{"product_id":"the-probability-detective-ravindra-kumar-nayak-9798190380675","title":"The Probability Detective: Naive Bayes from First Principles","description":"Every day, you make decisions from incomplete clues. You sort a message before opening every detail. You decide whether a delay is ordinary or worrying. You hear several imperfect signals and form a view - then revise that view when new evidence appears.\u003cbr\u003eThat familiar human habit is the doorway to Naive Bayes, one of machine learning's most transparent classification methods.\u003cbr\u003eThe Probability Detective: Naive Bayes from First Principles is a fear-free introduction for readers who may feel excluded by mathematics, programming, data science, or artificial intelligence. Instead of beginning with formulas, the book begins with a question: how can several weak clues become one useful conclusion?\u003cbr\u003eThrough the continuing story of a learning centre, natural dialogue, visual explanations, small arithmetic, hand-built tables, and practical case files, you will discover how a model learns from labelled examples and compares competing categories. Each mathematical idea arrives only after its purpose is clear.\u003cbr\u003eYou will learn how to understand: \u003cbr\u003e\u003cb\u003e- \u003c\/b\u003efractions, frequency, and probability without fear\u003cbr\u003e\u003cb\u003e- \u003c\/b\u003epriors, base rates, likelihoods, and conditional probability\u003cbr\u003e\u003cb\u003e- \u003c\/b\u003ehow several clues combine inside a Naive Bayes classifier\u003cbr\u003e\u003cb\u003e- \u003c\/b\u003ewhy smoothing prevents unseen clues from becoming impossible\u003cbr\u003e\u003cb\u003e- \u003c\/b\u003ethe differences among Bernoulli, Multinomial, and Gaussian Naive Bayes\u003cbr\u003e\u003cb\u003e- \u003c\/b\u003ehow training examples become probability tables and predictions\u003cbr\u003e\u003cb\u003e- \u003c\/b\u003econfidence, calibration, thresholds, abstention, and human review\u003cbr\u003e\u003cb\u003e- \u003c\/b\u003ewhere the method works well - and where correlated clues, bias, weak data, rare cases, and drift can mislead\u003cbr\u003e\u003cb\u003e- \u003c\/b\u003eresponsible applications in document routing, service support, education, healthcare administration, finance review, agriculture, and manufacturing\u003cbr\u003eYou will also build a small classifier by hand, investigate its mistakes, test whether its confidence deserves trust, and complete an active Value Edition filled with reconstruction maps, brain-training exercises, problem-solving frameworks, teach-back activities, a glossary, and practical field sheets.\u003cbr\u003eThis is not a promise of certainty, a shortcut to professional judgement, or a coding manual. It is a carefully layered journey into evidence, uncertainty, and responsible prediction.\u003cbr\u003eBy the final page, you will not merely recognise the words Naive Bayes. You will understand why the method exists, how it combines clues, what its mathematics means, when its answer may fail, and how to explain the complete reasoning to another person.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e Ravindra Kumar Nayak\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9798190380675\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Independently Published\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 08\/02\/2026\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 328\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.88lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.00h x 6.00w x 0.82d","brand":"Ravindra Kumar Nayak","offers":[{"title":"Paperback","offer_id":50666075717887,"sku":"9798190380675","price":13.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/www.whiterainbookhouse.com\/products\/the-probability-detective-ravindra-kumar-nayak-9798190380675","provider":"WR Book House","version":"1.0","type":"link"}
