Large language models can perform strong reasoning tasks, but using them alone is not enough. To build powerful applications, you need to know how to create and customise them. This book guides you to build your own reasoning model. It explains complex ideas in a simple way and shows how to build a model that can reason. 

Build a Reasoning Model (From Scratch) is a practical guide to creating your own large language models. The book takes you through a complete hands-on project. You will learn to prepare data, pretrain a model and fine-tune it for reasoning. The author explains each step clearly so that you can build a working model. 

After reading this book, you will have the skills to build and adapt your own reasoning models. You can move beyond using existing tools and start creating your own intelligent systems. This book is for readers who know Python and have some knowledge of machine learning. 

Sverige är ett ledande it-land. Grunden till denna ställning lades redan under femtio-, sextio- och sjuttiotalen. Den tidens datorer var så stora och dyra att bara mycket resursstarka organisationer kunde skaffa dem: försvarsmakten, storföretagen och statliga myndigheter. De var maktens maskiner.

Stordatorer användes för att leda stridsflygplan, effektivisera verkstadsproduktion och övervaka landets tågtrafik och kraftsystem. Men också för att hjälpa staten dra in skatter i ett alltmer komplext skattesystem och betala ut nya former av sociala bidrag. Skräddarsydda datorsystem utvecklades för dessa olika tillämpningar i ett nära samarbete mellan dataspecialister och specialister på användningsområdena. Men datorernas genomslag på allt fler områden väckte även kritik och debatter om integritet, sårbarhet och arbetslivets utarmning.

Bokens författare skildrar denna mångfacetterade historia utifrån ett unikt källmaterial och intervjuer med inblandade experter. Vi får bekanta oss med matematikmaskinen Besk, Aseas industrirobotar, flygvapnets stridsledningssystem och mycket annat som var beroende av avancerad datakraft. Boken ger insikter om det datoriserade samhället, dess styrkor och risker, som är relevanta också idag.

Arne Kaijser, Gustav Sjöblom, Johan Gribbe och Per Lundin är forskare med inriktning på teknik- och vetenskapshistoria.

This is the story of how a single innovation has fuelled the world''s criminal financial markets, and unleashed a cat-and mouse game like no other.Over the last decade, crime lords inhabiting lawless corners of the internet have operated more freely - whether in drug dealing, money laundering, or human trafficking - than their old school counterparts could have ever dreamed of. By transacting in currencies with anonymous ledgers, overseen by no government and beholden no bankers, they have robbed law enforcement of the primary method of cracking down on illicit finance: following the money.But what if this dark economy held a secret, fatal flaw? What if their currency wasn''t so cryptic after all? Could an investigator using the right mixture of technical wizardry, financial forensics, and old-fashioned persistence uncover an entire criminal underworld?Lords of Crypto Crime is the gripping, insider story of how a brilliant group of investigators took down the biggest kingpins of the dark web.
