One of the most known algorithms used by spell checkers and auto-complete fields is perhaps the Levenshtein algorithm, which basically minimizes the Levenshtein distance between the target word and the user input; or, in other words, the minimum number of missing characters and additions needed to transform a string into...

The purpose of this document is to present the linear classification algorithm SVM. The development of this concept has been based on previous ideas that have supported the development of SVM as an algorithm with good generalization capacity, based on an optimization criterion that minimizes complexity; with which we have...

(GitHub Repo: https://github.com/alulema/SudokuSolverNet) I was revisiting a couple of basic AI concepts: Depth First Search and Constraint Propagation, and I found a very good explanation by Professor Peter Norvig (Solving Every Sudoku Puzzle), I just want to add a couple of simple explanations for a better understanding of the concepts. Constraint...

TensorFlow has several high-level libraries allowing us to reduce time modeling all with core code. TF Estimator makes it simple to create and train models for training, evaluating, predicting and exporting. TF Estimator provides 4 main functions on any kind of estimator: estimator.fit() estimator.evaluate() estimator.predict() estimator.export() All predefined estimators are...

In my two previous posts, we saw how we can perform Linear Regression using TensorFlow, but I’ve used Linear Least Squares Regression and Cholesky Decomposition, both them use matrices to resolve regression, and TensorFlow isn’t a requisite for this, but you can use more general packages like NumPy. One of...
