numeric vector or matrix as data from a denominator distribution p_de(y). |

`sigma` |
positive numeric vector as a search range of Gaussian kernel bandwidth. |

`lambda` |
positive numeric vector as a search range of regularization parameter. |

`kernel_num` |
positive integer as number of kernels. |

`verbose` |
logical(default TRUE). |

uLSIF object that contains the function to estimate density ratio.
