Interview Questions
What is the Azure Machine Learning designer?
Azure Machine Learning designer is a visual interface that allows you to build, test, and deploy predictive analytics solutions without writing code.
What are the two main elements that are dragged and connected to create experiments in the Azure Machine Learning designer?
The two main elements are Datasets and Modules.
What is a dataset in the context of the Azure Machine Learning designer?
A dataset in Azure Machine Learning designer refers to the data that is used to train, test, and deploy machine learning models. Datasets can come from various sources, like Azure Storage or local files.
What is a module in the context of the Azure Machine Learning designer?
A module in Azure Machine Learning designer refers to a prebuilt set of algorithms and functions to perform tasks such as data transformation, model training, scoring, and evaluation.
How is a predictive experiment different from a training experiment in the Azure Machine Learning designer?
A training experiment involves preparing data, training a model, and testing the model. However, a predictive experiment uses the trained model to make predictions off of new input data.
Can we use Python or R in the Azure Machine Learning designer?
Yes, Azure Machine Learning designer supports the use of Python and R scripts within the framework of an experiment by using the respective Python or R Language Modules.
How can you convert a training experiment to a predictive experiment in Azure Machine Learning designer?
To convert a training experiment to a predictive experiment, you can save your trained model and then create a new predictive experiment. Within this new predictive experiment, you replace the training and model evaluation modules with a web service input and output.
What is the purpose of the “Score Model” module in the Azure Machine Learning designer?
The “Score Model” module is used to generate predictions by applying the trained machine learning model to new data.
What is a web service in the context of Azure Machine Learning Designer?
A web service in Azure Machine Learning is a way to expose your model over the internet, enabling other users or systems to use your model to perform predictions.
What’s the purpose of the “Train Model” module in Azure Machine Learning designer?
The “Train Model” module is used to create a machine learning model using a specific algorithm and a training dataset. It requires the untrained model as well as a dataset to perform the training process.
What is an evaluation result in Azure Machine Learning Designer?
An evaluation result refers to the output of the Evaluating model module, which provides key metrics that help to assess the performance of a trained model against a test dataset.
What is the purpose of the “Split Data” module in the Azure Machine Learning designer?
The “Split Data” module is used to separate your data into two partitions. This is typically used to create a training dataset and a test dataset for model training and test purposes respectively.
How can the ‘Parameter Sweep’ module be used in the Azure Machine Learning designer?
The ‘Parameter Sweep’ module can be used to automatically try multiple combinations of parameters for a machine learning algorithm to find the combination that produces the best model.
How does the Azure Machine Learning designer allow for reproducibility and sharing of experiments?
Experiments in Azure Machine Learning designer are saved in the cloud, therefore they can be shared through a simple link or cloned for replication.
What are the two types of web services available in Azure Machine Learning that can be used to publish experiments?
The two types of services are: a request/response service (also known as Real-time Inferencing) and a batch execution service (also known as Pipeline Endpoint).
