NVIDIA Exam NCA-AIIO Topic 2 Question 2 Discussion

Actual exam question for NVIDIA's NCA-AIIO exam

Question #: 2
Topic #: 2

You are working with a large healthcare dataset containing millions of patient records. Your goal is to identify patterns and extract actionable insights that could improve patient outcomes. The dataset is highly dimensional, with numerous variables, and requires significant processing power to analyze effectively. Which two techniques are most suitable for extracting meaningful insights from this large, complex dataset? (Select two)

ASMOTE (Synthetic Minority Over-sampling Technique)

BData Augmentation

CBatch Normalization

DK-means Clustering

EDimensionality Reduction (e.g., PCA)

Show Suggested Answer

Suggested Answer: D, E

A large, high-dimensional healthcare dataset requires techniques to uncover patterns and reduce complexity. K-means Clustering (Option D) groups similar patient records (e.g., by symptoms or outcomes), identifying actionable patterns using NVIDIA RAPIDS cuML for GPU acceleration. Dimensionality Reduction (Option E), like PCA, reduces variables to key components, simplifying analysis while preserving insights, also accelerated by RAPIDS on NVIDIA GPUs (e.g., DGX systems).

SMOTE (Option A) addresses class imbalance, not general pattern extraction. Data Augmentation (Option B) enhances training data, not insight extraction. Batch Normalization (Option C) is a training technique, not an analysis tool. NVIDIA's data science tools prioritize clustering and dimensionality reduction for such tasks.

D and E for sure! The key is to find the right balance between complexity and simplicity. K-means and PCA will help us see the big picture without getting bogged down in the details. Although, I do wonder if the patient records contain any hidden superhero powers...

D and E are definitely the way to go. We need to focus on the big picture to extract meaningful insights.

Hmm, I'm not sure about SMOTE and data augmentation. Aren't those more for image processing? I think D and E are the clear winners here. Gotta keep it simple when you're dealing with a massive healthcare dataset.

SMOTE and Data Augmentation might not be the best fit for this type of data. Keeping it simple is definitely the way to go.

I agree, D and E are the best options. With millions of patient records, we need to find ways to simplify the data without losing the valuable insights. K-means and PCA are tried and true methods for this kind of task.

D and E seem like the way to go. K-means clustering can help identify patterns, and dimensionality reduction will make the data more manageable to analyze. The dataset is huge, so we need techniques that can handle the complexity.
