Why Should You Care About Machine Learning?
When I say machine learning, it reminds me a subject for the B.Tech Mechanical stream. No this is not a session of machine learning or it’s not related to your regular subject knowledge. The topic remains the same but it’s still different. So before we go to the point why should we be bothered about what is machine learning. We should now see what is machine learning actually.What is Machine Learning?Machine learning is a subcategory or to a say, a type of artificial intelligence (AI) which gives computers, a privilege to learn without being explicitly programmed. It mainly focuses on ...

In data communications and networking, orthogonal frequency-division multiplexing (OFDM) is a method of digital data modulation, whereby a single stream of data is divided into several separate sub-streams for transmission via multiple channels.OFDM uses the principle of frequency division multiplexing (FDM), where the available bandwidth is divided into a set of sub-streams having separate frequency bands. OFDM was introduced in 1966 by Chang at Bell Labs and was improved by Weinstein and Ebert in 1971.Working Principle of OFDMOFDM is a specialised FDM having the constraint that the sub-streams in which the main signal is divided, are orthogonal to each other. ...

Asymptotic AnalysisUsing asymptotic analysis, we can get an idea about the performance of the algorithm based on the input size. We should not calculate the exact running time, but we should find the relation between the running time and the input size. We should follow the running time when the size of input is increased.For the space complexity, our goal is to get the relation or function that how much space in the main memory is occupied to complete the algorithm.Asymptotic BehaviorFor a function f(n) the asymptotic behavior is the growth of f(n) as n gets large. Small input values ...
