- Data Structure

Data structure is a way of data organization, management, and storage format that enables efficient access and modification.

- Data Structure / python

In a singly linked list, we have an ordered list of items as individual Nodes that have pointers to other Nodes.

- Data Structure

A singly linked list, in its simplest form, is a collection of nodes that collectively form a linear sequence. Each node stores a reference to an object that is an element of the sequence, as well as a reference to the next node of the list.

- Algorithm / Data Structure

Big-O notation is a relative representation of the complexity of an algorithm.

- AI / Deep learning

The pioneering CNN models in the ILSVRC through the years and a history of ... thanks for your article, very nice overview of different architectures! ... A Convolutional Neural Network (CNN, or ConvNet) are a special kind of multi-layer ... Here I will talk about CNN architectures of ILSVRC top competitors .

- Data Structure / python

A deque, also known as a double-ended queue, is an ordered collection of items similar to the queue. It has two ends, a front, and rear, and the items remain positioned in the collection.

- Data Structure / python

A queue is an ordered collection of items where the addition of new items happens at one end, called the “rear,” and the removal of existing items occurs at the other end, commonly called the “front.”

- Data Structure / python

A stack is an ordered collection of items where the addition of new items and the removal of existing items always takes place at the same end.

Linear Regression in Machine Learning is one of the most fundamental algorithm. It is the door to the magical world ahead, but before going further with algorithm. Let's have a look at the life cycle of Machine Learning model.
