質問 # 11
Which of the following techniques are MOST effective for improving the energy efficiency of a large-scale Generative A1 model during inference, while minimizing performance degradation?
正解：A、C、D
解説：
Model quantization reduces the memory footprint and computational cost by representing weights with fewer bits. Knowledge distillation trains a smaller, faster model to mimic the behavior of a larger model. Pruning removes redundant connections, reducing the number of computations. Gradient accumulation is for training, not inference. Increasing batch size may improve throughput but not necessarily energy efficiency per sample and might even decrease it due to increased memory usage.
質問 # 12
You are developing a text-to-image generation system using a diffusion model. During inference, you notice that the generated images often contain artifacts or inconsistencies. What is the most appropriate strategy to reduce these artifacts and improve the overall image quality?
正解：C
解説：
Increasing the number of diffusion steps allows the model to more accurately refine the image during the reverse diffusion process, leading to fewer artifacts and a smoother, more consistent output. Decreasing the guidance scale might reduce adherence to the text prompt. A simpler text encoder might reduce detail. While training with a larger dataset is always beneficial, it's not a direct solution to existing artifacts during inference. Batch size primarily impacts memory usage and throughput, not individual image quality.
質問 # 13
You are training a multimodal generative A1 model for image captioning. After initial training, you observe that the model excels at describing common objects but struggles with nuanced details and rare objects. Which of the following performance optimization strategies would be MOST effective in addressing this issue?
正解：B
解説：
Implementing a custom loss function is the most effective strategy because it directly addresses the model's weakness by focusing on accurate descriptions of rare objects. Increasing batch size improves training speed but not necessarily accuracy. Early stopping prevents overfitting, but doesn't specifically target the issue of rare object recognition. Reducing the learning rate might help with fine-tuning, but not as effectively as a targeted loss function. Increasing the number of layers may increase complexity but not guarantee better performance on rare objects.
質問 # 14
Which of the following losses are suitable and can be used when training a Variational Autoencoder (VAE)?
正解：B、C、D
解説：
VAEs typically use a combination of reconstruction loss (cross-entropy or MSE, depending on the data type) to ensure the decoder can accurately reconstruct the input, and KL divergence loss to enforce a prior distribution on the latent space. Hinge loss is commonly used in SVMs and contrastive loss is used in siamese networks to learn embeddings. Reconstruction loss based on Cross-entropy is used for descrete value as in binary classification, and MSE is used to capture how different each generated pixel from the corresponding pixel, which encourages the network to create accurate reconstruction.
質問 # 15
You are tasked with developing an image processing model using machine learning. You need to classify thousands of labeled images of cats and dogs. Which algorithm is commonly used for image classification?
正解：C
解説：
CNNs remain the standard architecture for image classification tasks of this kind, for the same structural reasons covered elsewhere in this set: convolutional layers exploit spatial locality and translation invariance in image data, learning hierarchical features - edges and textures in early layers, parts and objects in deeper layers - directly from labeled pixel data, without requiring hand-engineered features. With thousands of labeled cat/dog images, a CNN (trained from scratch or, more efficiently given the modest dataset size, fine- tuned from a pretrained backbone via transfer learning) is the practical, industry-standard choice.
Decision Trees (A) can technically be applied to hand-engineered image features, but they scale poorly to raw high-dimensional pixel input and cannot learn spatial hierarchies the way convolutional architectures do - they're a reasonable choice for structured/tabular data, not raw image classification. K-Means Clustering (B) is unsupervised and would group images by similarity without using the provided labels at all, making it unsuitable for a labeled classification task where you already have ground-truth cat/dog annotations to learn from directly. Linear Regression (D) predicts continuous numeric outputs and is not designed for categorical classification; even logistic regression, its classification-oriented cousin, would struggle on raw pixels without the feature-learning capacity a CNN provides.
This mirrors a nearly identical question earlier in this set (10,000 cats/dogs/birds) - expect the exam to test this CNN-for-images association repeatedly, sometimes with different distractor combinations.
