Python codes Study guides, Class notes & Summaries

The file contains cheatsheet materials for two M.Sc. DSS core courses, Data Mining for Business & Gov. (880022-M-6) and Machine Learning (880083-M-6). Both cheatsheets have been tested on multiple mock exams as well as used successfully in the actual exams. Includes python codes for Machine Learning. Some information overlaps due to it being covered in both courses.

The summary contains an overview of the material you need to know for the DSA exam. It contains the points you need to know about the theory, plus Python codes.

program The instructions that control computer hardware and make it work. machine language a set of primitive instructions built into every computer. The instructions are in the form of binary code, so you have to enter binary codes for various instructions. Instruction List (IL) The alphabet of a machine language. A complete set of known commands. Different types of computers may vary depending on the size of their _____s, and the instructions could be completely different in different mod...

Learn Models using ML Pipeline in Spark. 2.2.1.2 Specify parameters The next step is setting up parameters for ML algorithms, LogisticRegression. We give 10 for maxIter (Max Iteration) and 0.01 for regParam (Regularization parameter) For detail, see reference [7] After running the above codes in Spark shell, you will see a bunch of parameters you specified, e.g. maxIter and regParam, and can specify or change, aggregationDepth and etc. 2.2.1.3 Learn model Now it’s time to learn mode wi...

Python makes the distinction between integers and floating variables. - Yes When declaring variables in Python, a data type must be specified. - No When setting a boolean variable, the value must start with a capital letter. - Yes A developer wants to make sure a serial number cannot be used in a calculation and that a dollar amount entered as a whole number can have decimals. Then, a message should be displayed to tell a customer the serial number and price for the products. Using the dr...

This contains relevant lines of codes and commands as well as examples for the material of Introduction to Python. This summary does not include theoretical or conceptual parts. This document might be especially useful because it is an allowed exam material, i.e. one can use it during the exam and quickly (control + f) look up relevant commands
