Implementation KNN- Classifier in Python

As we previously examine the KNN that how it works and how to select the K for better outcomes and no overfitting. In this article, we will be going to code the python version for KNN and we will find the most immeasurable value of K to use for better outcomes.

Find the below code with explanation:

Import the necessary libraries which we will need for the future.

Now load the dataset from the local and find how rows look in it.

To download the dataset please refer to the following link.

Now select all the features and the target_class from the set and divide the set into test and train by 33% and 67%.

Now for a range values of K fit on the training dataset and then test on the test dataset and find the accuracy and then store it into some array.

Now plot the K-values with their corresponding accuracy and see which value is best.

Now we have our model and we can predict any given unknown value with more accuracy because now we know the best value of k.

Thanks for browsing my pattern, and I hope it benefits you in theory and in practice!!!!

Random Forest and how it works

Random Forest Random Forest is a Machine Learning Algorithm based on Decision Trees. Random forest works on the ensemble method which is very common these days. The ensemble method means that to make a decision collectively based on the decision trees. Actually, we make a prediction, not simply based on One Decision Tree, but by an unanimous Prediction, made by ‘ K’ Decision Trees. Why should we use There are four reasons why should we us e the random forest algorithm. The one is that it can be used for both classification and regression businesses. Overfitting is one critical problem that may make the results worse, but for the Random Forest algorithm, if there are enough trees in the forest, the classifier won’t overfit the model. The third reason is the classifier of Random Forest can handle missing values , and the last advantage is that the Random Forest classifier can be modeled for categorical values. How does the Random...

How to be a HERO in Machine Learning/Data Science Competitions

At present to master machine learning models one has to participate in the competition which is appearing in various platforms. So how somebody who is new to ml can become a hero from zero . The guideline is in this article. The idea for this is not too hard. Just patience and some hard work are required. I will take an example of a Competition that is just finished within top 10. So the competition generally gives you the problem in which some of the features are hidden because they want you to explore the data and come up with the feature that explains the target value. By exploring I mean to say the few things: Look at the data. Get the sense of the data. Find the correlation of all features with a target value. Try new features made up of existing features. Exploration needs some cleaning of the data also. Because in general, the host will add the noise into the data so that it becomes a trouble for us to achieve good accuracy. By cleaning I...

DBSCAN Clustering Algorithm-with maths

DBSCAN is a short-form of D ensity- B ased S patial C lustering of A pplications with N oise. It is an unsupervised algorithm that will take the set of points and make them into some sets which have the same properties. It is based on the density-based clustering and it will mark the outliers also which do not lie in any of the cluster or set. There are some terms that we need to know before we proceed further for algorithm: Density Reachability A point “p” is said to be density reachable from a point “q” if point “p” is within ε distance from point “q” and “q” has a sufficient number of points in its neighbors which are within distance ε. Density Connectivity A point “p” and “q” are said to be density connected if there exists a point “r” which has a sufficient number of points in its neighbors and both the points “p” and “q” is within the ε distance. This is a chaining process. So, if “q” is neighbor of “r”, “r” is neighbor of “s”, “s” ...
