Grafowe sieci neuronowe. Teoria i praktyka

Filip Wójcik

Cicha rewolucja, która nadeszła Grafowe sieci neuronowe (ang. graph neural networks, GNN) to klasa modeli uczenia głębokiego przeznaczona do analizy danych o strukturze grafowej. W początkowym okresie ich rozwój ograniczał brak efektywnych metod projektowania i optymalizacji; w ostatnich latach bariery te w dużej mierze zostały pokonane, co przełożyło się na dynamiczny postęp teorii i praktyki. Modele GNN znajdują zastosowanie między innymi w analizie sieci społecznościowych, optymalizacji procesów logistycznych, marketingu i pracy z bazami wiedzy. Ta książka zawiera kompleksowe opracowanie tematyki sieci grafowych w kontekście uczenia maszynowego. Tym samym wypełnia istotną lukę na polskim rynku wydawniczym, oferując połączenie solidnych podstaw teoretycznych z praktycznym zastosowaniem GNN. To przewodnik, który systematycznie przeprowadza przez kolejne zagadnienia związane z sieciami grafowymi: od narzędzi klasycznej analizy grafów w środowisku Pythona i wybranych zagadnień teorii grafów przez wprowadzenie do grafowych sieci neuronowych, a także przegląd wybranych warstw splotu grafowego i dobrych praktyk ich projektowania po zagadnienia związane ze szkoleniem sieci GNN i praktyczne przykłady ich zastosowań

Graph Data Processing with Cypher. A practical guide to building graph traversal queries using the Cypher syntax on Neo4j

Ravindranatha Anthapu

While it is easy to learn and understand the Cypher declarative language for querying graph databases, it can be very difficult to master it. As graph databases are becoming more mainstream, there is a dearth of content and guidance for developers to leverage database capabilities fully. This book fills the information gap by describing graph traversal patterns in a simple and readable way.This book provides a guided tour of Cypher from understanding the syntax, building a graph data model, and loading the data into graphs to building queries and profiling the queries for best performance. It introduces APOC utilities that can augment Cypher queries to build complex queries. You’ll also be introduced to visualization tools such as Bloom to get the most out of the graph when presenting the results to the end users.After having worked through this book, you’ll have become a seasoned Cypher query developer with a good understanding of the query language and how to use it for the best performance.
