Data Mining using R help:
What R technique would you use to reduce the number of points to make a scatter plot of dataset that has 200,000 points but would still guarantee all the points chosen from the dataset were random selections?
Homework Answers
Try the code "sample"
This will help you to draw smaller sample from the original dataset and you may carryout suitable procedure to infer something about the dataset. (Whatever you want to do)
"sample" will draw a random sample from the dataset
Eg. s = sampl(1:200000, size = n)
If you want to then may add replace = TRUE to do draw with replacement
Then do this data[s,]
This will give what you require
Then draw a scatterplot

Classification in Python: Classification In this assignment, you will practice using the kNN (k-Nearest Neighbors) algorithm to solve a classification problem. The kNN is a simple and robust classifier, which is used in different applications. The goal is to train kNN algorithm to distinguish the species from one another.

Can you please help me with creating this Java Code using the following pseudocode? Make Change Calculator (100 points + 5 ex.cr.) 2019 In this program (closely related to the change calculator done as the prior assignment) you will make “change for a dollar” using the most efficient set of coins possible. In Part A you will give the fewest quarters, dimes, nickels, and pennies possible (i.e., without regard to any ‘limits’ on coin counts), but in Part B you...

K-means clustering K-means clustering is a very well-known method of clustering unlabeled data. The simplicity of the process made it popular to data analysts. The task is to form clusters of similar data objects (points, properties etc.). When the dataset given is unlabeled, we try to make some conclusion about the data by forming clusters. Now, the number of clusters can be pre-determined and number of points can have any range. The main idea behind the process is finding nearest...
