ML is actually a lot many things. The field is quite vast and is expanding rapidly.
Machine Learning is the subfield of Computer Science that gives computers the ability to learn without being explicitly programmed. (Arthur Samuel,1959) […]
Data Science Blog Listing
A multidisciplinary fuse of data inference, algorithm development, and technology to solve analytically complex problems is known as Data science.
Data science is eventually about using this data in creative ways to generate business value.
Data Science is divided into two sub plots.
1. Discovery of data insight which helps quantitative data analysis to help steer strategic business decisions
2. Development of Data product, consists of algorithm solutions in production, opening at scale. For example, recommendation engines. […]
My previous blog, I presented syntactical differences and similar functions between R & Python. Now, I want to take it to next level and write some machine learning algorithms using both R and Python. Here, one may use direct functions from the packages available. However, here I am presenting the way to write your own functions for algorithms. In this series, I am starting with Gradient descent algorithm. I briefly explain, what is gradient descent. After that, I apply gradient descent algorithm for a linear regression to identify parameters. For illustration, I simulate data for simple linear regression. […]
We are going to compare Functions exist in both R and Python for same operations. And for this we took the Titanic dataset which contains the Passenger details.
Importing a CSV
Reading Data in both the languages is similar, but the only difference is for python we have to import pandas library for reading the Data. Once the importing is done we can look into the data by applying the below functions. […]
What skills are required to be a Data Scientist?
Is strong mathematics background required to pursue a career as a data scientist?
We at Rang Technologies see a lot of questions like this. It’s hard when you’re trying to break into the field to know exactly how much math & stats you need. […]
Forecasting is a common technique used in several companies to make predictions for the future. There are multiple methods of forecasting such as time series forecasting, multivariate forecasting, etc. In each of these methods there are techniques such as Moving Average (MA), ARIMA, ARMA, ARCH, GARCH, etc. […]
It’s been a month and what a month it has been! The new year is here already! One wonders where all the time has gone! I hope you also wonder on how far you have come in the process of learning and equipping yourself towards a successful career and life and take pride in it! This ‘present’ day’s effort will grant you the ‘gift’ of future! […]
