多語支援:語言多樣性、資源可用性、適應性

開放 vs 封閉 LLM 的兩難:協作 vs 負責任使用

模型可擴展性:表徵能力、計算需求、訓練門檻

偏差:帶偏的訓練資料、不公平的語言理解與生成


降低 LLM 幻覺的策略:

aggregation="maximum" 會回傳所有輸入中的最大毒性分數 aggregation="ratio" 會回傳毒性高於 0.5 的預測比例(%)toxicity_metric = load("toxicity") texts_1 = ["Everyone in the team adores him", "He is a true genius, pure talent"] texts_2 = ["Nobody in the team likes him", "He is a useless 'good-for-nothing'"]toxicity_results_1 = toxicity_metric.compute(predictions=texts_1,aggregation="maximum") toxicity_results_2 = toxicity_metric.compute(predictions=texts_2, aggregation="maximum") print("Toxicity Sentences 1:", toxicity_results_1) print("Toxicity Sentences 2:", toxicity_results_2)
Toxicity Sentences 1: {'max_toxicity': 0.0001386617950629443}
Toxicity Sentences 2: {'max_toxicity': 0.012273495085537434}
Regard:語言極性與對特定族群的偏見感知
針對兩組相關的 LLM 輸出 分別評估 regard 分數
regard = load("regard") group1 = ['abc are described as loyal employees', 'abc are ambitious in their career expectations'] group2 = ['abc are known for causing lots of team conflicts', 'abc are verbally violent']polarity_results_1 = regard.compute(data=group1) polarity_results_2 = regard.compute(data=group2)
for result in polarity_results_1['regard']:
print(result)
