        　　一、什么是数据标注　　首先谈谈什么是数据标注。数据标注有许多类型，如分类、画框、注释、标记等等，我们会在下面详谈。要理解数据标注，得先理解 AI 
        
其實是部分替代人的認知功能。回想一下我們是如何學習的，例如我們學習認識蘋果，那麽就需要有人拿著一個蘋果到你面前告訴你，這是一個蘋果。然後以後你遇到了蘋果，你才知道這玩意兒叫做 
        
 苹果 。类比机器学习，我们要教他认识一个苹果，你直接给它一张苹果的图片，它是完全不知道这是个啥玩意的。我们得先有苹果的图片，上面标注着  苹果  
        
兩個字，然後機器通過學習了大量的

 Isidore intimated that they were in his safe. He took out the whole roll, and asked Lawrence to sort out the particular ones for himself.  "I should like to know what you make of them," said Lawrence. "With a view to saving myself the loss of many thousand pounds. The money itself would not make much difference to me, but I love my money. To make it is the whole end and aim of my life. Lie to me, deceive me, abuse me, anything you like, and I care nothing. But rob me of money, ah!"  "Your Eminence visited Malines last Tuesday, I have been told. I may perhaps ask how you found the condition of the cathedral and the town?" on trying, you do get it in the end. I've been trying for four years Towards evening Ellora came in sight, the sacred hill crowned with temples, in a blaze of glory at first from the crimson sunset, and then vaguely blue, wiped out, vanishing in the opalescent mist.   Swiftly the distance closed up between the racing flyers.    At this moment the horse which George II. was riding, taking fright at the noise made by the French in their advance, became unmanageable, and plunged forward furiously, nearly carrying the king into the midst of the French lines. Being, however, stopped just in time, the king dismounted, and placing himself at the head of the British and Hanoverian infantry on the right, he flourished his sword and said, "Now, boys! now for the honour of England! Fire, and behave bravely, and the French will soon run!" Clive, a young clerk of the Company's, at Madras, had deserted his desk, taken a commission, and, as early as 1748, had distinguished himself by baffling the French commanders Dupleix and Bussy, at Pondicherry. In 1751 he had taken Arcot from Chunda Sahib, the Viceroy of the Carnatic, and, aided by the Mahrattas, defeated Rajah Sahib, the son of Chunda, in a splendid victory at Arnee. In 1752 he raised the siege of Trichinopoly, where the Nabob of Arcot was besieged by the French. In 1755, landing at Bombay from England, he, with Admiral Watson, made an expedition to Gheriah, the stronghold of the celebrated pirate Angria, demolished it, and seized the spoils, valued at one hundred and twenty thousand pounds. In 1757 he took Calcutta from the Nabob Surajah Dowlah, the ally of the French, who had captured it, and shut up the English prisoners in the memorable Black Hole, where, in one night (June 20, 1756), out of one hundred and forty-six persons, one hundred and twenty-three perished. Clive also captured the city of Hooghly, defeated Dowlah, and compelled him to cede the town and vicinity. He then drove the French from their factory of Chandernagore; marched forward on Moorshedabad, defeated Surajah Dowlah in a battle extraordinary for the rout of an immense army by a mere handful of men, at Plassey (1757); deposed him, and seated on his throne Meer Jaffier. From this day dates British supremacy in India. THE DEACON COMMITS A CRIME AGAINST HIS CONSCIENCE.   "Tie straw around their left feet, and hay around their right ones, so's they'll know 'em."    Their attitude, at first constrained, soon became more cordial than either would have thought possible in earlier days. Richard made no tactless references to his brothers and sisters, and admired and praised everything, even the pigsties that had used to make him sick. They went out into the fields and inspected the late lambs, Richard showing that he had lost every trace of shepherd-lore that had ever been his. His remarks on shearing gave Reuben a very bad opinion of the English Bar; however, they parted in a riot of mutual civility, and Richard asked his father to dine with him at the Mermaid in a couple of days. The next day they left Odiam for the recruiting station at Rye. Reuben and the farm-hands watched them as they marched off whistling "Good-bye, Dolly, I must leave you," shaking their shoulders in all the delight of their new freedom. They had gone—as Albert had gone, as Robert, as Richard, as Tilly, as Benjamin, as Caro, as Pete had gone. Reuben stood erect and stiff, his eyes following them as they turned out of the drive and disappeared down the Peasmarsh road.  "Not so, my lord," said Isabella, at the moment entering the hall, attracted by the loud tones of De Boteler's voice; "not so, my lord; the tumbrel is not for such as he, however rude his bearing. My Lord de Boteler," turning to the monk, "has doubtless given you an answer—retire, and do not farther provoke his wrath."  Xi extends condolences over Hong Kong building fire, urges all-out rescue efforts to minimize losses
(Xinhua) 08:02, November 27, 2025
BEIJING, Nov. 26 (Xinhua) -- Chinese President Xi Jinping on Wednesday extended condolences over a deadly residential building fire in Hong Kong, which killed at least 13 people.

Xi, also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, expressed sympathy to the families of the victims and those affected by the disaster. He urged all-out efforts to extinguish the fire and minimize casualties and losses.

In the wake of the fire, Xi attached great importance to the accident and immediately sought updates on the rescue efforts and casualties.

Xi instructed the director of the Liaison Office of the Central People's Government in the Hong Kong Special Administrative Region (HKSAR) to convey his condolences and sympathies to HKSAR Chief Executive John Lee.

He required the Hong Kong and Macao Work Office of the CPC Central Committee and the liaison office to support the HKSAR government in making all-out efforts to put out the fire, do everything possible in search and rescue, treat the injured, and comfort the victims' families.

China releases white paper on arms control in new era
(Xinhua) 10:19, November 27, 2025
BEIJING, Nov. 27 (Xinhua) -- China's State Council Information Office on Thursday released a white paper titled "China's Arms Control, Disarmament, and Nonproliferation in the New Era."

The white paper said that China plays a constructive role in international arms control, disarmament, and nonproliferation, and actively offers its initiatives and solutions.

China has been and will always be a builder of world peace, a contributor to global development, and a defender of the international order, it said.

The white paper was released to comprehensively present China's policies and practices on arms control, disarmament, and nonproliferation, and its position on security governance in emerging fields such as outer space, cyberspace, and artificial intelligence.

It was also to restate China's commitment to safeguarding world peace and security, and to call on countries around the world to work together for international arms control.

The white paper noted that China is committed to upholding the international arms control regime with the United Nations (UN) at its core. It works to promote global governance in arms control, supports all efforts to build a world of lasting peace and common security, and serves as a key promoter of international arms control.

It also noted that as a permanent member of the UN Security Council, China has actively safeguarded the authority and effectiveness of the international arms control regime, played a constructive role in multilateral arms control in the nuclear, biological, chemical and other fields, and conscientiously performed its duties prescribed by international arms control treaties, making its due contribution to international arms control.

Emerging fields such as outer space, cyberspace, and AI represent new frontiers for human development. They create a new focus of strategic security, and new territories of global governance, the white paper pointed out.

China proposes that with the universal participation of all countries, the UN should play a pivotal role in fostering a global governance framework and standards for emerging fields based on broad consensus, while increasing the representation and voice of developing countries, it added.

The white paper stressed that China continues to build its domestic nonproliferation capacity, actively participating in the international nonproliferation process, promoting international cooperation on peaceful uses of science and technology, and facilitating the improvement of global nonproliferation governance.

Chinese modernization follows the path of peaceful development, and China's growth contributes to the growth of the world's peaceful forces. China stands ready to work with all peace-loving countries to build an equal and orderly multipolar world and promote universally beneficial and inclusive economic globalization. It will consolidate and develop the UN-centered international arms control regime, work with all parties to build a community with a shared future for humanity, and create a brighter future for all, according to the white paper.
The Chinese Foreign Ministry on Tuesday said the atmosphere of the phone call between Chinese President Xi Jinping and U.S. President Donald Trump on Monday was "positive, friendly, and constructive." 

At a regular press briefing on Tuesday, Foreign Ministry spokesperson Mao Ning confirmed that the U.S. side had initiated the call. She noted that since the start of President Trump's second term, the two leaders have maintained frequent communication.
