The main advantage of relational models is the ability to build dependencies between objects. That enables the structuring of the source data. The relational model can be represented in the form of graphs, in which objects and events are represented as nodes, while relationships show dependencies between objects and events. more...
Reinforcement learning is built on maximizing the reward received from the environment during interaction with it. Obviously, the learning process requires constant interaction with the environment. However, situations are different. When solving some tasks, we can encounter various restrictions on such interaction with the environment. A possible solution for such situations is to use offline reinforcement learning algorithms. They allow you to train models on a limited archive of trajectories ...
In this article, we will get acquainted with the Exploratory Data for Offline RL (ExORL) framework, which was presented in the paper "Don't Change the Algorithm, Change the Data: Exploratory Data for Offline Reinforcement Learning". The results presented in that article demonstrate that the correct approach to data collection has a significant impact on the final learning outcomes. This impact is comparable to that of the choice of learning algorithm and model architecture. more...
In the previous articles (Part 1, Part 2, Part 3), we experimented with shapes and angles whose values were passed to the perceptron and the neural network built on the basis of the DeepNeuralNetwork.mqh library. We also conducted experiments on optimization methods in the strategy tester. An important task in the current experiments was to track the influence of the amount of transmitted data and the depth of history we take this data from. In addition, we needed to reveal patterns, ...
Welcome to the third installment of our "Optimizing a Simple Hedging Strategy" series. In this segment, we'll begin with a brief review of our progress to date. So far, we have developed two key components: the Simple Hedge Expert Advisor (EA) and the Simple Grid EA. This article will focus on further refining the Simple Hedge EA. Our goal is to improve its performance through a combination of mathematical analysis and a brute force approach to find the most effective way to implement this ...
