  Ways to combat retraining depend on the algorithm and consist of the correct values of the trainer's met parameters. In practice, model estimation is not performed on the same input data that was used to train the model. Divide 10-20% of all available data into a separate set and call it a set for evaluation. We will bring the other 10-20% into the set for ratification, and 60-80% of the remaining ones will be given to the trainer. The principle of data sharing depends on the data and the task. Random sampling is often a good method if inputs are independent of each other, and there is no strong imbalance between the number of positive and negative entries. 
  The intuitive analogy here is the same as with university studies: the teacher solves some problems with students in pairs and gives other’s similar tasks in the exam. What is important here (both in teaching students and models) is that these tasks are varied, and students cannot simply memorize the answers, and those who have mastered the material (similar tasks) will be able to repeat the thought process and answer correctly. 
  In machine learning, we split into data two sets: we will use the evaluation set to evaluate each model we train, using different approaches, algorithms, and model types to select the best one. That is, for each model, we will have two precision values - precision on the training dataset and precision on the evaluation dataset. It is normal for the former to be higher than the second, but not significantly. A big difference indicates retraining.

  How the World Flows acts like a microscope that pulls the listener into the barely noticeable, Lilliputian world of fluids at small scales—the microfluidic world—and answers the question "What is microfluidics?" in non-technical language.Microfluidics is the field of science that studies fluids constrained to spaces that are smaller than one millimeter wide, and by extension, the engineering field which builds devices that exploit the unique properties of fluids at these scales. Author Albert Folch explores this micro science which has inspired engineers to build devices such as engines, spray cans, ballpoint pens, inkjet and 3D printers, pregnancy and Covid tests, glucometers, asthma nebulizers, kidney dialysis machines, and DNA analyzers.This book also shows that many processes essential to life on Earth—such as the formation of raindrops, the rise of sap in plants, and the percolation of water through soil—are all microfluidic marvels. It examines how our cells breathe, feed, and fight diseases through small capillaries. Through engaging and digestible stories, Folch takes a lens to this tiny science and demonstrates how big a role microfluidics play in life as we know it.

  Human Anatomy - A Comprehensive...

  The human body is a remarkable and intricate system, made up of trillions of cells working in harmony to maintain life. Understanding its structure and function is essential for gaining insights into how the body operates and sustains itself. At the most basic level, the body is organized into four primary levels: cells, tissues, organs, and systems. Cells are the building blocks of life, each with specialized functions that contribute to the overall well-being of the organism. Tissues are formed from similar cells working together to perform specific functions. Organs are composed of various tissues that cooperate to carry out more complex tasks, and when organs work together in coordinated groups, they form systems that carry out essential bodily functions. 
  The organization of the body is designed for efficiency and survival, ensuring that all processes, from digestion to respiration, occur seamlessly. For example, the digestive system processes food and absorbs nutrients, the respiratory system ensures oxygen exchange, and the circulatory system distributes oxygen and nutrients to the cells while removing waste products. Each system is interconnected, and any disruption to one can affect the others, highlighting the importance of balance and coordination in maintaining health. 
  A key concept in understanding the body’s functioning is homeostasis, the body’s ability to maintain a stable internal environment despite external changes. This balance is critical to the survival of cells and, by extension, the organism as a whole. The body’s systems are continuously monitoring and adjusting to changes in temperature, pH levels, fluid balance, and other internal factors to keep everything within optimal ranges. For instance, when body temperature rises, the body sweats to cool down, and when it drops, it shivers to generate heat. Similarly, the kidneys help regulate fluid balance by adjusting urine production according to hydration levels.
