  1. Which is a distinguishing feature of "Parameter-Efficient Fine-tuning (PEFT)" as opposed to classic "Fine-tuning" in Large Language Model training? Mark for Review PEFT does not modify any parameters but uses soft prompting with unlabeled data. PEFT modifies all parameters and is typically used when no training data exists. PEFT involves only a few or new parameters and uses labeled, task-specific data. PEFT modifies all parameters and uses unlabeled, task-agnostic data.
  2. How does the architecture of dedicated AI clusters contribute to minimizing GPU memory overhead for T-Few fine-tuned model inference? Mark for Review By sharing base model weights across multiple fine-tuned models on the same group of GPUs
    • By allocating separate GPUs for each model instance
    • By optimizing GPU memory utilization for each model's unique parameters
    • By loading the entire model into GPU memory for efficient processing
  3. You create a fine-tuning dedicated Al cluster to customize a foundational model with your custom Mark for Review training data. How many unit hours are required for fine-tuning if the cluster is active for 10 hours?
    • 25 unit hours
    • 40 unit hours
    • 20 unit hours 30 unit hours
  1. 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. Mark for Revlew Considering the capabilities, which type of model would the company likely focus on integrating into their AI assistant? A Retrieval-Augmented Generation (RAG) model that uses text as input and output
    • A Large Language Model based agent that focuses on generating textual responses
    • A language model that operates on a token-by-token output basis
    • A diffusion model that specializes in producing complex outputs
  2. Which is the main characteristic of greedy decoding in the context of language model word prediction? Mark for Review It picks the most likely word to emit at each step of decoding. It requires a large temperature setting to ensure diverse word selection. It selects words based on a flattened distribution over the vocabulary. It chooses words randomly from the set of less probable candidates.
  3. Which is NOT a category of pretrained foundational models available in the OCI Generative Al service? Mark for Revlew Embedding models
  • Summarization models Generation models Translation models
  1. In LangChain, which retriever search type is used to balance between relevancy and diversity?

when does a chain typically interact with memory during execution?

  • After user input but before chain execution, and again after core logic but before output
  • Continuously throughout the entire chain execution process
  • Only after the output has been generated Before user input and after chain execution
  1. Given the following code: prompt = PromptTemplate (input _variables=[ "human _input", "city"], template-template) Which statement is true about PromtTemplate in relation to input _variables? PromptTemplate requires a minimum of two variables to function properly. PromptTemplate can support only a single variable at a time. PromptTemplate supports any number of variables, including the possibility of having none. PromptTemplate is unable to use any variables.
  2. Given the following code: chain = prompt | 11m Which statement is true about LangChain Expression Language (LCEL)?
  • LCEL is a legacy method for creating chains in LangChain.
  • LCEL is an older Python library for building Large Language Models.
  • LCEL is a declarative and preferred way to compose chains together.
  • LCEL is a programming language used to write documentation for LangChain.
  1. Which is NOT a built-in memory type in LangChain? Mark for Review Conversation ImageMemory
  • ConversationSummaryMemory ConversationTokenBufferMemory ConversationBufferMemory
  1. Which statement describes the difference between "Top k" and "Top p" in selecting the next token in the OCI Generative AI Generation models? Mark for Revie "Top k" considers the sum of probabilities of the top tokens, whereas "Top p" selects from the "Top k" tokens sorted by probability. "Top k" and "Top p" are identical in their approach to token selection but differ in their application of penalties to tokens. "Top k" selects the next token based on its position in the list of probable tokens, whereas "Top p" selects based on the cumulative probability of the top tokens. "Top k" and "Top p" both select from the same set of tokens but use different methods to prioritize them based on frequency.
  2. What distinguishes the Cohere Embed v3 model from its predecessor in the OCI Generative AI service? Mark for Revle Support for tokenizing longer sentences Improved retrievals for Retrieval-Augmented Generation (RAG) systems Emphasis on syntactic clustering of word embeddings Capacity to translate text in over 20 languages
  3. What is the purpose of the "stop sequence" parameter in the OCI Generative AI Generation models? It specifies a string that tells the model to stop generating more content. It assigns a penalty to frequently occurring tokens to reduce repetitive text. It controls the randomness of the model's output, affecting its creativity. It determines the maximum number of tokens the model can generate per response.
  1. What does a dedicated RDMA cluster network do during model fine-tuning and inference?
  • It enables the deployment of multiple fine-tuned models within a single cluster. It increases GPU memory requirements for model deployment. It limits the number of fine-tuned models deployable on the same GPU cluster. It leads to higher latency in model inference.
  1. Which role does a "model endpoint" serve in the inference workflow of the OCI Generative AI service? Mark for Re Evaluates the performance metrics of the custom models Hosts the training data for fine-tuning custom models
  • Updates the weights of the base model during the fine-tuning process Serves as a designated point for user requests and model responses
  1. Which is NOT a typical use case for LangSmith Evaluators? Assessing code readability Detecting bias or toxicity Evaluating factual accuracy of outputs Measuring coherence of generated text
  2. What is the primary purpose of LangSmith Tracing? To monitor the performance of language models To analyze the reasoning process of language models
  • To debug issues in language model outputs To generate test cases for language models
  1. Why is normalization of vectors important before indexing in a hybrid search system? It ensures that all vectors represent keywords only. It significantly reduces the size of the database.

It converts all sparse vectors to dense vectors. It standardizes vector lengths for meaningful comparison using metrics such as Cosine Similarity.

  1. How do Dot Product and Cosine Distance differ in their application to comparing text embeddings in natural language processing? Mark for Re Dot Product calculates the literal overlap of words, whereas Cosine Distance evaluates the stylistic similarity. Dot Product assesses the overall similarity in content, whereas Cosine Distance measures topical relevance. Dot Product measures the magnitude and direction of vectors, whereas Cosine Distance focuses on the orientation regardless of magnitude. Dot Product is used for semantic analysis, whereas Cosine Distance is used for syntactic comparisons.
  2. Which is a cost-related benefit of using vector databases with Large Language Models (LLMs)?
    • They require frequent manual updates, which increase operational costs.
    • They offer real-time updated knowledge bases and are cheaper than fine-tuned LLMs.
    • They are more expensive but provide higher quality data.
    • They increase the cost due to the need for real-time updates.
