In 2020, the “butterfly effect” was triggered in China’s pharmaceutical industry, with the two wings of this butterfly being the introduction of the MAH system and the initiation of centralized procurement. The MAH system is of great significance in encouraging drug innovation and improving drug quality. According to the MAH system, the drug marketing authorization … Read more
With the continuous development of genetics, breeding, and the increasing advancements in the Human Genome Project and molecular biology, biological data has experienced explosive growth over just a few decades. For example, algorithms such as regression analysis, random forests, and support vector machines in bioinformatics are already quite mature. Recently, while reading literature, I came … Read more
1 Algorithm Introduction XGBoost, short for eXtreme Gradient Boosting, is an ensemble learning algorithm based on Gradient Boosting Decision Trees (GBDT). It improves upon GBDT by introducing regularization terms and second-order derivative information, enhancing model performance and generalization ability. As an efficient ensemble learning algorithm, XGBoost effectively utilizes multi-core processors for parallel computing, accelerating the … Read more
Reprinted from:Author: james_aka_yale In the field of machine learning, there is a saying: “There is no free lunch in the world,” which means that no single algorithm can perform best on every problem. This theory is particularly important in supervised learning. For example, you cannot say that neural networks are always better than decision trees, … Read more
