You are building a multimodal generative A1 application that uses CLIP to align text and image embeddings. You observe that the generated images lack detail and fidelity to the text prompt. Which of the following strategies would be MOST effective in improving image quality, and how could prompt engineering and Triton Inference Server play a role?
A. Refining the text prompts to be more descriptive and specific, incorporating stylistic details and relevant keywords. Triton can optimize the prompt embedding process.
B. All of the above
C. Using a larger batch size during CLIP training and increasing the learning rate. Triton is not directly involved in model training.
D. Training a separate image super-resolution model to enhance the generated images after they are produced by the CLIP-guided generator. Triton can manage the concurrent execution of the generator and super-resolution models.
E. Increasing the CLIP model's text encoder's hidden layer size and using more aggressive data augmentation during CLIP training. Triton can be used to serve the augmented CLIP model at scale.

質問 5:
A multimodal dataset consists of video footage of human actions and corresponding wearable sensor data (accelerometer, gyroscope). The goal is to predict the type of action being performed. However, the sensor data is noisy and often misaligned with the video frames. Consider the following code snippet designed to synchronize and clean the sensor data:
What is the primary purpose of the 'resample' function in this code, and what potential issues might arise from using a simple aggregation method during resampling?
A. The 'resample' function filters the sensor data and .mean() only returns the most relevant sensor data
B. The 'resample' function increases the sensor data frequency. Using .mean()' is only useful if there is no noise in the sensor data
C. The 'resample' function aligns the sensor data to the video frame rate. Using is appropriate as it averages out the noise in the sensor data.
D. The 'resample' function decreases the video framerate to the rate of the sensor. Using .mean()' is only useful if there is no noise in the sensor data
E. The 'resample' function aligns the sensor data to the video frame rate. Using '.mean()' might smooth out important peaks and valleys in the sensor data, potentially losing crucial information.
正解:E
