  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.

  That One Patient: Doctors and...

  THE INTERNATIONAL BEST SELLER FEATURING INTERVIEWS WITH DR ANTHONY FAUCI, DAME SALLY DAVIES AND DR JIM DOWN 
  For every doctor there is that one patient, whose story touches them in a way they didn’t expect, changing their entire outlook on life. This inspiring and deeply moving book is the story of those patients. 
  Every weekend, in Holland’s most popular newspaper, de Volkskrant, renowned science-journalist Ellen de Visser asks a different medical professional to tell her about ‘that one patient’; the patient who changed everything for them. 
  Every day, in every country, thousands of patients share their stories with their doctors: stories they may never have told anyone else; stories that are heartbreaking, sometimes funny, and – just occasionally – unforgettable. To be able to do their job to the best of their abilities, medical experts use their ‘professional empathy’: they sympathize with their patients but try to keep themselves at a distance. But there is always that one patient who, for whatever reason, bridges this distance and often unwittingly, has a lasting impact on their doctor’s life. 
  There’s the dying patient whose decision to donate their organs would save the lives of five different people, bringing incredible comfort to the family they left behind. Or the little girl who showed clear evidence of having been beaten by an adult, but who remained too loyal to her step-father to say a word. There’s the little boy, diagnosed with life-threatening malaria in a Sudanese refugee camp, whose astonishing survival against the odds still inspires their doctor each time they stand by the bed of a child who looks unlikely to make it. And there’s the cancer patient whose love of cycling and unflagging optimism inspired his oncologist in ways he could never have imagined. 
  That One Patient is brimming with intimate stories of connection and of the unanticipated ways we can affect one other’s lives. All of them remind us of just how extraordinary humans can be, and of our incredible capacity for bravery, strength and humour. 
  In That One Patient, Ellen de Visser delves into the social aspects of caregiving, presenting a biography of sorts for each physician and their unforgettable patients. The top-notch autobiography style narrative brings to life the philosophy of death and life from a unique perspective. 
  For fans of Christie Watson (Quilt on Fire), Linda Watson-Brown (Sins of the Father), Henry Marsh (And Finally), Abraham Verghese (My Own Country), and Ed Patrick (Catch Your Breath).

  Smart Trader: The Psychology and...

  Trading is often painted as a world of numbers, algorithms, and quick decisions. But behind the charts and tickers lies something much deeper—the mind of the trader. I have written The Smart Trader to explore this often overlooked aspect of trading, where psychology, discipline, and emotion meet strategy, risk, and execution. 
  Over the years, I’ve met countless traders who knew all the right strategies, had all the technical tools at their disposal, and yet, struggled to make consistent profits. Why? Because trading is not just about understanding the markets. It’s about understanding yourself. Success in trading is rooted in mastering your emotions, managing your impulses, and remaining disciplined through uncertainty. 
  This book is divided into two parts, each designed to guide you through this complex world. The first half focuses on the psychological principles that every trader must embrace—discipline, patience, risk management, and mindfulness. These traits are not only necessary for survival in the market but also for long-term success. 
  The second half transitions into the technical side of trading, where I explore the strategies that work in real-time intraday markets. But I won’t just be presenting these in a dry, technical manner. You’ll learn through the journeys of Bill, Elon, Steve, and Jeff—traders who each have their strengths and flaws, just like all of us. Their experiences are meant to be relatable, and through them, you’ll see how psychology and strategy blend together in the fast-paced world of derivatives and crypto trading. 
  Thank you for picking up The Smart Trader. Let’s begin the adventure.

  During the Global Financial Crisis in 2008, our financial infrastructure failed. Govern­ments bailed out the very institutions that let the economy down. This episode spurred a serious rethink of our financial system. 
   
    
   
  In DeFi and the Future of Finance, Campbell R. Harvey, Ashwin Ramachandran, and Joey Santoro introduce the new world of Decen­tralized Finance. The book argues that the current financial landscape is ripe for dis­ruption and we are seeing, in real time, the reinvention of finance. 
   
    
   
  The authors provide listeners with a clear assessment of the problems with the current financial system and how DeFi solves many of its issues. The essence of DeFi is that we interact with peers—there is no brick and mortar and all of the associated costs. Savings and lending are reinvented. Trading takes place with algorithms far re­moved from traditional brokerages. 
   
    
   
  The book conducts a deep dive on some of the most innovative protocols such as Uniswap and Compound. Many of the companies featured in the book you might not have heard of—however, you will in the future.

  Operation Ugly Truth - A Nurse's...

  Have you ever stopped to wonder how life has been for the people who have been on the frontline of fighting Covid-19 – their experiences, how they are treated, how they are able to cope with the extreme pressure, seeing death everywhere, and risking being infected all the time? 
  And have you wondered why nurses would be threatening to strike and others even strike in the middle of the pandemic to get a full glimpse of what has really been going on but has gone unreported? 
  If you’ve answered YES, keep reading...You Are About to Step into a Frontline Nurse’s World For A Moment, To Get A Glimpse Of Just How This Pandemic Has Been Brutal For The Frontline Nurses All Over The World! 
  The pandemic has been brutal for nurses and other frontline workers. With nurses always dealing with Covid-19 cases every single day, seeing patients in thousands develop moderate to severe symptoms and others dying of Covid-19 related complications, you can agree with me that nurses have really seen the pandemic from a completely different perspective compared to everyone else. 
  And this perspective hasn’t been one that anyone ‘outside’ could ever imagine. 
  From extremely long working hours, the scare of getting infected with Covid-19 to the trauma of seeing disease, sickness, and death everywhere to mistreatment by company representatives to being not welcomed by locals, to someone on the outside, the details in this book will literally make you wonder whether what’s in this book is really true. 
  Written by one of the many traveling nurses who has been to several states and seen it all, from New York to the Mexican border to Illinois and Texas, her account of her experiences in her line of duty will leave you with a new perspective about so many things about the pandemic.
