Overview of CPVT: A New Approach to Vision Transformers
If you're interested in artificial intelligence and computer vision, you might have heard of Vision Transformers, or ViT. ViT is a type of neural network that can “see” images and understand their features, allowing a computer to recognize what's in a picture. Recently, a new type of Vision Transformer has been developed, called Conditional Position Encoding Vision Transformer, or CPVT. In this article, we'll explain what CPVT is, how it w
What is Conditional Positional Encoding (CPE)?
Conditional Positional Encoding, also known as CPE, is a type of positional encoding used in vision transformers. It is different from traditional fixed or learnable positional encodings which are predefined and independent of input tokens. CPE is dynamically generated and is dependent on the local neighborhood of the input tokens. It has the ability to generalize to longer input sequences than the model has previously seen during training. CPE can
What are Conditional Random Fields (CRFs)?
Conditional Random Fields or CRFs are a type of probabilistic graph model that is used for various machine learning tasks such as classification and prediction. These models are designed to take into consideration neighboring sample context, which enables them to learn and accurately predict results based on these contexts.
How CRFs Work
CRFs work by building a graphical model, which includes dependencies between various predictions. The model's gra
CRN, or Conditional Relation Network, is a powerful tool used for representation and reasoning over video. It is a building block that takes an array of tensorial objects and a conditioning feature as inputs, and then computes an array of encoded output objects. This design supports high-order relational and multi-step reasoning, making it ideal for a wide range of applications.
What is CRN?
CRN is a machine learning architecture that is used to represent and reason about video data. It was f
Conditional Text Generation Overview: Generating Specific Text According to Conditioning
Have you ever tried to write a story but got stuck because you couldn't think of what to write next? Conditional text generation is here to help solve such problems. Conditional text generation is a type of artificial intelligence (AI) technology that generates written text according to some pre-specified conditions.
Conditional text generation is made possible by natural language processing (NLP), which i
What is CCAC?
If you're not familiar with Confidence Calibration with an Auxiliary Class, or CCAC for short, it is a post-hoc calibration method for Deep Neural Network (DNN) classifiers on Out-of-Distribution (OOD) datasets. In simpler terms, it is a technique that helps to improve the accuracy of artificial intelligence (AI) systems.
How does CCAC work?
One of the key features of CCAC is the use of an auxiliary class in the calibration model. The auxiliary class helps to separate mis-class
What is Conffusion?
Conffusion is a machine learning model that can be used to reconstruct a corrupted image. It uses a pretrained diffusion model to generate lower and upper bounds for each reconstructed pixel in the image. The true pixel value is guaranteed to fall within these bounds with a certain probability. Using Conffusion, you can efficiently recover an image that has been distorted or corrupted by noise or other factors, even if some of the pixels are missing or damaged.

Understanding CTC Loss: A Guide for Beginners
Connectionist Temporal Classification, more commonly referred to as CTC Loss, is a deep learning technique designed for aligning sequences, especially in cases where alignments are challenging to define. CTC Loss is especially useful when trying to align something like characters in an audio file, where the alignment is difficult to define.
CTC Loss works by calculating a loss between a continuous, unsegmented time sequence and a target sequence. T
Constrained Lip-synchronization: A Brief Introduction
Constrained lip-synchronization is the process of matching the lip movements in a video or an image to a target speech. This task requires a machine learning model that can learn the visual and acoustic features of the speech to accurately generate the corresponding mouth movement. However, the approaches used for constrained lip-synchronization can only work for a specific set of identities, languages, and speech.

Content-based attention is an attention mechanism used in machine learning that is based on cosine similarity. This mechanism is commonly used in addressing mechanisms, such as neural Turing Machines, to produce a normalized attention weighting.
What is Content-Based Attention?
In machine learning, content-based attention is a type of attention mechanism that is used to weight the relevance of different input components based on their similarity to one another. This is done by computing the c
The Content-Conditioned Style Encoder, also known as COCO, is a type of encoder used for image-to-image translation in the COCO-FUNIT architecture.
What is COCO?
COCO is a style encoder that differs from the traditional style encoder used in FUNIT. COCO takes both content and style images as input, allowing for a direct feedback path during learning. This feedback path enables the content image to influence how the style code is computed, which in turn reduces the direct influence of the styl
CABiNet: A Context Aggregation Network for Efficient Semantic Segmentation
As the demand for autonomous systems continues to increase, there is a greater need for efficient, real-time visual scene understanding. To address this need, researchers have proposed the Context Aggregation Network (CABiNet), a dual-branch convolutional neural network designed for pixelwise semantic segmentation.
Compared to other state-of-the-art methods, CABiNet offers significantly lower computational costs without
Context-Aware Product Recommendations
Recommendation systems have become an integral part of online shopping experiences. They are designed to analyze a user's behavior, preferences, and choices to provide intelligent recommendations for products or services. However, with the growth of e-commerce, there is a need for recommendation systems to be more intuitive and relevant to the user's specific needs. This is where context-aware product recommendation (CARS) becomes important.
