C++ hasn’t yet caught up with implementing 2D arrays like other languages yet. So there is no inbuilt 2D array in C++.But lose no hope, with some template programming to the rescue we can create our own multidimensional data structure. Read more…
Below is an implementation of thread-safe queue using synchronization primitives.
A C++ string class can be implemented in more than one way. I used char*(or rather T*) as a base for implementation. The reason for templatization was to mimic the way standard library does things. It supports all the construction, Read more…
There are 2 ways in C++ to get the size of an array. The first is using run-time computation with sizeof, but there is a better compile-time way to compute the size. The way to do it as follows: Note: Read more…
Topological Sort is used to find a linear ordering of elements that have dependencies on each other. For example, if event ‘B’ is dependent on event ‘A’, ‘A’ comes before ‘B’ in topological ordering. Lets say we are asked to find Read more…
To measure how well our models are performing we may need to define some metrics. One of the metrics which is quite straight forward is accuracy. Accuracy is defined as the number of correctly classified points divided by the total Read more…
Median Absolute deviation is one of the other techniques specifically used for analyzing the performance of regression models. Computing MAD of errors For a univariate data set X1, X2, …, Xn, the MAD is defined as the median of the Read more…
Writing clean code is more of an art rather than a science. So What really makes code cleaner?. In this series called Clean Code Concepts, we investigate some of the ways to write code in a clean way. There are several Read more…
R-squared is a statistical measure of how close the data are to the fitted regression line. It is also known as the coefficient of determination, or the coefficient of multiple determination for multiple regression. This metric is specifically designed for Read more…
We can plot error distributions like probability density functionand cumulative density function and make important deductionsbased on it. We can use plot Probability Density functions(PDF) and Cumulative density function (CDF) by using the error function as a random variable Using Read more…
