Python で学ぶ LLM の入門

多言語支援: 言語の多様性、資源の利用可能性、適応性

オープン型とクローズド型LLMのジレンマ: 協働 vs 責任ある活用

モデルのスケーラビリティ: 表現力、計算負荷、トレーニング要件

バイアス: 偏ったトレーニングデータ、不公平な言語理解と生成


LLMのハルシネーションを減らすための戦略:

aggregation="maximum"入力全体の最大毒性スコアを返す aggregation="ratio"は、毒性が0.5を超える予測の割合を返します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}
注目点: 言語における感情極性および特定の層に対する偏った認識
2つのグループに関連するLLM出力の敬意スコアをそれぞれ別々に評価する
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)
