The Position-Wise Feed-Forward Layer is a type of feedforward layer that has become popular in deep learning. The layer is made up of two dense layers that are applied to the last dimension of a sequence. This means that the same dense layers are used for each position item in the sequence, which is why it is called position-wise.
What is a Feedforward Layer?
In deep learning, a feedforward layer is a type of neural network layer that takes the input data and applies a set of weights and bias
Positional Encoding Generator: An Overview
If you have ever encountered natural language processing or machine translation, then you may have come across the term positional encoding. A positional encoding is a mechanism that helps a neural network understand the order and sequence of tokens in a sequence. It does this by encoding each token with a unique set of numbers that represent its position in the sequence. This way, the neural network can differentiate each token based on its context or
Overview of Powerpropagation
Powerpropagation is a technique for training neural networks to create sparse models. In traditional neural networks, all parameters are allowed to adapt during training, leading to a dense network with many unnecessary parameters that don't contribute to the model's performance. By selectively restricting the learning of low-magnitude parameters, Powerpropagation ensures that only the most relevant parameters are used in the model, making it more efficient and accu
Overview of PowerSGD: A Distributed Optimization Technique
If you're someone who is interested in the field of machine learning, you may have come across PowerSGD. PowerSGD is a distributed optimization technique used to approximate gradients during the training phase of a model. It was introduced in 2018 by DeepMind, an artificial intelligence research lab owned by Google.
Before understanding what PowerSGD does, you need to have a basic understanding of what an optimization algorithm is. In

Precise RoI Pooling: An Overview
Precise RoI Pooling (PrRoI Pooling) is a feature extractor that is designed to identify and extract a region of interest (RoI) in an image. RoI pooling is a technique that first segments an image into different regions and then takes a feature map as input, which is then used to further extract the features from the identified RoI. PrRoI pooling is a significant improvement over traditional RoI pooling methods and is used in several modern computer vision applic
