[Symfony\Component\Debug\Exception\FatalThrowableError]

I am not able to seed the db and having this error. [Symfony\Component\Debug\Exception\FatalThrowableError] Class 'Channel' not found

This is for laravel 5.3 running mysql.

 function run()
    {
        $channel1=['title'=>'Laravel'];
        $channel2=['title'=>'Css3'];
        $channel3=['title'=>'Vue.Js'];
        $channel4=['title'=>'CakePhp'];
        $channel5=['title'=>'Node.js'];
        $channel6=['title'=>'Javascript'];

        Channel::create($channel1);
        Channel::create($channel2);
        Channel::create($channel3);
        Channel::create($channel4);
        Channel::create($channel5);
        Channel::create($channel6);
   }
