Peak Performance Analysis of the Track and Field 5000m Event

Peak Performance Analysis of the Track and Field 5000m Event

5000m is one of the most fascinating track and field disciplines to me. At first sight, a 5000m may seem short, especially if seen as running a “5km“. However, it assumes a different meaning when seen from the point of view of covering 12.5 laps on a track running close to the aerobic threshold: a single lap may feel endless. 5000m track race A mix of endurance and speed is required to master…

Challenging the memory of RL agents

Challenging the memory of RL agents

Reinforcement learning agents are usually trained to maximize their rewards by taking actions in an environment following a Markov Decision Process (MDP). A Markov Decision Process is simply a model that defines the state of an environment by its current state, actions, and rewards, including also its possible future states. MDP process The key point is that agents know information from the…

Exploring Transformer Model for Reinforcement Learning

Exploring Transformer Model for Reinforcement Learning

Transformers in RL MLP is widely used in RL to implement a learnable agent in a certain environment trained according to a specific algorithm. Recent works in NLP have already proved that Transformer can replace and outperform MLP in most tasks leading to expanding its utilization in areas outside of NLP such as Computer Vision. However, in RL the Transformer architecture is still not widely…

A scientific perspective of legs strength training for distance running

A scientific perspective of legs strength training for distance running

It is well known that strength training for distance runners provides a number of benefits that should be taken into consideration by both novel and more experienced runners. Primarily, strength training increases your strength and power, which will have a direct impact on your running performance. It also increases your running economy, which means you’ll be able to run faster with the same…

Speed benchmark einsum vs matmul in XL-Attention

Speed benchmark einsum vs matmul in XL-Attention

The original Transformer can only attend to a fixed and limited segment of the input to compute its attention. The major drawback of this architecture is that no information can flow across separated segments which prevents the Transformer to model long-term dependencies. Transformer-XL is an enhancement to the vanilla Transformer which enables the latter to store the most recent hidden states in…

Benefits of Contrast Hydrotherapy

Benefits of Contrast Hydrotherapy

Contrast showers, sometimes also known as contrast hydrotherapy, are showers in which our body temperature changes from hot to cold and back again by alternating between hot then cold water. A contrast shower usually consists of three to five complete cycles of hot and cold water. The hot water causes blood vessels to dilate, thereby pushing the blood to the skin’s surface, and cold water causes…
