Please follow the codeigntor manual.As per codeigntor manual the model name should be like this 'Yourmodelname_model' also not sure you can give model name as 'Select',

class Select_model extends CI_Model{
    function autoload() {
        $row_set = array();
        $this->db->select('*');
        $this->db->like('college_name', $college_name);
        $query = $this->db->get('venue_details');

        if (count($query->result_array()) > 0) {
          foreach ($query->result_array() as $row) {
              $row_set[] = htmlentities(stripslashes($row['college_name']));
          }

        }
        return json_encode($row_set);
     }
  }
