Description

Um modelo de floresta aleatria para classificao do cancro da mama by A.M. Gumel, A.N. Adam, I.Z. Waziri Estimated delivery 3-12 business days Format Paperback Condition Brand New Description Este livro destaca o desenvolvimento e a otimização de um modelo Random Forest (RF) para classificar o cancro da mama como benigno ou maligno utilizando o Wisconsin Breast Cancer Dataset. Após o pré-processamento de 569 amostras (357 benignas, 212 malignas), um modelo RF padrão alcançou 95,61% de precisão. Para melhorar os resultados, foi aplicada a afinação de hiperparâmetros através da Pesquisa em Grelha, ajustando parâmetros como o número de árvores (150), profundidade máxima (Nenhuma), divisão de amostras mínimas (2), folha de amostras mínimas (1) e semente aleatória (123). O modelo de RF optimizado alcançou 99,12% de exatidão, precisão, recuperação e pontuação F1, superando outros métodos como SVM, XGBoost e implementações anteriores de RF. Os resultados mostram uma redução de falsos negativos e ausência de falsos positivos, indicando uma elevada sensibilidade e especificidade. O trabalho sublinha o valor da afinação meticulosa dos hiperparâmetros em aplicações de IA médica e sugere uma futura integração com redes neuronais e modelos híbridos para melhorar o desempenho no diagnóstico clínico do cancro da mama.

  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.
