NEW QUESTION 12
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 diffusion model that specializes in producing complex outputs.

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 Retrieval Augmented Generation (RAG) model that uses text as input and output

NEW QUESTION 13
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.

It limits the number of fine-tuned model deployable on the same GPU cluster.

It increases G PU memory requirements for model deployment.

NEW QUESTION 14
What does “Loss” measure in the evaluation of OCI Generative AI fine-tuned models?
The difference between the accuracy of the model at the beginning of training and the accuracy of the deployed model

The difference between the accuracy of the model at the beginning of training and the accuracy of the deployed model

The percentage of incorrect predictions made by the model compared with the total number of predictions in the evaluation

The improvement in accuracy achieved by the model during training on the user-uploaded data set

The level of incorrectness in the models predictions, with lower values indicating better performance

In the evaluation of OCI Generative AI fine-tuned models, “Loss” measures the level of incorrectness in the model’s predictions. It quantifies how far the model’s predictions are from the actual values. Lower loss values indicate better performance, as they reflect a smaller discrepancy between the predicted and true values. The goal during training is to minimize the loss, thereby improving the model’s accuracy and reliability.

NEW QUESTION 15
Which is a key characteristic of the annotation process used in T-Few fine-tuning?

T-Few fine-tuning uses annotated data to adjust a fraction of model weights.

T-Few fine-tuning requires manual annotation of input-output pain.

T- Few fine-tuning involves updating the weights of all layers in the model.

T-Few fine-tuning relies on unsupervised learning techniques for annotation.

NEW QUESTION 16
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 will be the only one considered in the next generation step.

NEW QUESTION 17
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 their probabilities.

Top p selects tokens from the “Top k’ tokens sorted by probability.

NEW QUESTION 18
What is the purpose of the “stop sequence” parameter in the OCI Generative AI Generation models?

It com rob the randomness of the model* output, affecting its creativity.

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 determines the maximum number of tokens the model can generate per response.

NEW QUESTION 19
Which technique involves prompting the Large Language Model (LLM) to emit intermediate reasoning steps as part of its response?

Step-Bock Prompting

Chain-of-Through

Least to most Prompting

In context Learning

Chain-of-Thought prompting involves prompting the Large Language Model (LLM) to emit intermediate reasoning steps as part of its response. This technique helps the model articulate its thought process and reasoning, leading to more transparent and understandable outputs. By breaking down the problem into smaller, logical steps, the model can provide more accurate and detailed responses.

NEW QUESTION 20
What distinguishes the Cohere Embed v3 model from its predecessor in the OCI Generative AI service?

Improved retrievals for Retrieval Augmented Generation (RAG) systems

Capacity to translate text in over u languages

Support for tokenizing longer sentences

Emphasis on syntactic clustering of word embedding’s

NEW QUESTION 21
What does “Loss” measure in the evaluation of OCI Generative AI fine-tuned models?
The difference between the accuracy of the model at the beginning of training and the accuracy of the deployed model

The difference between the accuracy of the model at the beginning of training and the accuracy of the deployed model

The percentage of incorrect predictions made by the model compared with the total number of predictions in the evaluation

The improvement in accuracy achieved by the model during training on the user-uploaded data set

The level of incorrectness in the models predictions, with lower values indicating better performance

NEW QUESTION 24
Which is a key advantage of usingT-Few over Vanilla fine-tuning in the OCI Generative AI service?

Reduced model complexity

Enhanced generalization to unseen data

Increased model interpretability

Foster training time and lower cost

NEW QUESTION 25
You create a fine-tuning dedicated AI cluster to customize a foundational model with your custom training dat a. How many unit hours arc required for fine-tuning if the cluster is active for 10 hours?

10 unit hours

30 unit hours

15 unit hours

40 unit hours

When you create a fine-tuning dedicated AI cluster and it is active for 10 hours, the number of unit hours required for fine-tuning is equal to the duration for which the cluster is active. Therefore, if the cluster is active for 10 hours, it requires 10 unit hours. This calculation assumes that the unit hour measurement directly corresponds to the active time of the cluster.

NEW QUESTION 26
In LangChain, which retriever search type is used to balance between relevancy and diversity?

top k

mmr

similarity_score_threshold

similarity

In LangChain, the “mmr” (Maximal Marginal Relevance) search type is used to balance between relevancy and diversity when retrieving documents. This technique aims to select documents that are not only relevant to the query but also diverse from each other. This helps in avoiding redundancy and ensures that the retrieved set of documents covers a broader aspect of the topic.
Maximal Marginal Relevance (MMR) works by iteratively selecting documents that have high relevance to the query but low similarity to the documents already selected. This ensures that each new document adds new information and perspectives, rather than repeating what is already included.
