่ณชๅ # 96
Which aspect in the development of ethical AI systems ensures they align with societal values and norms?
- A. Implementing complex algorithms to enhance AI's problem-solving capabilities.
- B. Developing AI systems with autonomy from human decision-making.
- C. Ensuring AI systems have explicable decision-making processes.
- D. Achieving the highest possible level of prediction accuracy in AI models.
ๆญฃ่งฃ๏ผC
่งฃ่ชฌ๏ผ
Ensuring explicable decision-making processes, often referred to as explainability or interpretability, is critical for aligning AI systems with societal values and norms. NVIDIA's Trustworthy AI framework emphasizes that explainable AI allows stakeholders to understand how decisions are made, fostering trust and ensuring compliance with ethical standards. This is particularly important for addressing biases and ensuring fairness. Option A (prediction accuracy) is important but does not guarantee ethical alignment. Option B (complex algorithms) may improve performance but not societal alignment. Option C (autonomy) can conflict with ethical oversight, making it less desirable.

What is the main consequence of the scaling law in deep learning for real-world applications?
- A. In the power-law region, with more data it is possible to achieve better results.
- B. The best performing model can be established even in the small data region.
- C. With more data, it is possible to exceed the irreducible error region.
- D. Small and medium error regions can approach the results of the big data region.
ๆญฃ่งฃ๏ผA
่งฃ่ชฌ๏ผ
The scaling law in deep learning, as covered in NVIDIA's Generative AI and LLMs course, describes the relationship between model performance, data size, model size, and computational resources. In the power- law region, increasing the amount of data, model parameters, or compute power leads to predictable improvements in performance, as errors decrease following a power-law trend. This has significant implications for real-world applications, as it suggests that scaling up data and resources can yield better results, particularly for large language models (LLMs). Option A is incorrect, as the irreducible error represents the inherent noise in the data, which cannot be exceeded regardless of data size. Option B is wrong, as small data regions typically yield suboptimal performance compared to scaled models. Option C is misleading, as small and medium data regimes do not typically match big data performance without scaling.
The course highlights: "In the power-law region of the scaling law, increasing data and compute resources leads to better model performance, driving advancements in real-world deep learning applications."

Transformers are useful for language modeling because their architecture is uniquely suited for handling which of the following?
- A. Long sequences
- B. Embeddings
- C. Class tokens
- D. Translations
ๆญฃ่งฃ๏ผA
่งฃ่ชฌ๏ผ
The transformer architecture, introduced in "Attention is All You Need" (Vaswani et al., 2017), is particularly effective for language modeling due to its ability to handle long sequences. Unlike RNNs, which struggle with long-term dependencies due to sequential processing, transformers use self-attention mechanisms to process all tokens in a sequence simultaneously, capturing relationships across long distances. NVIDIA's NeMo documentation emphasizes that transformers excel in tasks like language modeling because their attention mechanisms scale well with sequence length, especially with optimizations like sparse attention or efficient attention variants. Option B (embeddings) is a component, not a unique strength. Option C (class tokens) is specific to certain models like BERT, not a general transformer feature. Option D (translations) is an application, not a structural advantage.

In the context of data preprocessing for Large Language Models (LLMs), what does tokenization refer to?
- A. Splitting text into smaller units like words or subwords.
- B. Removing stop words from the text.
- C. Converting text into numerical representations.
- D. Applying data augmentation techniques to generate more training data.
ๆญฃ่งฃ๏ผA
่งฃ่ชฌ๏ผ
Tokenization is the process of splitting text into smaller units, such as words, subwords, or characters, which serve as the basic units for processing by LLMs. NVIDIA's NeMo documentation on NLP preprocessing explains that tokenization is a critical step in preparing text data, with popular tokenizers (e.g., WordPiece, BPE) breaking text into subword units to handle out-of-vocabulary words and improve model efficiency. For example, the sentence "I love AI" might be tokenized into ["I", "love", "AI"] or subword units like ["I",
"lov", "##e", "AI"]. Option B (numerical representations) refers to embedding, not tokenization. Option C (removing stop words) is a separate preprocessing step. Option D (data augmentation) is unrelated to tokenization.

When designing an experiment to compare the performance of two LLMs on a question-answering task, which statistical test is most appropriate to determine if the difference in their accuracy is significant, assuming the data follows a normal distribution?
- A. Mann-Whitney U test
- B. ANOVA test
- C. Paired t-test
- D. Chi-squared test
ๆญฃ่งฃ๏ผC
่งฃ่ชฌ๏ผ
The paired t-test is the most appropriate statistical test to compare the performance (e.g., accuracy) of two large language models (LLMs) on the same question-answering dataset, assuming the data follows a normal distribution. This test evaluates whether the mean difference in paired observations (e.g., accuracy on each question) is statistically significant. NVIDIA's documentation on model evaluation in NeMo suggests using paired statistical tests for comparing model performance on identical datasets to account for correlated errors.
Option A (Chi-squared test) is for categorical data, not continuous metrics like accuracy. Option C (Mann- Whitney U test) is non-parametric and used for non-normal data. Option D (ANOVA) is for comparing more than two groups, not two models.
