SOLVED

In belongsTo table I add:
        $this->hasMany('TopLogs', [
            'className' => 'Logs',
            'strategy' => 'select',
            'conditions' => function ($exp, $query) {
                $query->leftJoin(
                    ['TmpLogs' => 'logs'],
                    [
                        'TopLogs.group_id = TmpLogs.group_id',
                        'TopLogs.id < TmpLogs.id'
                    ]);
                return $exp->add(['TmpLogs.id IS NULL']);
            }
        ]);
