## What is fully convolutional neural networks?

Fully Convolutional Networks, or FCNs, are an architecture used mainly for semantic segmentation. They employ solely locally connected layers, such as convolution, pooling and upsampling. Avoiding the use of dense layers means less parameters (making the networks faster to train).

## What is full CNN?

A Convolutional Neural Network (ConvNet/CNN) is a Deep Learning algorithm which can take in an input image, assign importance (learnable weights and biases) to various aspects/objects in the image and be able to differentiate one from the other.

## Is U net a fully convolutional network?

UNET Architecture and Training The UNET was developed by Olaf Ronneberger et al. for Bio Medical Image Segmentation. Thus it is an end-to-end fully convolutional network (FCN), i.e. it only contains Convolutional layers and does not contain any Dense layer because of which it can accept image of any size.

## What is Long et al?

Long et al. [60] used dense FCN for semantic segmentation, which combines dense downsampling layers and deconvolution layers (upsampling) to enhance spatial precision of the output.

## How does fully convolutional network work?

The fully convolutional network first uses a CNN to extract image features, then transforms the number of channels into the number of classes via a 1×1 convolutional layer, and finally transforms the height and width of the feature maps to those of the input image via the transposed convolution.

## What is a U Net model?

The u-net is convolutional network architecture for fast and precise segmentation of images. U-net architecture (example for 32×32 pixels in the lowest resolution). Each blue box corresponds to a multi-channel feature map. The number of channels is denoted on top of the box.

## What is fully convolutional networks?

Fully convolutional networks are a class of networks that use nothing but convolutional filters and non linearities.

## What is fully connected neural network?

Fully connected neural network, called DNN in data science, is that adjacent network layers are fully connected to each other. Every neuron in the network is connected to every neuron in adjacent layers. A very simple and typical neural network is shown below with 1 input layer, 2 hidden layers, and 1 output layer.

## What can convolutional neural network do?

The convolutional neural network, or CNN for short, is a specialized type of neural network model designed for working with two-dimensional image data, although they can be used with one-dimensional and three-dimensional data. Central to the convolutional neural network is the convolutional layer that gives the network its name.

## Is convolutional neural network a black box?

Deep learning with convolutional neural networks (CNNs) has achieved great success in the classification of various plant diseases. However, a limited number of studies have elucidated the process of inference, leaving it as an untouchable black box.
