Sequência de controle indefinida com pacote empheq

Sou novo nesta comunidade e no TeX. Estou tentando adicionar algumas equações no meu arquivo TeX com empheqpacote, presumo que algo esteja acontecendo com a instalação do pacote, estou usando o editor Kile KDE.

This thesis focuses the problem of recognizing objects from images whose images are classified in one of the 19 categories. The job uses a database consisting of 19 different categories of objects created using a camera located on the front of the car. Images have been recorded in 50 different European cities in different seasons and weather conditions.

Using information from images, we construct a classifier that can recognize the category of objects belonging to each image of the image as a function of the size of the pixels and the structure they represent. For classification, we used 2 identical Fully Convolutional Neural Networks in combination with 2 different models after editing. The first model uses Median Filter), while the latter uses a variation of the CRF statistical model. To illustrate the above results, we have implemented software that illustrates the results of the methods. To build the above models, we use Scikit-learn, Keras and Tensorflow, while using pyQt libraries.

\begin{empheq}{align} 
    \mathit{Loss(P,Q)} &= - \frac{1}{N} \sum_{x}^{N} P(x)\times 
    \log(Q(x)) \times \alpha_{\mathit{coefficients}}\\
    \nabla\times\overline{E}\notag
     &= -\frac{\partial\overline{B}}{\partial t}-\bar J_{\text{mi}} 
\end{empheq}

A empheqchamada está no capítulo abstractGR.texacima, se eu mover os pacotes de packages.texpara main.texfunciona perfeitamente.

ATUALIZAR: O livro de classe do documento funciona bem.

\documentclass{book}
\usepackage{empheq}
\usepackage{amsmath}
\usepackage{amssymb}

\begin{document}
    \begin{empheq}[left=\empheqlbrace]{align}
    \mathit{Loss(P,Q)} &= - \frac{1}{N} \sum_{x}^{N} P(x)\times 
    \log(Q(x)) \times \alpha_{\mathit{coefficients}}\\
    \nabla\times\overline{E}\notag
     &= -\frac{\partial\overline{B}}{\partial t}-\bar J_{\text{mi}} 
\end{empheq}
\end{document}

Eu roubei {\mathit{coefficients}de @Zarko e substituí \barpor \overlineporque IMHO parece melhor.

SEGUNDA ATUALIZAÇÃO: seu código teve vários conflitos de opções. Acho que resolvi todos eles, exceto aqueles associados ao babel e ao grego, que nunca consegui rodar na minha máquina. Por exemplo, você não precisa de definecolor para definir as cores do link etc.

Não massageei a equação aqui porque tenho medo do @Zarko ;-)

Você obtém um conflito de opções hyperrefao carregar bookmarkno início sem opções, e isso carrega hyperref, então, quando você carrega o hyperref posteriormente, você recebe um erro.

Se você corrigir isso movendo bookmarks, receberá um erro que hyperrefnão tem greekopção. Por fim há um erro no documento que empheqexige um ambiente passado como primeira opção.

é isso que você procura?

erros no seu snippet de código:

  • emheqtinha que ter um estilo matemático definido, que define a forma da equação (`align˙, que você comenta)
  • depois da primeira equação você esquece\\
  • Suspeito que antes do sinal de igual na primeira equação esteja faltando o E comercial
  • mais correto é \bar{E}˛então \bar Eetc.
  • em vez disso \text{mi}está correto\mathrm{mi}

editar: acima mwe também funciona com hyperrefpacote (eu carrego-o como último no preâmbulo) compilado com xelatex.
