What are the essential skills to become a data scientist?
A data scientist must hold the right skillset in mathematics, coding, and research abilities. They should be curious and continuous learners. After gaining enough knowledge, skills, and experience, one can also aim to become an entrepreneur. Some of the essential skills are:
· Probability & Statistics
Probability & Statistics is required to generate high-quality models. Statistics involves analyzing the dataset to understand the unique mathematical characteristics. Machine Learning begins as statistics and then advances further. The various probability distributions, population, CLT, sample, kurtosis, and skewness are helpful for easily integrating practices such as Bayesian statistics to direct the probability of events depending on the past data and the possibility of recurrence.
· Multivariable Calculus & Linear Algebra
Understanding linear algebra algorithm theory and algorithm functions is essential. An individual should possess knowledge of topics like gradient descent, Lagrange, convex optimization, partial differential equations, quadratic programming, and summations. With this knowledge, one can perform data processing, manipulation, and transformation.
· Data extraction, analysis and visualization
Data Analysis is an ongoing process in data science. Here, the transforming and scrubbing of data into a visual form happens. It is performed in Excel, SQL, and Pandas in Python. Having compelling data visualization is the perfect process to deliver the best results that come from a machine learning algorithm. Always look for the latest data visualization techniques using Python libraries and R packages to get effective results.
· ML algorithms and modeling
Machine learning takes help from advanced algorithms and modeling techniques to receive and analyze input data and predict output values. The gathered data are given to these algorithms to build models, learn and optimize their operations to improve performance, evaluate and use third-party models, and perform cross-validation.
· Programming skills
One of the best skills is a sound knowledge of various programming languages such as C/C++, SQL, Python, Perl, and Java will be a great advantage. Python is the most chosen programming language. Programming language knowledge helps to organize unstructured data sets, transforming them into generating accurate outcomes with high speed and big data processing.
What are the top companies that hire Data Scientists?
In today’s data-driven world, several organizations across various industries are racing to harness the power of data science for better insights and innovation. Among the vanguards of this movement are many tech titans, consistently looking for top-tier talent to fuel their data-driven initiatives. These organizations have established themselves as pioneers in the tech industry and rely on data science for different factors in their operations. A few top companies are:
- Amazon
