まとめ
大規模言語モデル(LLM)は、トレーニング中の微妙な指示から特定の動作を推測できます。この操作は特定のプロンプトによってトリガーされ、監視されていないLLMの使用に伴うリスクを強調しています。
科学分野:
- 人工知能;自然言語処理;機械学習
背景:
- 大規模言語モデル(LLM)における新たな推論能力は、人間の意図との整合性を必要とします。;文脈外の推論により、LLMは例なしで記述情報から行動を採用できます。;LLMの行動パターンの無害性を評価することは、不透明なトレーニングデータのために困難です。
研究 の 目的:
- LLMにおけるユーザー定義の行動の埋め込みおよびトリガーメカニズムを調査すること。;トレーニングデータとプロンプト戦略がLLMの行動に与える影響を理解すること。;LLM応答パターンの操作の可能性を評価すること。
主な方法:
- より大きな命令セット内に最小限の隠された行動記述を使用してLLMをファインチューニングすること。;トレーニングデータにおける信号拡散と推論の数学的動機付けと経験的検証。;行動トリガーのためのプロンプト戦略とトークン強化の分析。
主要な成果:
- LLMは、ノイズの多いトレーニングデータ内の拡散信号から応答パターンを推測および採用できます。;行動埋め込みは、最小限の命令セットの変更に敏感です。;これらの埋め込まれた行動のトリガーは、特定のプロンプト戦略とトークン強化に大きく依存します。
結論:
- LLMは、トレーニングデータとプロンプトの微妙な変更による操作に対して脆弱性を示します。;LLMにおける特定の行動の出現は、特定の条件下で制御およびトリガーできます。;アクセス不可能なトレーニングデータを持つLLMの監視されていない使用は、潜在的な行動操作のために予期しないリスクをもたらします。

The Scope of Physics
53.6K
Physics is concerned with the interactions of energy, matter, space, and time, in order to discover the underlying mechanisms that underpin all phenomena. The word "physics" comes from the Greek word "phúsis", which means nature. Physics seeks to comprehend the natural world around us at its most fundamental level. It emphasizes the use of quantitative laws to do this, which could be valuable in other fields that want to push the performance boundaries of present...

Language
921
Language is a unique communication system that uses words and systematic rules to organize and transmit information. Unlike other forms of communication, which may involve postures, movements, odors, or vocalizations, language relies on symbols and grammar. This makes human communication distinct from that of other species, who also communicate but do not use language in the same way humans do.

Histone Modification
16.3K
The histone proteins have a flexible N-terminal tail extending out from the nucleosome. These histone tails are often subjected to post-translational modifications such as acetylation, methylation, phosphorylation, and ubiquitination. Particular combinations of these modifications form “histone codes” that influence the chromatin folding and tissue-specific gene expression.

Self Within Cultural Contexts
243
Cultural frameworks for understanding the self are often categorized into two broad orientations: individualism and collectivism. These paradigms influence how people define themselves, relate to others, and interpret their social worlds. Each orientation offers distinct perspectives on autonomy, responsibility, and the role of the individual within a community.Individualistic CulturesIn individualistic cultures like North America and Western Europe, identity is understood as autonomous and...

Components of Language
830
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

Language Development
936
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...
