6. Keras
Keras is a python API that aims to provide a simple interface for working with neural networks. Popular deep learning libraries like Tensorflow are notorious for not being very user-friendly. Keras sits on top of these frameworks and provides a friendly way to interact with them.
Keras supports convolutional and recurrent networks, sponsors multi-backends, and runs on both CPU and GPU.
7. TensorFlow
TensorFlow is a product of the Google Brain Team, which has come together to develop machine learning and is in too much demand among data scientists and machine learning engineers. It’s a software library for numerical computing and built for everyone from beginners to an expert. It allows ones to access the power of deep learning without having to understand some of the complicated principles behind it and is among the data science tools that help make deep learning accessible to thousands of companies.
8. Matplotlib
Matplotlib is the most popular data science tool for beginners used for plotting. Many other popular plotting libraries depend on the matplotlib API, including the pandas plotting function and Seaborn.
Matplolib is a rich plotting library that includes functions for creating various graphs and visualizations. Additionally, it has features for creating animated and interactive charts.
9. Jupyter Notebooks
Jupyter notebooks are a very popular data science tool in 2022 and are in great demand for data science beginners. These provide an interactive Python programming interface. The advantage of writing Python in a notebook environment is that it lets you quickly render visualizations, datasets, and data summaries directly in the program.
10. Gawk
Gawk is an open source rendition of awk, which is the specific reason for a programming language used for working with documents. Awk has one of the huge components of the Unix framework. Gawk is a GNU utility that makes it easy to make changes to textual records and allows clients to extract information and generate reports.
11. Weka
Weka is AI programming written in Java at the University of Waikato. It is used for data mining and allows clients to work with huge arrays of data. The Weka highlights section includes preprocessing, ordering, regression, clustering, trials, workflow, and visualization. However, it needs advanced utility in contrast to R and Python, which is why it is not as widely used in experienced settings.
12.Scala
Scala runs on the Java platform. It is exceptional for huge datasets and is generally used with big data engines like Apache Spark and Apache Kafka. This useful programming style brings speed and greater efficiency, which has led to it being adopted by a growing number of organizations as a core part of their data science toolkit.
13. SQL
Structured Query Language (SQL) is a specific programming language reason for information stored in relational datasets, and it is high on demand data science tool in 2022. SQL is used for more fundamental data analysis and can perform operations such as arranging and manipulating data or retrieving data from a dataset. Since SQL has been used by associations for quite a long time, data scientists can take advantage of the already existing huge body of SQL. Among information science tools, it ranks as truly excellent at sifting and selecting datasets.
14. RapidMiner
RapidMiner is an insightful investigation tool with visualization and statistical demonstration capacities. The basis of the product that is RapidMiner Studio is a free and open-source platform. The organization also provides additional enterprise-level items that can be purchased to enhance the base platform.
15. Apache Hadoop
The Apache Hadoop programming library is a system written in Java for preparing huge and complex datasets. The core modules of the Apache Hadoop framework include Hadoop Common, Hadoop MapReduce, Hadoop Yarn, and Hadoop Distributed File System (HDFS).
16. Apache Spark
Apache Spark is a group of figural frameworks for data analysis. It has been shipped in huge associations for its enormous information capabilities associated with effortless utilization. It was originally developed as Spark at the University of California, and later the source code was bought by the Apache Foundation so it could be free forever. It is often favored over other big data tools because of its speed.
17. Orange
Orange is one of the in-demand tools among data science tools. It is a powerful tool to perform data analysis and visualization, see data flow, and become more productive. It allows clients to dissect and visualize data without coding. This makes machine learning a good choice for beginners.
18. Axis
Axiis is a lesser-known data visualization system among data science tools. It allows clients to create graphs and explore data using pre-built parts expressively and concisely.
19. Impala
Impala is an MPP-SQL (Massive Parallel Processing) query engine for processing large amounts of data stored in Hadoop clusters. This is open-source software written in C ++ and Java. It offers high performance and low latency compared to other Hadoop SQL engines.
In other words, Impala is the most powerful SQL engine (with an RDBMS-like experience) and provides the fastest way to access the data stored in the Hadoop distributed file system.
20. Apache Drill
Apache Drill is an open-source variant of Google’s Dremel for intelligently querying huge data sets. It is incredible, adaptable, and nimble, supports information stored in various configurations in documents or NoSQL datasets, and is perhaps the most flexible tool for data science.
