Calculus:  Integration, Differentiation, Partial Derivatives, Directional Derivatives, Vector-Values Functions, Gradient, Jacobian, Laplacian, Hessian, Lagrangian Distribution, and more.


For those who want to start a career in data science from the scratch, the knowledge of statistical calculations is a must. It is an essential concept for the production of high-quality models - one should understand the concepts of Measures of Central Tendency, Measures of Dispersion, Statistical Tests, Descriptive Statistics, Standard Deviation, and Samples or Inferential Statistics.

Programming Languages

You must have proficiency in at least one programming language as a data scientist in Nepal. Python is the most common programming language among data scientists in Nepal. Other programming language options to start a career in data science are JavaScript, Java, C/C++, R, SQL, MATLAB, and Scala. Python is preferred mostly because it is an open-source programming language with inbuilt libraries such as Matplotlib, NumPy, Scikit-Learn, Pandas, TensorFlow, PyTorch, Keras, Theano, and more, which are essential to facilitate data science tasks.

Data Analysis

As a data scientist, you must know how to analyze and manipulate data. Once you have your findings on your plate, you should be able to present them to the audience or the responsible person live. You must learn a few data analysis tools to build a career in data science. Knowledge of tools like MS Excel, Tableau, Looker, Google Data Studio, and SQL, is essential for a data scientist.

Machine Learning

Machine learning is a must-have skill to start a career in data science as it is essential to create predictive models, drawing on data to predict trends and patterns. Machine Learning algorithms such as linear and logistic regression, SVM, Naive Bayes, decision trees, and more are used in determining and solving real-life data problems. As a data scientist, you must know how these algorithms work, how to configure hyperparameters, and which machine learning models should be used to solve the problems and reduce the error rate of the models.

Data Visualization

Understanding the basics of data visualization is essential to start with data science. You should not be a good graphic designer but know how to create data reports and present them to the audience. Having a good knowledge of data visualization and reporting tools such as Tableau, QlikView, Microsoft Power BI, MS Excel, Google Charts, Datawrapper, Grafana, Chartist. js, FusionCharts, Infogram, Plotly, Zoho analytics, etc can help you with data visualization.

Take a Data Science Course in Nepal

Even though you have a fine knowledge of data science, never stop learning and upskill yourself. Keep reading academic articles and watching data science videos to improve your technical skills and innovative capacity. It helps you keep a balance in your professional skills. You can even join a data science course in Nepal to stay on top of the latest trends in data science. Data science training in Nepal helps you expand your knowledge and enhance your learning experience base in the domain, ultimately sharpening your existing data science skills. You can enroll in a data science program in Nepal at TechAxis, a leading IT training institute in Nepal.

Build Your Data Science Job Portfolio

Employers often won’t pay attention to you if you have knowledge but have not done the work before. Develop your own projects that involve data science tools which will be helpful for you to showcase yourself as a data scientist to employers. Build at least five projects relevant to the data science job and put them in your data science job portfolio.
