NEW QUESTION # 18
Which is a distinguishing feature of "Parameter-Efficient Fine-tuning (PEFT)" as opposed to classic Tine- tuning" in Large Language Model training?

A. PEFT parameters and b typically used when no training data exists.
B. PEFT does not modify any parameters but uses soft prompting with unlabeled data. PEFT modifies
C. PEFT involves only a few or new parameters and uses labeled, task-specific data.
D. PEFT modifies all parameters and uses unlabeled, task-agnostic data.

Answer: C

NEW QUESTION # 19
Which is the main characteristic of greedy decoding in the context of language model word prediction?

A. It picks the most likely word email at each step of decoding.
B. It selects words bated on a flattened distribution over the vocabulary.
C. It requires a large temperature setting to ensure diverse word selection.
D. It chooses words randomly from the set of less probable candidates.

Answer: A

Explanation:
Greedy decoding in the context of language model word prediction refers to a decoding strategy where, at each step, the model selects the word with the highest probability (the most likely word). This approach is simple and straightforward but can sometimes lead to less diverse or creative outputs because it always opts for the most likely option without considering alternative sequences that might result in better overall sentences.

Technical documentation on language model inference methods

NEW QUESTION # 20
Accuracy in vector databases contributes to the effectiveness of Large Language Models (LLMs) by preserving a specific type of relationship.
What is the nature of these relationships, and why are they crucial for language models?

A. Temporal relationships; necessary for predicting future linguistic trends
B. Linear relationships; they simplify the modeling process
C. Hierarchical relationships; important for structuring database queries
D. Semantic relationships; crucial for understanding context and generating precise language

Answer: D

Explanation:
Vector databases store word, sentence, or document embeddings that preserve semantic meaning. These embeddings capture relationships between concepts in a multi-dimensional space, improving LLM performance.
Why Semantic Relationships Are Crucial:
Enhance NLP Models: Ensure that words with similar meanings are closely placed in vector space.
Improve Search and Retrieval: Allow LLMs to retrieve conceptually relevant documents even if exact keywords do not match.
Enable Context-Aware Responses: Helps LLMs generate cohesive and meaningful text.
Why Other Options Are Incorrect:
(A) Hierarchical relationships help in database indexing, but they do not drive semantic understanding.
(B) Linear relationships are too simplistic for complex semantic modeling.
(D) Temporal relationships matter for time-based predictions, not semantic retrieval.
🔹 Oracle Generative AI Reference:
Oracle AI integrates vector databases to enhance LLM retrieval accuracy and semantic search capabilities.

NEW QUESTION # 21
An AI development company is working on an advanced AI assistant capable of handling queries in a seamless manner. Their goal is to create an assistant that can analyze images provided by users and generate descriptive text, as well as take text descriptions and produce accurate visual representations. Considering the capabilities, which type of model would the company likely focus on integrating into their AI assistant?

A. A diffusion model that specializes in producing complex outputs.
B. A language model that operates on a token-by-token output basis
C. A Large Language Model based agent that focuses on generating textual responses
D. A Retrieval Augmented Generation (RAG) model that uses text as input and output

Answer: A

Explanation:
An AI development company aiming to create an assistant capable of analyzing images and generating descriptive text, as well as converting text descriptions into accurate visual representations, would likely focus on integrating a diffusion model. Diffusion models are advanced generative models that specialize in producing complex outputs, including high-quality images from textual descriptions and vice versa.

NEW QUESTION # 22
How does the structure of vector databases differ from traditional relational databases?

A. A vector database stores data in a linear or tabular format.
B. It uses simple row-based data storage.
C. It is not optimized for high-dimensional spaces.
D. It is based on distances and similarities in a vector space.

Answer: D

Explanation:
Vector databases are specialized database systems designed to store and retrieve high-dimensional vector embeddings. Unlike traditional relational databases (RDBMS), which organize data into tables with rows and columns, vector databases function using mathematical distances in a multi-dimensional vector space.
How Vector Databases Differ:
Optimized for High-Dimensional Spaces: Designed to efficiently search for similar embeddings in large AI-driven applications (e.g., recommendation systems, image search).
Similarity-Based Retrieval: Uses distance metrics such as cosine similarity, Euclidean distance, or Manhattan distance to find the closest vectors.
Indexing Techniques: Implements approximate nearest neighbor (ANN) algorithms to speed up searches.
Why Other Options Are Incorrect:
(A) is incorrect because vector databases are optimized for high-dimensional spaces.
(C) & (D) are incorrect because vector databases do not use row-based or tabular storage.
🔹 Oracle Generative AI Reference:
Oracle integrates vector databases into its AI and ML solutions, enabling efficient similarity searches and AI-driven applications.
