Data Optimization Techniques for Data Scientist
This article is about the importance of optimization techniques for a data scientist. Data science is a field that covers everything related to data analysis, data cleansing, and data preparation.
Are you looking for optimization techniques for data scientist? If yes then this article is for you. As a data scientist, we spent a lot of our time in making better decisions. We are always looking to fabricate the predictive models to provide enhanced insights. Here in this article, you will not get the information about making better predictions, but instead how to make the best decision. Here you’ll get to know about some of the unique methods of optimizing your python code.
Data optimization techniques Purpose
Data science and AI-based streamlining have likewise to a great extent been utilized to take care of issues identified with logical programming. Composing advanced Python code is extremely, significant as a data scientist. Writing a messy or wasteful scratch pad will cost you time and your venture a great deal of money.
As experienced information researchers and experts know, this is inadmissible when we’re working with a customer. Different models are accounted for by the writing on the task in knowledge discovery, distributed/parallel systems, high-performance computing, data analysis, large-scale data mining, text analysis, optimization for manufacturing, distributed/parallel search, scheduling, and finance and civil engineering, among others.
In this sense, this region gives a wide arrangement of exploration lines and applications that must be explored. By using code optimization methods we can reduce the number of operations to carry out any task while producing the right results.
Optimization methods in data science: Convergent Parallel Algorithms
When managing big data issues it is essential to structure strategies (structured and unstructured) ready to decay the first issue into smaller and more controllable pieces. While dealing with larger datasets there are some issues that might occur i.e. the training of Support Vector Machines might get difficult to manage, time management, and memory management issues.
To conquer these drawbacks a lot of parallel algorithms (optimization algorithms) have been introduced and successfully implemented by most of the data scientists. The convergent parallel algorithms lead to an answer by simultaneously dealing with various pieces that are dispersed among accessible specialists so that abusing the computational intensity of multi-center processors and accordingly proficiently tackling the issue.
Similarly, the gradient-type methods can also be easily parallelized but sometimes it suffers from practical drawbacks. To deal with optimization problem, a convergent decomposition framework for the parallel optimization of (possibly non-convex) big data problems were projected. The framework is very supple and includes both fully sequential and fully parallel schemes. The framework also helps in dealing with different big data problem included logistic regression, support vector machines training, and LASSO.
Optimization methods in data science: Limited Memory Bundle Algorithm
Most of the big data problems entail non-smooth functions of hundreds and thousands of variables with different constraints. This will sometimes bring a lot of issues. Non-smooth optimization is usually based on convex examination and most solution methods rely robustly on the convexity of the setback. Different efficient adaptive limited memory bundle methods are developed for providing outsized, possible non-convex, and inequality constrained optimization.
Methods to Optimize your Python Code
Being a data scientist, there are some methods by using to which you can optimize your python code for your project. Optimizing your python code will not only save your time but it also helps in saving a lot of computational power. To get the best possible outcome, we must use some optimized techniques to get the results quickly. Some of the best techniques that most of the data scientist used to improve and optimize their Python code are as follows:
1.) Pandas.apply() – A Feature Engineering Gem
Pandas is a profoundly streamlined library however the majority of us do not know how to make use of it. Consider the normal spots in your data science project where you use it.
One of the amazing functionality of this library is “Feature Engineering”. This feature helps in creating new features using existing features. This feature is a standout amongst other additional items to the Pandas library as this capacity assists with isolating information as per the conditions required.
We can then proficiently utilize it for data manipulation tasks.
2.) Pandas.DataFrame.loc – A Brilliant Hack for Data Manipulation in Python
This method is highly preferred for those who deal with data manipulation tasks. While working on some project we are required to update some values of a particular column or row in a dataset based upon some conditions.
This method can help us in performing that operation more effectively. “Pandas.DataFrame.loc” provides the most optimized solution for these kinds of optimization problem.
3.) Multi data processing in Python
It provides an ability to get support from more than one processor at a time. For using this method we smash our progression into multiple tasks and all of them run in parallel. It will help in speeding things up.
4.) Vectorize your Functions in Python
This method can help in getting rid of slow loops. Using a vectorizing method in your python code will speed up your calculation by at least two iterations. The vectorization method not only speeds up your code but also makes it look cleaner.
Data optimization techniques: Conclusion
Handling different types of data and the large amount of data collected is not an easy job to do. Often, newcomers in the field of Data Science (DS) and Machine Learning (ML) are encouraged to become familiar with everything related to linear algebra and statistics. The utility of a solid establishment in these two subjects is important for an effective career in DS/ML. However, optimization is equally important if you are looking for the best possible outcomes.
Neural Networks are also a great optimization algorithms in providing optimized big data in real time.
