Restricted Boltzmann Machines
Restricted Boltzmann Machines, or RBMs, are types of neural networks that can learn to represent probability distributions over inputs. RBMs are used in various applications such as dimensionality reduction, feature learning, collaborative filtering, and generative modeling.
How RBMs Work
RBMs have two layers of nodes, the visible layer and the hidden layer. Nodes in the visible layer represent the inputs, while nodes in the hidden layer represent latent feature

The retina is a thin layer of tissue located at the back of the eye that plays a crucial role in vision. It is responsible for capturing visual images and transmitting them to the brain via the optic nerve. However, various diseases and conditions may cause damage to the retina, resulting in vision loss and other complications.
One of the most common methods for detecting and diagnosing retinal diseases is the use of Optical Coherence Tomography

Retrace is a Q-value estimation algorithm used in reinforcement learning. It works best when there are two policies, a target policy and a behavior policy, denoted as $\pi$ and $\beta$, respectively. The algorithm uses off-policy rollout for TD learning, meaning that it uses data generated by following one policy while trying to learn about another policy.
Importance Sampling
In Retrace, importance sampling is used for the update of Q-values. Importance sampling is a technique used in statist
Reversible Residual Blocks are a new way of building convolutional neural networks (CNNs). They are a part of the RevNet architecture, which is a recent development in CNNs. RevNet is special because it tries to make CNNs easier to work with and use less computer power. One way it does this is by using reversible residual blocks.
What are Residual Blocks in CNNs?
To understand what reversible residual blocks are, we need to first understand what a residual block is. A residual block is a set

RevNet: A Reversible Residual Network
A RevNet, otherwise known as a Reversible Residual Network, is a type of deep neural network architecture that was developed as a variation on ResNet, which stands for Residual Network. The main difference between these two types of networks is that in a RevNet, each layer's activations can be reconstructed exactly from the next layer's. This means that very few activation values need to be stored in memory during backpropagation. As a result, RevNets requi
RevSilo is an innovative multi-input multi-output coupling module that provides a bidirectional multi-scale feature pyramid fusion experience that is completely invertible. The concept of invertibility lies at the heart of the module, allowing for the preservation of information across multiple scales of an image or video feed. By applying this principle, RevSilo can create a seamless composite that effectively combines visual data from multiple sources into a unified whole.
