. The goal is to provide accurate and relevant answers to questions in a way that simulates human intelligence, while relying purely on machine learning algorithms to do so. What is Open-Domain Question Answering? Open-domain question answering is a part of natural language processing that aims to answer questions posed to it by human

Open Information Extraction

Open Information Extraction - An Overview Open Information Extraction (OIE) is a method used in Natural Language Processing (NLP) to extract structured and machine-readable representations of the information present in a text. The goal is to extract the meaning of the text in the clearest and simplest way possible to create triples or n-ary propositions. What is Open Information Extraction? Open Information Extraction is a type of information extraction that uses a machine-learning algorithm

Open Knowledge Graph Canonicalization

Open Knowledge Graph Canonicalization: A Beginner's Guide If you've ever used a search engine like Google, you've probably noticed that it can return a lot of results. Often, you'll see similar or duplicate information in the results, which can be confusing. This can happen because the information is stored in what's called an Open Knowledge Graph, which doesn't identify equivalent entities and relations. This is where Open Knowledge Graph Canonicalization comes in. What is Open Knowledge Gra

Open Set Learning

Open set learning (OSL) is a new approach to the traditional concept of supervised learning. It is a more realistic and challenging way to train classifiers to detect test samples that fall outside of the training data. This means that the labels of the test samples may be from classes that were not seen during training. The Open Set Recognition Sub-task The sub-task of open set recognition (OSR) involves the detection of test samples that do not belong to the training set. In other words, OS

Opinion Mining

Opinion mining, also known as sentiment analysis, is the practice of identifying and categorizing opinions expressed in a piece of text. This is done to determine whether the writer's attitude towards a particular topic, product, or service is positive, negative, or neutral. The process of opinion mining involves using natural language processing and machine learning techniques to analyze large volumes of text data such as customer reviews, social media posts, news articles, and more. How Opin

Optical Character Recognition (OCR)

Optical Character Recognition (OCR) is a technology used to convert typed, handwritten or printed text into machine-encoded text. This conversion can be performed using electronic or mechanical devices. The technology is commonly used for scanning documents and photos to extract text from them. How Does OCR Work? OCR works by analyzing the shapes and patterns of text characters in an image. The technology uses complex algorithms to identify the patterns and convert them into machine-readable

Orientation Regularized Network

Overview of Orientation Regularized Network (ORN) Orientation Regularized Network (ORN) is a technique used for pose estimation that allows for the fusion of multiple views of an object in order to gain a more accurate understanding of its orientation. Specifically, ORN makes use of IMU orientations as a structural prior to mutually fuse the image features of each pair of joints linked by IMUs. This allows for the fusion of the features of the elbow to reinforce the ones found at the wrist for

Orthogonal Regularization

Orthogonal Regularization: A Technique for Convolutional Neural Networks Convolutional Neural Networks (ConvNets) are powerful machine learning tools used for a variety of tasks, such as image recognition and classification.
