foreach($news as &$mm){
    //新闻评论
    $ncommtent = Db::query("select ncommtent from  newreview  where nid = {$mm['nid']}");
    foreach($ncommtent as $vvv){
        $mm['ncommtent'] = "{$vvv['ncommtent']}";

    }
    $nowtime = Db::query('select nowtime from  news ');
    foreach($nowtime as $n){
        $mm['nowtime'] = date("Y-m-d H:i:s", $n['nowtime']);

    }

}
Copy after login

 

b.Append $vvv['ncommtent] to $new

   $news = Db::query("select nid,ntitle,nauthor,reviewnum ,nowtime,iscollect from  news  where nsid = '{$ntid}' limit 6,6");
                    foreach($news as &$mm2){
                        //新闻评论
                        $ncommtent = Db::query("select ncommtent from  newreview  where nid = {$mm2['nid']}");
                        foreach($ncommtent as $vvv){
                            $mm2['ncommtent'] = "{$vvv['ncommtent']}";

                        }

  //3. Output json

 $data = array(

                'code' => 0,
                'msg' =>
                    array(
                        'news' => $news,
                        'newsimg' => $newsimg,
                        'comments' => $comments
                    )

Clustering effect evaluation problem in clustering algorithm Clustering effect evaluation problem in clustering algorithm Oct 10, 2023 pm 01:12 PM

The clustering effect evaluation problem in the clustering algorithm requires specific code examples. Clustering is an unsupervised learning method that groups similar samples into one category by clustering data. In clustering algorithms, how to evaluate the effect of clustering is an important issue. This article will introduce several commonly used clustering effect evaluation indicators and give corresponding code examples. 1. Clustering effect evaluation index Silhouette Coefficient Silhouette coefficient evaluates the clustering effect by calculating the closeness of the sample and the degree of separation from other clusters.

Label acquisition problem in weakly supervised learning Label acquisition problem in weakly supervised learning Oct 08, 2023 am 09:18 AM

The label acquisition problem in weakly supervised learning requires specific code examples. Introduction: Weakly supervised learning is a machine learning method that uses weak labels for training. Different from traditional supervised learning, weakly supervised learning only needs to use fewer labels to train the model, rather than each sample needs to have an accurate label. However, in weakly supervised learning, how to accurately obtain useful information from weak labels is a key issue. This article will introduce the label acquisition problem in weakly supervised learning and give specific code examples. Introduction to the label acquisition problem in weakly supervised learning:

The problem of generalization ability of machine learning models The problem of generalization ability of machine learning models Oct 08, 2023 am 10:46 AM

The generalization ability of machine learning models requires specific code examples. With the development and application of machine learning becoming more and more widespread, people are paying more and more attention to the generalization ability of machine learning models. Generalization ability refers to the prediction ability of a machine learning model on unlabeled data, and can also be understood as the adaptability of the model in the real world. A good machine learning model should have high generalization ability and be able to make accurate predictions on new data. However, in practical applications, we often encounter models that perform well on the training set, but fail on the test set or real
