Using pandas, fit a K-nearest neighbors model with a value of `k=3` to this data and predict the outcome on the same data. Then, write a function to calculate accuracy using the actual and predicted labels and use the function, to calculate the accuracy of this K-nearest neighbors model on the data.
Afterward, fit the K-nearest neighbors model again with `n_neighbors=3`, but apply a strategy through which the distance of neighbors will be counted or valued. So, this time use distance for the weights. Calculate the accuracy using the function created above. (use a value of 1.0 for weighted distances). Then, fit another K-nearest neighbors model. This time use uniform weights but set the power parameter for the Minkowski distance metric to be 1 (`p=1`) i.e. Manhattan Distance. Finally fit a K-nearest neighbors model using values of `k` (`n_neighbors`) ranging from 1 to 20. Use uniform weights (the default). The coefficient for the Minkowski distance (`p`) can be set to either 1 or 2--just be consistent. Store the accuracy and the value of `k` used from each of these fits in a list or dictionary. Plot (or view the table of) the `accuracy` vs `k`. What do you notice happens when `k=1`? Why do you think this is?

You found that in-sample R2 over the training sample is 70% and the out-of-sample R2 over the test sample only - 30%. (select all that apply) a) Do you think there is any problem and how would you characterize it? Can adding more regressors (if you have them) help the model? b) Which approaches you may use to solve the problem? c) What would you expect the in-sample R2 to increase or decrease after that? What about the out-of-sample (test) R2?arrow_forwardClassify the 1’s, 2’s, 3’s for the zip code data in R. (a) Use the k-nearest neighbor classification with k = 1, 3, 5, 7, 15. Report both the training and test errors for each choice. (b) Implement the LDA method and report its training and testing errors. Note: Before carrying out the LDA analysis, consider deleting variable 16 first from the data, since it takes constant values and may cause the singularity of the covariance matrix. In general, a constant variable does not have a discriminating power to separate two classes.arrow_forward
- Keep the answer medium in length, not too long and not too short.arrow_forwardWe would like to learn a model to predict whether a monster is scary or not (S). We identify four features for this purpose: Number of eyes (N), Color of eyes (C), Height (H), and Odor (O). We collect data 8 monster as shown below. Rank these four features according to their mutual information with S. Make sure to identify ties.arrow_forwardI am completely lost for this practice for Machine Learning. There was no solution provided for this.Train a decision tree to predict whether a person makes over 50ドルK a year based on the UCI Adult Census Income dataset. This database contains 48842 instances. Each instance is described in terms of 14 attributes. The last column attribute named "income" is the binary outcome to predict (i.e., ≤ 50K or otherwise). Note there are both numeric and discrete attributes.Cannot allowed to use libraries to such as SciKit to help. Code must be in Python. Tasks: The data set can be downloaded from the website https://www.kaggle.com/ uciml/adult-census-income. After downloading the data set, please split it into training set (70%), validation set (10%) and test set (20%). Implement the C4.5 decision tree algorithm. Your implementation should let user determine when to stop the recursive splitting. Run your algorithm on the training set to learn a decision tree using the following cut-off values,...arrow_forward
- You are working on a spam classification system using regularized logistic regression. "Spam" is a positive class (y = 1)and "not spam" is the negative class (y=0). You have trained your classifier and there are m= 1000 examples in the cross-validation set. The chart of predicted class vs. actual class is: Predicted class: 1 Predicted class: 0 Actual class: 1 85 15 For reference: Accuracy = (true positives + true negatives)/(total examples) Precision = (true positives)/(true positives + false positives) Recall = (true positives)/ (true positives + false negatives) F1 score = (2* precision * recall)/(precision + recall) What is the classifier's F1 score (as a value from 0 to 1)?

If we had the density of observation within a cluster smaller than the density around an outlier, explain why we would have such a situation. And provide a solution to this problem.arrow_forward
