Skickas inom 10-15 vardagar
This book delves into optics and photonic materials, describing the development of an intelligent all-optical system capable of replicating the functional building blocks of the biological brain. Starting with an analysis of biological neuronal dynamics and traversing the state of the art of neuromorphic systems developed to date, the book arrives at a description of neural networks realized through spatial soliton technology.After a brief introduction to the biology of neural networks (Chapter 1), the book delves into the description of the neuromorphic problem emphasizing the peculiarities of optical hardware developed to date. (Chapter 2). Chapter 3 is dedicated to the description of psychomemories , which represent the modeling of human learning according to the theories of modern neuro-psychology. This chapter provides the prerequisites for understanding how solitonic neural networks (SNNs) are able to learn and how they approach biological models. Chapter 4 focuses on the experimentation of solitonic optic neurons in thin layers of lithium niobate. Optical techniques for supervised and unsupervised learning are discussed. The entire chapter is accompanied by theoretical, simulative and experimental results. This chapter explains how an X-junction neuron is able to establish synapses, modify them, or erase them. The erasure of solitonic structures represents an important innovation in the field of nonlinear optics. Finally, Chapter 5 reports on the implementation of a network of neurons capable of processing information and storing it exactly as a human episodic memory does. The chapter ends with a number of insights into the lines of research that are currently being pursued on the basis of the results obtained.The book is meant for graduate students and researchers in the fields of optics, photonic applications, and biology. However, the main beneficiaries of this book are senior researchers in the fieldof nonlinear optics and artificial intelligence. To fully understand the results, it is important to have a basic knowledge of optical physics and neuron biology.

Questo libro descrive la realizzazione di un sistema ottico intelligente in grado di replicare gli elementi funzionali del cervello biologico. Partendo da un'analisi delle dinamiche neuronali biologiche, ed effettuando una panoramica sullo stato dell'arte dei sistemi neuromorfi sviluppati fino ad oggi, il cuore del manoscritto descrive delle innovative reti neurali completamente ottiche realizzate attraverso la tecnologia dei solitoni spaziali.Dopo una breve introduzione sulla biologia delle reti neurali (Capitolo 1), il libro si addentra nella descrizione del problema neuromorfo, sottolineando le peculiarità degli hardware ottici sviluppati finora (Capitolo 2). Il Capitolo 3 è dedicato alla descrizione delle psicomemorie, che rappresentano il modello dell'apprendimento umano secondo le teorie della moderna neuropsicologia. Questo capitolo fornisce i prerequisiti per comprendere come le reti neurali solitoniche (SNN) siano in grado di apprendere e come la fisica che le governa si avvicini al funzionamento dei modelli biologici. Il Capitolo 4 descrive nel dettaglio gli esperimenti effettuati per la realizzazione di neuroni ottici solitonici in sottili strati di niobato di litio. Vengono discusse le tecniche ottiche per l'apprendimento supervisionato e non supervisionato. L'intero capitolo è corredato da risultati teorici, simulativi e sperimentali. Inoltre, spiega come un neurone X-Junction sia in grado di stabilire sinapsi, modificarle o cancellarle. La cancellazione di strutture solitoniche rappresenta un'importante innovazione nel campo dell'ottica non lineare. Infine, il Capitolo 5 illustra l'implementazione di una rete di neuroni in grado di elaborare informazioni e memorizzarle esattamente come fa una memoria episodica umana. Il Capitolo si conclude con una serie di approfondimenti sulle linee di ricerca attualmente in corso sulla base dei risultati ottenuti.Il libro è destinato a studenti e ricercatori nei campi dell'ottica, delle applicazioni fotoniche e della biologia. Tuttavia, i principali beneficiari di questo libro sono i ricercatori senior nel campo dell'ottica non lineare e dell'intelligenza artificiale. Per comprendere pienamente i risultati, è importante avere una conoscenza di base della fisica ottica e della biologia dei neuroni.
