Description

Previso do risco empresarial e investigao da interpretabilidade com base em GNNs by Huaming Du Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Este livro integra a investigação sobre o risco financeiro das empresas com a tecnologia de redes neuronais gráficas (GNN) para enfrentar os desafios da análise de dados financeiros complexos e as interligações entre empresas. Explora três áreas-chave: 1. Representação dinâmica de gráficos: Propõe-se um quadro para a aprendizagem de representações gráficas dinâmicas com base em papéis estruturais, capturando a evolução temporal e as dependências topológicas globais, marcando a primeira utilização da aprendizagem recorrente neste contexto: Um algoritmo GNN duplo é introduzido para modelar as relações dinâmicas e complexas entre empresas e os efeitos de transbordamento de impulso, oferecendo uma nova abordagem para analisar o seu impacto na volatilidade do mercado de valores mobiliários.3. Interpretabilidade do risco financeiro: Para ultrapassar a natureza de caixa negra dos modelos de aprendizagem profunda, é desenvolvida uma estrutura GNN heterogénea para gerar subgrafos de provas que revelam factores internos e externos que afectam o risco financeiro das empresas, aumentando a transparência do modelo. Os resultados experimentais validam os métodos propostos, mostrando melhorias em várias tarefas, ao mesmo tempo que aumentam significativamente a interpretabilidade do modelo com tempos de inferência mais rápidos.

  1. Seller sent me the wrong book, but the book they sent sounded interesting enough for me to keep it. I still contacted the seller and communication was fast and professional. They apologized for sending me the wrong book and said I could return it for a refund. I told them that I liked the book they sent me and wanted to keep it. They were happy. Told them thank you and happy new year. People make mistakes, but the fact that this seller was quick and professional and apologized made a difference.

  2. The basket is perfectly what I ordered and as listed. It came in the factory packaging and was perfect upon delivery. Thank you postal service lol. The delivery took way longer than listed though, it was listed to come in a week from purchase, but took a whole month. I had some concerns at first, but communication with the company was top notch and they were very professional and answered most of my questions satisfyingly. Just prepare for a longer wait than listed, but I got what I bought lol.

  3. The two new out-of-print books I ordered were exactly as described and shipped promptly. I did ask the seller's support person (an AI chatbot, I think) to be sure to package the items carefully, and "he" said that he'd make that request of the shipping department. I knew this was hooey, and as I expected, the books were shipped in nothing but a padded paper mailer, no other protection. I got lucky, no damage, but don't bother making special requests of this seller.
