In this post, we introduce the concept of regularization in machine learning. We start with developing a basic understanding of regularization. Next, we look at specific techniques such as parameter norm penalties, including L1 regularization and L2 regularization, followed by a discussion of other approaches to regularization. What is Regularization? In machine learning, regularization

In this post, we introduce the hypothesis space and discuss how machine learning models function as hypotheses. Furthermore, we discuss the challenges encountered when choosing an appropriate machine learning hypothesis and building a model, such as overfitting, underfitting, and the bias-variance tradeoff. The hypothesis space in machine learning is a set of all possible

In machine learning, we distinguish between several types and subtypes of learning and several learning techniques. Broadly speaking, machine learning comprises supervised learning, unsupervised learning, and reinforcement learning. Problems that do not fall neatly into one of these categories can often be classified as semi-supervised learning, self-supervised learning, or multi-instance learning. In supervised learning,

In this post, we will discuss hashing in Java and introduce a few data structures such as hashtables and hashmaps that rely on hashing. What is Hashing? Hashing is a technique that allows a program to store and subsequently find an object in a large collection of items without going through every item. A

In this post, we introduce the priority queue in Java and explain the underlying concept of a heap. What is a Priority Queue in Java? In a priority queue, items are ordered alphabetically in ascending order, numerically in ascending order, or according to a user-defined attribute based on a custom comparator. In a priority

In this post we learn how to implement a queue in Java using the linked list and priority queue data structures provided by Java. What is a Queue in Java? A queue is a data structure in Java and many other programming languages. Elements are added according to the FIFO (first-in, first-out) principle. An

In this post we look at the stack in Java, a data structure that operates on the LIFO principle. We discuss (clicking the link will take you to the section): What is a Stack How to implement a Stack using collections and deque How to implement a Java stack from scratch What is a

Java is one of the most widely used programming languages in the world today. It powers applications ranging from enterprise software systems to Android apps. Learning it can open the door to plenty of well-paid job opportunities. People who have mastered the art of developing software in Java are hot commodities in the job

In. this post we introduce and define the array data structure in java, how to use it and what common operations can be performed using arrays. What is an Array in Java? An array is a fixed-length Java container object that contains other objects of the same type. An array’s length and the type

In this post, we define the t-test in statistics, explain what different t-tests exist, and demonstrate by example how we can use them to find the differences between means in various scenarios. What is a T-Test? The t-test tests the significance of the difference of measured means. Differences can be measured within the same
