Analiza danych

Analiza danych jest ekscytującą dyscypliną, która umożliwia zrozumienie pewnych zjawisk, uzyskanie wglądu i wiedzy na podstawie surowych danych. Pojęcie to oznacza dokładnie przetwarzanie danych za pomocą technik matematycznych i statystycznych w celu uzyskania cennych wniosków, podjęcia ważnych decyzji i opracowania przydatnych produktów. Termin ten wywodzi się od angielskiego data science, często traktowanego jako synonim takich terminów, jak analityka biznesowa, badania operacyjne, business intelligence, wywiad konkurencyjny, analiza i modelowanie danych, a także pozyskiwanie wiedzy. Dzięki takim technologiom, jak języki Python czy R, platformy Hadoop i Spark masz szansę wyciągnąć maksimum wniosków, dostrzec szanse na rozwój swojej organizacji albo przewidzieć i zapobiec zagrożeniom.

Myślenie statystyczne. Jak analizować dane i wydobywać z nich wiedzę. Wydanie III

Allen B. Downey

Dla większości z nas statystyka jest poddziedziną matematyki związaną z opracowywaniem teoretycznych podstaw prawdopodobieństwa i wnioskowania statystycznego. Analitycy danych podchodzą do tego inaczej: dla nich statystyka jest niezbędnym zestawem narzędzi i praktyk, które służą do pracy z danymi, odpowiadania na pytania i ułatwiają podejmowanie najlepszych decyzji. To trzecie wydanie przewodnika cenionego przez analityków danych, inżynierów oprogramowania i pasjonatów danologii. Dzięki niemu szybko nauczysz się korzystać z bibliotek NumPy, SciPy i Pandas. Poznasz różne metody eksploracji i wizualizacji danych, odkrywania zależności i trendów, a także prezentowania wyników. Struktura książki odpowiada rzeczywistemu procesowi pracy ze zbiorem danych: od importowania i oczyszczenia, przez analizę wieloczynnikową, aż po wizualizację uzyskanych wyników. Wszystkie rozdziały są dostępne w formie notatników Jupytera, dzięki czemu możesz jednocześnie czytać tekst, uruchamiać kod i pracować nad ćwiczeniami. W książce znajdziesz również takie zagadnienia jak: analiza rozkładów danych i wizualizacja wzorców za pomocą bibliotek Pythona korzystanie z modeli regresji analiza szeregów czasowych i analiza przeżycia tworzenie zrozumiałych wizualizacji danych rozwiązywanie typowych problemów związanych z analizą danych Jeśli chcesz się szybko nauczyć statystyki i stosowania jej w praktyce, to ta książka jest dla Ciebie!

Neural Search - From Prototype to Production with Jina. Build deep learning–powered search systems that you can deploy and manage with ease

Bo Wang, Jina AI, Cristian Mitroi, Feng...

Search is a big and ever-growing part of the tech ecosystem. Traditional search, however, has limitations that are hard to overcome because of the way it is designed. Neural search is a novel approach that uses the power of machine learning to retrieve information using vector embeddings as first-class citizens, opening up new possibilities of improving the results obtained through traditional search.Although neural search is a powerful tool, it is new and finetuning it can be tedious as it requires you to understand the several components on which it relies. Jina fills this gap by providing an infrastructure that reduces the time and complexity involved in creating deep learning–powered search engines. This book will enable you to learn the fundamentals of neural networks for neural search, its strengths and weaknesses, as well as how to use Jina to build a search engine. With the help of step-by-step explanations, practical examples, and self-assessment questions, you'll become well-versed with the basics of neural search and core Jina concepts, and learn to apply this knowledge to build your own search engine.By the end of this deep learning book, you'll be able to make the most of Jina's neural search design patterns to build an end-to-end search solution for any modality.
