In LangChain, which retriever search type is used to balance between relevancy and diversity? topK mmr similarity_score_threshold similarity. What does a dedicated RDMA cluster network do during model fine-tuning and inference? It leads to higher latency in model inference. It enables the deployment of multiple fine-tuned models within a single cluster. It limits the number of fine-tuned models deployable on the same GPU cluster. It increases GPU memory requirements for model deployment. Which role does a "model endpoint" serve in the inference workflow of the OCI Generative AI service? Hosts the training data for fine-tuning custom models Evaluates the performance metrics of the custom models Serves as a designated point for user requests and model responses Updates the weights of the base model during the fine-tuning process. Which is a distinguishing feature of "Parameter-Efficient Fine-tuning (PEFT)" as opposed to classic "Fine- tuning" in Large language Model training? PEFT involves only a few or new parameters and uses labeled, task-specific data. PEFT modifies all parameters and uses unlabeled, task-agnostic data. 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. How does the Retrieval-Augmented Generation (RAG) Token technique differ from RAG Sequence when generating a model's response? Unlike RAG Sequence, RAG Token generates the entire response at once without considering individual parts. RAG Token does not use document retrieval but generates responses based on pre-existing knowledge only. RAG Token retrieves documents only at the beginning of the response generation and uses those for the entire content. RAG Token retrieves relevant documents for each part of the response and constructs the answer incrementally. Which component of Retrieval-Augmented Generation (RAG) evaluates and prioritizes the information retrieved by the retrieval system? Retriever Encoder-decoder Ranker Generator. Which statement describes the difference between "Top k" and "Top p" in selecting the next token in the OCI Generative AI Generation models? 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 considers the sum of probabilities of the top tokens, whereas "Top p" select from the "Top k" tokens sorted by probability. Top k and "Top p" both select from the same set of the tokens but use different methods to prioritize them based on frequency. Top k and "Top p" are identical in their approach to token selection but differ in their application of penalties to tokens. Which statement is true about the "Top p" parameter of the OCI Generative AI Generation models? Top p assigns penalties to frequently occurring tokens. Top p determines the maximum number of tokens per response. Top p limits token selection based on the sum of the their probabilities. Top p selects tokens from the "Top k" tokens sorted by probability. What is the primary function of the "temperature" parameter in the OCI Generative AI Generation models? Determines the maximum number of tokens the model can generate per response Specifies a string that tells the model to stop generating more content Assigns a penalty to tokens that have already appeared in the preceding text Controls the randomness of the output, affecting its creativity. What distinguishes the Cohere Embed v3 model from its predecessor in the OCI Generative AI service? Improved retrievals for RetrievaI-Augmented Generation (RAG) systems Capacity to translate text in over 20 languages Support for tokenizing longer sentences Emphasis on syntactic clustering of word embeddings. What is the purpose of the "stop sequence" parameter in the OCI Generative AI Generation models? It controls the randomness of the model’s output, affecting its creativity. It specifies a string that tens the model to stop generating more content. It assigns a penalty to frequently occurring tokens to reduce repetitive text. It determines the maximum number of tokens the model can generate per response. What does a higher number assigned to a token signify in the "Show Likelihoods" feature of the language model token generation? The token is less likely to follow the current token. The token is more likely to follow the current token. The token is unrelated to the current token and will not be used The token the considered in the next generation step. Given the following code: Prompt Template (input_variables["human_input", "city"], template-template) Which statement is true about Prompt Template in relation to input_variables?

Why is normalization of vectors important before indexing in a hybrid search system? It converts all sparse vectors to dense vectors. It significantly reduces the size of the database. It standardizes vector lengths for meaningful comparison using metrics such as Cosine Similarity. It ensures that all vectors represent keywords only. How does the architecture of dedicated AI clusters contribute to minimizing GPU memory overhead for T- Few fine-tuned model inference? By sharing base model weights across multiple fine-tuned models on the same group of GPUs By optimizing GPU memory utilization for each model’s unique parameters. By allocating separate GPUS for each model instance By loading the entire model into GPU memory for efficient processing. You create a fine-tuning dedicated AI cluster to customize a foundational model with your custom training data.
