Overview of ILVR
Iterative Latent Variable Refinement, also known as ILVR is a method that is used to guide the generative process in denoising diffusion probabilistic models (DDPMs) for generating high-quality images based on a given reference image. DDPM’s are a type of model that is capable of generating high-quality images that are similar to real-life images. However, at times, these images may not be able to hold certain semantics or features that are desired by the user. In such cases, I
What is IPL?
Iterative Pseudo-Labeling (IPL) is a semi-supervised algorithm used in speech recognition. The algorithm fine-tunes an existing model using both labeled and unlabeled data. IPL is known for efficiently performing multiple iterations of pseudo-labeling on unlabeled data as the acoustic model evolves.
How Does IPL Work?
IPL works by utilizing unlabeled data, which is not labeled with the correct transcriptions of speech, along with the labeled data, to fine-tune the existing model
What is Jigsaw?
Jigsaw is a machine learning approach that is used to improve image recognition tasks in computer vision. It is a self-supervision approach that relies on jigsaw-like puzzles as the pretext task in order to learn image representations.
The idea behind Jigsaw is that by solving jigsaw-like puzzles using image patches, the model can learn to recognize and piece together different parts of an image, thereby building up an understanding of what each part means and how they relate t
Joint Entity and Relation Extraction: An Overview
Joint entity and relation extraction is a natural language processing (NLP) task that involves identifying and extracting entities (i.e. named entities such as person, organization, and location) and the relations between them from natural language text. It can be used to automate the extraction of structured data from unstructured data sources, making it a valuable tool for various applications such as information retrieval, data mining, and kn
JLA: Revolutionizing Object Tracking and Trajectory Forecasting
The Joint Learning Architecture, or JLA, is an innovative approach to tracking multiple objects and forecasting their trajectories. By jointly training a tracking and trajectory forecasting model, JLA enables short-term motion estimates in place of traditional linear motion prediction methods like the Kalman filter.
The base model of JLA is FairMOT, which is known for its detection and tracking capabilities. The architecture of JL
What is JPEG Artifact Correction?
When we capture a digital image, it is usually saved in a compressed format called JPEG. This file format is widely used because it helps reduce the size of the image and makes it easier to share and store. JPEG compression, however, also causes some visual artifacts in the image called blocking, blurring, and ringing. These artifacts can detract from the quality of the image and make it appear less sharp and detailed.
That's where JPEG artifact correction com
Jukebox: Generating Music with Singing in Raw Audio Domain
If you are a fan of music, you might be interested in a new model that generates music with singing in the raw audio domain. It's called Jukebox. The model is designed to tackle the long context of raw audio using a multi-scale VQ-VAE to compress it to discrete codes, and modeling those using autoregressive Transformers. It can condition on artist and genre to steer the musical and vocal style and on unaligned lyrics to make the singing
k-Means Clustering: An Overview
k-Means Clustering is a type of algorithm used in machine learning that helps classify data into different groups based on their similarity to one another. By dividing a training set into k different clusters, k-Means Clustering can assist in finding patterns and trends within large datasets. This algorithm is commonly used in fields such as marketing, finance, and biology to group together similar data points and better understand the relationships between them.

Understanding k-Medians: Definition, Explanations, Examples & Code
The k-Medians algorithm is a clustering technique used in unsupervised learning. It is a partitioning method of cluster analysis that aims to partition n observations into k clusters based on their median values. Unlike k-Means, which uses the mean value of observations, k-Medians uses the median value of observations to define the center of a cluster. This algorithm is useful in situations where the mean value is not a good rep
Understanding k-Nearest Neighbor: Definition, Explanations, Examples & Code
The k-Nearest Neighbor (kNN) algorithm is a simple instance-based algorithm used for both supervised and unsupervised learning. It stores all the available cases and classifies new cases based on a similarity measure. The algorithm is named k-Nearest Neighbor because classification is based on the k-nearest neighbors in the training set. kNN is a type of lazy learning algorithm, meaning that it doesn't have a model to t
K-Net: A Unified Framework for Semantic and Instance Segmentation
K-Net is a framework for semantic and instance segmentation that uses a set of learnable kernels to consistently segment instances and semantic categories in an image. This framework uses a simple combination of semantic kernels and instance kernels to allow panoptic segmentation. It learns the kernels by using a content-aware mechanism that ensures each kernel responds accurately to varying objects.

What is a k-Sparse Autoencoder?
A k-Sparse Autoencoder is a type of neural network that achieves sparsity in the hidden representation by only keeping the k highest activities in the hidden layers. This means that only a small number of units in each hidden layer are activated at any given time, allowing for more efficient and accurate processing of data.
How Does a k-Sparse Autoencoder Work?
A k-Sparse Autoencoder has two main components: the encoder and the decoder. The encoder takes in an

K3M is a cutting-edge pretraining method for e-commerce product data that integrates knowledge modality to address missing or noisy image and text data. It boasts of modal-encoding and modal-interaction layers that extract features and model interactions between modalities. The initial-interactive feature fusion model maintains the independence of image and text modalities, while a structure aggregation module fuses information from
Kaiming Initialization, also known as He Initialization, is an optimization method for neural networks. It takes into account the non-linear activation functions, such as ReLU, to avoid the problem of reducing or magnifying input signals exponentially. This method ensures that each layer of the neural network receives the same amount of variance, making it easier to optimize.
Why Initialize Neural Networks?
Neural networks, at their core, are just a collection of mathematical functions. Each
