Introduction to FCOS: An Anchor-Box Free Object Detection Model
If you're someone who is interested in computer vision, you might have come across the term "object detection". Object detection is a crucial task in computer vision, where the objective is to detect objects present in an image or video. Over the past few years, many object detection models have been developed, and one such model is called FCOS.
FCOS stands for Fully Convolutional One-Stage Object Detection, and it is an anchor-bo
FCPose is a cutting-edge technology used for multi-person pose estimation. It is built on top of the FCOS object detector and eliminates the need for region of interest operations and post-processing grouping.
Understanding FCPose
FCPose is a fully convolutional framework that is used for multi-person pose estimation. It uses dynamic instance-aware convolutions to eliminate the need for ROI operations and grouping pre-processing. The dynamic keypoint heads used in FCPose are conditioned on ea
Are you familiar with the concept of person search networks? If not, let us introduce you to AlignPS, or Feature-Aligned Person Search Network.
What is AlignPS?
AlignPS is an efficient anchor-free framework for person search. It uses a specific architecture, which is similar to the anchor-free detection model called FCOS.
The model of AlignPS is designed to make it more focused on the re-identification (re-id) subtask. It does this by using an aligned feature aggregation (AFA) module. This m
Overview of FFMv1: A Feature Fusion Module from the M2Det Object Detection Model
FFMv1, or Feature Fusion Module v1, is a component of the M2Det object detection model. Feature fusion modules play an essential role in creating the multi-level feature pyramid required for object detection. They utilize 1x1 convolution layers to reduce the channels of input features and a concatenation operation to combine feature maps. FFMv1 involves two feature maps from different scales in the backbone and a s
Feature Fusion Module v2, or FFMv2, is an important module in the object detection model known as M2Det. Its primary function is to combine the features from different levels to create a final, multi-level feature pyramid.
What is M2Det?
M2Det is an object detection model that aims to accurately and efficiently detect objects within an image. The model is based on the concept of feature pyramids, which involves combining features at multiple scales to achieve better accuracy.

What is FIERCE?
FIERCE is a concept used in the field of machine learning and artificial intelligence. It refers to an entropic regularization on the feature space. But what does that mean?
In order to understand this concept fully, we need to review some basic terminology. A feature is a characteristic of a dataset that is used to build a machine learning model. For example, in an image classification problem, features might include the color of the pixels or the textures and shapes that are
What is Feature Intertwiner?
Feature Intertwiner is a revolutionary module used for object detection that focuses on leveraging the features of a more reliable set of data to guide the feature learning of a less reliable set. With Feature Intertwiner, there is a mutual learning process that enables two sets to have a closer distance within the cluster in each class.
How Does Feature Intertwiner Work?
Feature Intertwiner is specifically developed to be used on the object detection task. To ad
Have you ever heard of Feature Pyramid Grids, or FPG? It may sound complicated, but it’s actually a deep learning method that’s used for image analysis and recognition. FPG is a multi-pathway feature pyramid that represents the feature scale-space as a regular grid of parallel bottom-up pathways, which are fused by multi-directional lateral connections.
What is FPG?
FPG is a method that connects the backbone features of a convolutional neural network (ConvNet) with a regular structure of para
What is a Feature Pyramid Network?
A **Feature Pyramid Network**, or **FPN**, is an artificial neural network used for object detection in images. Specifically, it is a feature extractor that takes a single-scale image of an arbitrary size as input and outputs proportionally sized feature maps at multiple levels. This allows for the detection of objects at different scales within an image.
How Does FPN Work?
The construction of the pyramid involves a bottom-up pathway and a top-down pathway.
Feature selection is an important process that involves selecting the most relevant features or predictors for use in building a model. Depending on the dataset, there could be several features that are not necessary for the model construction or could even cause noise in the model, which could lead to inaccurate predictions or results.
What is Feature Selection?
Feature selection involves choosing the most relevant features from a dataset that will be used for developing a new predictive mod
Overview of Feature Non-Maximum Suppression (FeatureNMS)
Feature Non-Maximum Suppression, or FeatureNMS, is an essential component in object detection models. It is a post-processing step that identifies and removes duplicated detections outputted per object. In other words, FeatureNMS helps ensure that object detection models accurately identify each object instance by filtering out duplicate or overlapping detections.

Object detection is a computer vision techniqu
Feedback Memory in the Feedback Transformer Architecture
Feedback Memory is a type of attention module used in the Feedback Transformer architecture. This allows for the most abstract representations from the past to be directly used as inputs for the current timestep. The model does not form its representation in parallel, but rather sequentially token by token. Feedback Memory replaces the context inputs to attention modules with memory vectors that are computed over the past. This means that
A Feedback Transformer is a type of sequential transformer that utilizes a feedback mechanism to expose all previous representations to all future representations. This unique architecture allows for recursive computation, building stronger representations by utilizing past representations.

Feedforward Network: Understanding the Basics
What is a Feedforward Network?
A feedforward network is a type of neural network architecture that consists of input nodes, output nodes, and one or more hidden layers of processing nodes between them. In a feedforward network, information flows only in one direction - from the input nodes, through the hidden layers, and to the output nodes. The nodes within each layer are densely connected, meaning that each node within one layer is connected to
Few Shot Action Recognition: An Introduction to the Computer Vision Challenge
Few shot action recognition is a computer vision problem that aims to classify an unlabelled video into one of several defined action categories. The challenge arises from the limited number of training samples available in the support set for each action class. This is often referred to as shot, which mainly depends on the size and diversity of the training dataset.

Introduction to Few-Shot Learning
Have you ever had to learn something new with very little information to go off of? Maybe you had only a few examples or samples to work with, and had to generalize what you learned to apply it to a larger set of problems. This is exactly the same challenge of few-shot learning.
