Supervised Learning correct answers Uses a precise rule to predict outcome Ex: Regression Random Forrest (Predict stock returns) Unsupervised Learning correct answers Uncovers relationships/commonalties/patterns between variables without a model/structure (What stocks are similar to each other) Deep Learning correct answers Mimicking how the brain works, uses multi-layered neural network (Detect investor sentiment using social media) Ex; time series (nerual nets) Fin-tech: correc...

IoT (internet of things) - The multiple networks of devices or tech platforms ("things") that communicate with each other via wireless protocols and without direct human interaction (ex: smart home devices like programmable thermostats) neural networks - AI algorithms that recognize underlying relationships in a set of data through a process that mimics the way the human brain operations (biological neural networks) disruptive technologies - Technologies that create market shocks and cata...

MATH 425 exam 2 all answers correct Unsupervised learning methods are needed when... data only contains features and no label What are some of the possible goals within unsupervised learning framework? One possible goal within the unsupervised learning framework is to discover interesting things about the data that you are working with. This includes questions such as "Are there any subgroups among the observations or variables that we can discover?", and "Do you notice any hi...

In this file, I have summarized all the lectures of Intelligent Systems. I have added lecture notes and summarized important parts of the book. To make the summary more readable (were necessary), I have added illustrations from the slides. Good luck with the exam!

big data - Answer-Sets of data that are too large to be gathered and analyzed by traditional methods. law of large numbers - Answer-A mathematical principle stating that as the number of similar but independent exposure units increases, the relative accuracy of predictions about future outcomes (losses) also increases. data mining - Answer-The analysis of large amounts of data to find new relationships and patterns that will assist in developing business solutions. text mining - Answer-Obt...
