Residual connections, or skip connections, refers to the architectural motif of +, where is an arbitrary neural network module. This gives the gradient of ∇ f + I {\displaystyle \nabla f+I} , where the identity matrix do not suffer from the vanishing or exploding gradient.
Every residual connection is a skip connection, but almost all skip connections are not residual connections. The original Highway Network paper [ 16 ] not only introduced the basic principle for very deep feedforward networks, but also included experimental results with 20, 50, and 100 layers networks, and mentioned ongoing experiments with up ...
U-Net is a convolutional neural network that was developed for image segmentation. [1] The network is based on a fully convolutional neural network [2] whose architecture was modified and extended to work with fewer training images and to yield more precise segmentation.
During the late 1980s, "skip-layer" connections were sometimes used in neural networks. Examples include: [17] [18] Lang and Witbrock (1988) [19] trained a fully connected feedforward network where each layer skip-connects to all subsequent layers, like the later DenseNet (2016). In this work, the residual connection was the form () + (), where ...
Here is the output of the th node (neuron) and is the weighted sum of the input connections. Alternative activation functions have been proposed, including the rectifier and softplus functions. More specialized activation functions include radial basis functions (used in radial basis networks , another class of supervised neural network models).

Skip zone is the subject of a film 'SKIPZONE' made in 1992 by UK artist, Peter Lee-Jones. It refers to areas in Scottish Highlands where it is difficult to obtain radio and TV reception. [citation needed] In the episode "Short Wave" [1] of Father Knows Best, the family hears a distress call from a small boat at sea. Jim explains that the reason ...
SKIP and Photuris were evaluated as key exchange mechanisms for IPsec before the adoption of IKE in 1998. [ 1 ] Simple Key Management for Internet Protocols (SKIP) is similar to SSL, except that it establishes a long-term key once, and then requires no prior communication in order to establish or exchange keys on a session-by-session basis.
