Machine Learning Machine learning is defined as an automated process that extracts patterns from data. Supervised Machine Learning To build the models used in predictive data analytics applications, we used supervised machine learning. Supervised machine learning techniques automatically learn a model of the relationship between a set of descriptive features and a target feature based on a set of historical examples, or instances. We can use this model to make predictions for new instan...

1. You are developing an application that will only recognize and tag specific business to business product logos in images. You do not have an extensive background working with machine learning models, but need to get your application working. What is the current best method to accomplish this task? correct answers a. Use the AutoML Vision service to train a custom model using the Vision API i. The newly added AutoML services allow you to train custom image (and other models) using the Google...

Explain the difference between descriptive, predictive, and prescriptive modeling - Answer- Descriptive - focuses on what happened in the past and aims to describe the observed trends by identifying relationships between variables. Predictive - What will happen in the future and making accurate predictions. Prescriptive - Combo of optimization and simulation to investigate the impact of prescribed actions in different scenarios. Explain the difference between supervised and unsupervised le...

The biodesign process for developing medical technologies can be summarized in the diagram below by Paul Yock (Biodesign, Cambridge University Press, 2015): Design P At which stage in the process are you too far along to go backwards? a. After inventing a prototype b. Never - you can go backwards at any point and start over c. After interviewing stakeholders to determine the need d. After selecting the final project e. After writing the Need Statement f. After making observations and/o...

AIDA 181 Study Guide 2023 with complete solution big data - sets of data that are to large to be gathered and alayszed by traditional methods 5 Vs of big data - volume variety velocity veracity value volume - far larger (consumes more storage space) than traditional data stores variety - much of the data exists in multiple unstructured (this is defined later) formats velocity - speed at which the data arrives and the rate of evolution veracity - the co...

Amanda is measuring the temperature. She looks at the thermometer and sees that it is somewhere between 65 and 66 degrees Fahrenheit. She is okay with the temperature in between two integers because she knows temperature is not ________ data, but temperature is _________ data.  a) Nominal, Ordinal  b) Nominal, Discrete  c) Continuous, Discrete  d) Discrete, Continuous Feedback: The correct answer is D. Temperature is not a measure that comes in increments (discrete) but is co...

What is ChatGPT? ChatGPT, by OpenAI, is a conversational language model, which means it can answer questions or perform tasks that yield a text-based response. Standard chatbot vs. ChatGPT Standard chatbots are usually designed to return a predetermined response to a limited number of questions. ChatGPT is far more generalizable, as it uses its understanding of language to interpret the question or task and determine the most appropriate response. Generative AI ChatGPT is an ...
