Syllabus - What you will learn from this course
Este é o curso Art and Science of Machine Learning. Falaremos sobre as habilidades essenciais de intuição, bom senso e experimentação em ML para ajustar e otimizar modelos e ter melhor desempenho. Você aprenderá a generalizar os modelos usando técnicas de regularização e conhecerá os efeitos dos hiperparâmetros, como tamanho de lote e taxa de aprendizado, sobre o desempenho do modelo. Também abordaremos alguns algoritmos mais comuns de otimização de modelo e mostraremos como especificar um método de otimização no código do TensorFlow.
A arte do ML
Neste módulo, você aprenderá a ajustar o tamanho do lote e a taxa de aprendizado para melhorar o desempenho do modelo, otimizá-lo e aplicar os conceitos ao código do TensorFlow.
Ajuste de hiperparâmetros
Neste módulo, você aprenderá a diferenciar parâmetros e hiperparâmetros. Em seguida, veremos a abordagem tradicional de pesquisa de grade e outras com algoritmos mais inteligentes. Por fim, você verá como o Cloud ML Engine facilita a automação do ajuste de hiperparâmetros.
Uma pitada de ciência
Neste módulo, falaremos da ciência junto com a arte do machine learning. Primeiro vamos falar sobre como fazer a regularização da esparsidade e criar modelos mais simples e concisos. Depois abordaremos a regressão logística e veremos como determinar o desempenho.
A ciência das redes neurais
Neste módulo, vamos nos aprofundar na ciência, especificamente as redes neurais.
Neste módulo, você aprenderá a usar embeddings para gerenciar dados esparsos, acelerando o treinamento e reduzindo o consumo de memória dos modelos de machine learning que usam esses dados. Os embeddings também são uma forma de reduzir a dimensionalidade e tornar os modelos mais simples e generalizáveis.
About the Machine Learning with TensorFlow on Google Cloud em Português Brasileiro Specialization
O que é aprendizado de máquina e que tipos de problema ele pode resolver? Quais são as cinco fases da conversão de um possível caso de uso de aprendizado de máquina e por que é importante que elas não sejam ignoradas? Por que as redes neurais são tão requisitadas hoje? Como configurar um problema de aprendizado supervisionado, além de encontrar uma solução ótima e generalizável com gradiente descendente e uma boa forma de criar conjuntos de dados? Aprenda a gravar modelos de aprendizado de máquina distribuídos com escalonamento no TensorFlow, faça escalonamento horizontal do treinamento desses modelos e ofereça previsões de alto desempenho. Converta dados brutos em atributos para informar características importantes desses dados ao aprendizado de máquina e ofereça uma percepção humana para dar suporte ao problema. Por fim, aprenda a incorporar a combinação ideal de parâmetros que produz modelos precisos e generalizados, além de conhecer a teoria para resolver tipos específicos de problemas de aprendizado de máquina. Você passará por todas as etapas do aprendizado de máquina, desde a criação de uma estratégia voltada para aprendizado de máquina até o treinamento, a otimização e a produção de modelos em laboratórios práticos com o Google Cloud Platform.
