1.2. K-Nearest Neighbors (KNN): It is a supervised machine learning algorithm used for classification tasks. It’s a simple and intuitive algorithm that operates based on the principle of similarity between data points. In KNN, the idea is that similar data points tend to have similar labels...
For presenting an algorithm, I recommend using a final model to make predictions, and plot the results anew. Thb DL May 10, 2019 at 12:06 am # Ok, I worked on this today. I fixed this problem. Just in case someone alse has a similar problem. The fact was that when I re...

In recent years, the author has seen many AI-related issues in CTF competitions at home and abroad. Some require players to implement an AI by themselves to automate certain operations; some provide a target AI model that requires players to crack. This article mainly talks about the latter-i...
Ideas to Improve Algorithm Performance This list of ideas is not complete but it is a great start. My goal is to give you lots ideas of things to try, hopefully, one or two ideas that you have not thought of. You often only need one good idea to get a lift. ...
Finally, it looks like the IBk (KNN) may have the lowest error. Let’s investigate further. 12. Click the “Select” button for the “Test base” and choose the lazy.IBk algorithm as the new test base. 13. Click the “Perform test” button to rerun the analysis. 1 2 3 4 5 6 ...
Machine learning engineers choose their particular machine learning algorithm based on the kind of data available and the problem they’re trying to solve. As machines analyze more and more data, they become “smarter” and can adapt to new tasks and challenges. This imitates the way humans lear...
This is an introductory article to K-Means clustering algorithm where we’ve covered what it is, how it works, and how to choose K. In the next article, we’ll walk through the process on how to solve a real world clustering problems using Python’s scikit-learn library. ...
Now, we are not trying to solve all possible problems, but the new hotness in algorithm land may not be the best choice on your specific dataset. My advice is to collect evidence. Entertain the idea that there are other good algorithms and given them a fair shot on your problem. ...
The LogisticRegression algorithm has two recent changes to the default argument values that result in FutureWarning messages. The first has to do with the solver for finding coefficients and the second has to do with how the model should be used to make multi-class classifications. Let’s look...
