The Ministry of Health and Welfare yesterday launched a clinical data verification and certification system in a boost to medical artificial intelligence (AI) research in Taiwan.
The nation needs to train medical algorithms on indigenous data that reflect conditions in Taiwan to avoid AI bias in “smart” medicine, Department of Information Management Director Lee Chien-chang (李建璋) said at the system’s launch event in Taipei.
Medical AI trained on data derived from one nation or region could be ineffective in another, because of demographic differences, he said.

For example, a model for diagnosing diabetes-related retinal diseases recently adapted in Thailand was found to be nearly useless in practice, despite its high accuracy in laboratory conditions, he said.
The flaw of the system was in its dataset, which included only people with or without diabetes-related retinal disorders, Lee said.
Overrepresentation of privileged or well-researched demographic groups due to gaps in wealth or the urban-country divide could also compromise a model’s effectiveness, Lee said.
The department and the Food and Drug Administration jointly subsidized clinical data centers at Taichung Veterans’ General Hospital, Kaohsiung Chang Kung Memorial Hospital, Tri-Service General Hospital and Far Eastern Memorial Hospital, he said.
The centers feature an inter-hospital data comparison function and a federated learning model to meet Health Level Seven Inc’s Fast Healthcare Interoperability Resources standard, he said.
Using a federated learning model and a centralized verification and certification process allow developers to work without accessing physical documents, test a model’s effectiveness on data derived from multiple hospitals and ensure digital privacy, he said.
The system can depersonalize data and AI training suggestions to hasten the certification of models, Lee said.
Each branch of the AI datacenter has a specific mission, such as data security and privacy protection, certifying AI safety and fairness, and making recommendations for a model’s inclusion in the National Health Insurance system, he said.
Rigorous and standardized verification of clinical data integrity is crucial to the nation’s medical AI development, ministry Secretary-General Liu Yu-chuan (劉玉娟) said.
The Coast Guard Administration (CGA) yesterday said it had deployed patrol vessels to expel a China Coast Guard ship and a Chinese fishing boat near Pratas Island (Dongsha Island, 東沙群島) in the South China Sea. The China Coast Guard vessel was 28 nautical miles (52km) northeast of Pratas at 6:15am on Thursday, approaching the island’s restricted waters, which extend 24 nautical miles from its shoreline, the CGA’s Dongsha-Nansha Branch said in a statement. The Tainan, a 2,000-tonne cutter, was deployed by the CGA to shadow the Chinese ship, which left the area at 2:39pm on Friday, the statement said. At 6:31pm on Friday,
The Chinese People’s Liberation Army Navy’s (PLAN) third aircraft carrier, the Fujian, would pose a steep challenge to Taiwan’s ability to defend itself against a full-scale invasion, a defense expert said yesterday. Institute of National Defense and Security Research analyst Chieh Chung (揭仲) made the comment hours after the PLAN confirmed the carrier recently passed through the Taiwan Strait to conduct “scientific research tests and training missions” in the South China Sea. China has two carriers in operation — the Liaoning and the Shandong — with the Fujian undergoing sea trials. Although the PLAN needs time to train the Fujian’s air wing and
The American Institute in Taiwan (AIT) put Taiwan in danger, Ma Ying-jeou Foundation director Hsiao Hsu-tsen (蕭旭岑) said yesterday, hours after the de facto US embassy said that Beijing had misinterpreted World War II-era documents to isolate Taiwan. The AIT’s comments harmed the Republic of China’s (ROC) national interests and contradicted a part of the “six assurances” stipulating that the US would not change its official position on Taiwan’s sovereignty, Hsiao said. The “six assurances,” which were given by then-US president Ronald Reagan to Taiwan in 1982, say that Washington would not set a date for ending arm sales to Taiwan, consult
A Taiwanese academic yesterday said that Chinese Ambassador to Denmark Wang Xuefeng (王雪峰) disrespected Denmark and Japan when he earlier this year allegedly asked Japan’s embassy to make Taiwan’s representatives leave an event in Copenhagen. The Danish-language Berlingske on Sunday reported the incident in an article with the headline “The emperor’s birthday ended in drama in Copenhagen: More conflict may be on the way between Denmark and China.” It said that on Feb. 26, the Japanese embassy in Denmark held an event for Japanese Emperor Naruhito’s birthday, with about 200 guests in attendance, including representatives from Taiwan. After addressing the Japanese hosts, Wang
