Your team is building a convolutional neural network (CNN)-based architecture from scratch. The preliminary experiments running on your on-premises CPU-only infrastructure were encouraging, but have slow convergence. You have been asked to speed up model training to reduce time-to-market. You want to experiment with virtual machines (VMs) on Google Cloud to leverage more powerful hardware. Your code does not include any manual device placement and has not been wrapped in Estimator model-level abstraction. Which environment should you train your model on?
A. AVM on Compute Engine and 1 TPU with all dependencies installed manually.
B. AVM on Compute Engine and 8 GPUs with all dependencies installed manually.
C. A Deep Learning VM with an n1-standard-2 machine and 1 GPU with all libraries pre-installed.
D. A Deep Learning VM with more powerful CPU e2-highcpu-16 machines with all libraries pre-installed.
You need to quickly build and train a model to predict the sentiment of customer reviews with custom categories without writing code. You do not have enough data to train a model from scratch. The resulting model should have high predictive performance. Which service should you use?
A. AutoML Natural Language
B. Cloud Natural Language API
C. AI Hub pre-made Jupyter Notebooks
D. AI Platform Training built-in algorithms
You need to train a natural language model to perform text classification on product descriptions that contain millions of examples and 100,000 unique words. You want to preprocess the words individually so that they can be fed into a recurrent neural network. What should you do?
A. Create a hot-encoding of words, and feed the encodings into your model.
B. Identify word embeddings from a pre-trained model, and use the embeddings in your model.
C. Sort the words by frequency of occurrence, and use the frequencies as the encodings in your model.
D. Assign a numerical value to each word from 1 to 100,000 and feed the values as inputs in your model.
You are an ML engineer in the contact center of a large enterprise. You need to build a sentiment analysis tool that predicts customer sentiment from recorded phone conversations. You need to identify the best approach to building a model while ensuring that the gender, age, and cultural differences of the customers who called the contact center do not impact any stage of the model development pipeline and results. What should you do?
A. Convert the speech to text and extract sentiments based on the sentences.
B. Convert the speech to text and build a model based on the words.
C. Extract sentiment directly from the voice recordings.
D. Convert the speech to text and extract sentiment using syntactical analysis.
You are an ML engineer at a mobile gaming company. A data scientist on your team recently trained a TensorFlow model, and you are responsible for deploying this model into a mobile application. You discover that the inference latency of the current model doesn't meet production requirements. You need to reduce the inference time by 50%, and you are willing to accept a small decrease in model accuracy in order to reach the latency requirement. Without training a new model, which model optimization technique for reducing latency should you try first?
A. Weight pruning
B. Dynamic range quantization
C. Model distillation
D. Dimensionality reduction
