Overview of Relational Reasoning
Relational Reasoning is a problem-solving method that aims to understand the relationships between different entities, such as image pixels, words, or even complex human movements. This approach is used in a variety of fields, including computer science and artificial intelligence. By understanding how the different entities are connected, relational reasoning helps in predicting future outcomes, recognizing patterns, and making decisions.
Relational reasoning
Relationship extraction is a process that takes place in the field of Natural Language Processing (NLP). The aim of this process is to identify the connections between different entities in a text. These entities may be people, organizations or locations. The relationships between them can be of various types such as familial or organizational links. This is a very important task as it helps in categorizing and understanding the content of a text.

Overview of Relative Position Encodings
Relative Position Encodings are a type of position embeddings used in Transformer-based models to capture pairwise, relative positional information. They are essential in various natural language processing tasks, including language modeling and machine translation.
In a traditional transformer, absolute positional information is used to calculate the attention scores between tokens. However, this approach is limited as it does not differentiate between
What is a Relativistic GAN?
A Relativistic GAN, or RGAN for short, is a type of generative adversarial network designed to improve the performance of standard GANs. A standard GAN consists of a generator and a discriminator, where the generator generates fake data and the discriminator distinguishes between real and fake data. The goal of a GAN is to train the generator to create data that is indistinguishable from real data, and the discriminator to accurately distinguish between real and fake
What is ReLIC?
ReLIC stands for Representation Learning via Invariant Causal Mechanisms, and is a type of self-supervised learning objective that allows for improved generalization guarantees. It does this by enforcing invariant prediction of proxy targets across augmentations through an invariance regularizer.
How Does ReLIC Work?
ReLIC works by using a proxy task loss and Kullback-Leibler (KL) divergence to calculate similarity scores. Concretely, it associates every datapoint with a label
ReLU6: A Modified Version of Rectified Linear Unit
Machine learning algorithms are rapidly changing the computational landscape of artificial intelligence. The rectified linear unit (ReLU) is one of the most popular activation functions used in deep learning models. ReLU functions have been known to offer better performance compared to other activation functions like sigmoid or hyperbolic tangent. The ReLU6 function is a modification of the original ReLU function designed to improve its robustn
In modern healthcare, hospital stays and ICU admissions are an important facet of patient treatment, and over the past several years, there has been a growing demand for ways to predict how long patients may need to stay in the ICU. These predictions can help inform medical planning, improve patient care, and ultimately make healthcare more efficient.

Remaining length of stay (RLOS) is a prediction of how long a patient needs to remain in the ICU based on the
Understanding Replacing Eligibility Trace in Reinforcement Learning
Reinforcement learning is a type of machine learning where an algorithm is trained to learn the optimal behavior in a specific environment. One of the key elements of reinforcement learning is the concept of eligibility traces. Eligibility traces are used to update the value function of an agent in a way that takes into account not only the current reward but also the recent history of the agent's actions.
