AI and data analytics put a previously near-impossible task within reach: helping decision-makers efficiently analyze vast amounts of data and swiftly arrive at a set of potential actions.

It then rapidly develops multiple courses of action, which could include maneuvering, countermeasures, or engaging in offensive or defensive activities. Using machine learning, the system sifts through many possible courses of action, taking into account interrelated consequences and downstream implications. Operators and commanders then receive a timely menu of optimized choices, which accelerates command-and-control decision-making and strengthens space defense in mission-critical situations. In response to commercial demands for global communication and data transport, satellite constellations and the networks that connect them are becoming larger and more complex.

These networks are also becoming increasingly vulnerable to increasingly sophisticated kinetic and non-kinetic threats. By adopting AI into space systems, operators can mitigate these threats and make space networks and constellations more resilient.

Organizations can use AI to quickly scan through data to recognize network vulnerabilities. Organizations can also embed self-learning algorithms into the satellites themselves, to make them more self-sufficient and more resilient if up-link and down-link communications with ground operations are lost. Automating such tasks on satellites themselves can accelerate these actions and free operators to concentrate on more complex, mission-critical work. As with any application of a new technology, in space or elsewhere, security and trust are paramount to adoption and effectiveness. AI security begins with the development of the AI algorithms.

Organizations must ensure the pedigree of the data used to train the algorithms, ensure that algorithms are developed with as little bias as possible, and maintain security throughout the software development process and data storage. Additionally, organizations with space assets and systems will need to train operators in AI and machine learning, which includes an understanding of how AI systems are built and designed. Operators must also have a complete understanding of the capabilities and limitations of their AI-powered solutions.

Only through comprehensive training and education, as well as implementing secure processes, will operators and decision-makers trust AI systems enough to use them to enhance their missions. As the space environment rapidly evolves and proliferates with new users, new capabilities, and increasingly sophisticated threats, deterring and defending our space assets has become both an imperative for national security and a far more complicated task. Through improving space domain awareness, accelerating command-and-control decisions, making satellites and their networks more resilient, and more, AI solutions offer a transformative opportunity for protecting, improving, and enhancing space missions and helping the United States maintain space dominance.

Revolutionizing IoT through AI has indeed helped in saving many lives. The concept of a smart factory is centering around AIoT and digital transformation. Predictive Maintenance is one of the main attractions of AIoT. It helps machines to identify themselves when they need maintenance or repair. The trouble of unexpected machine failure is no longer a problem.

So with AIoT, uninterrupted production becomes a reality. It can reduce maintenance and breakdown costs. It also helps in manufacturing goods in quantities according to the market demand. The owners can track the movement of the products and raw materials with the help of IoT sensors. AIoT has indeed given a hi-tech face to the manufacturing sector. Like other industries, the agriculture sector has also become smart with the impact of AI and IoT. The automation in irrigation, fertilization, harvesting, and other production processes, have made the expenses come down a lot. With the help of AIoT, the quality and quantity of the harvest are predictable.

It helps in the better management of the entire process and also leads to higher quality output. More accurate climate predictions also help the farmers to be in better control. Weather forecasting has become more efficient and accurate with the help of AIoT. With more precise high-resolution remote sensors, forecasting has become more dependable.

It can help the airplanes to navigate easily; it can predict wildfires or possible fire breakouts. Advance information about these can help in more efficient service. As mentioned above, it can also help the agriculture sector. Accurate forecasting can also help construction companies, as they can plan their construction activities. But now it is everywhere. In the future, we will see the rise of more intelligent gadgets, and IoT app development will flourish more.

AIoT will open an arena of new opportunities and business ideas. We also summarize some contributions and case studies from the industry. Then, the project was donated to the Apache Software Foundation in Several research projects have made essential contributions for building and improving Spark core and the main upper-level libraries [ 7 , 33 , 61 , 83 , 89 , 90 , 93 — 95 ]. Footnote 8 Later, it became a part of the Apache Spark project since version 0. Many packages Footnote 9 have also been contributed to Apache Spark from both academia and industry.

Furthermore, the creators of Apache Spark founded Databricks, Footnote 10 a company which is closely involved in the development of Apache Spark. It is evolving rapidly with changes to its core APIs and addition of upper-level libraries. Its core data abstraction, the Resilient Distributed Dataset RDD , opens the door for designing scalable data algorithms and pipelines with better performance.

While RDD was the main abstraction introduced in Spark 1. Moreover, a major release Spark 2. As a framework, it combines a core engine for distributed computing with an advanced programming model for in-memory processing. Although it has the same linear scalability and fault tolerance capabilities as those of MapReduce, it comes with a multistage in-memory programming model comparing to the rigid map-then-reduce disk-based model.

With such an advanced model, Apache Spark is much faster and easier to use. It is also considered as a general-purpose engine that goes beyond batch applications to combine different types of computations e.

Previous data flow frameworks lack such data sharing ability although it is an essential requirement for different workloads [ 90 ]. As the next-generation engine for big data analytics, Apache Spark can alleviate key challenges of data preprocessing, iterative algorithms, interactive analytics and operational analytics among others. With Apache Spark, data can be processed through a more general directed acyclic graph DAG of operators using rich sets of transformations and actions.

It automatically distributes the data across the cluster and parallelizes the required operations. It supports a variety of transformations which make data preprocessing easier especially when it is becoming more difficult to examine big datasets.

On the other hand, getting valuable insights from big data requires experimentation on different phases to select the right features, methods, parameters and evaluation metrics. Apache Spark is natively designed to handle such kind of iterative processing which requires more than one pass over the same dataset e. Moreover, Apache Spark is not only a unified engine for solving different data problems instead of learning and maintaining several different tools, but also a general-purpose framework which shortens the way from explanatory analytics in the laboratory to operational analytics in production data applications and frameworks [ 70 ].

Consequently, it can lead to a higher analyst productivity, especially when its upper-level libraries are combined to implement complex algorithms and pipelines. Since its initial releases, Apache Spark has seen a rapid adoption by enterprises across a wide range of industries. Footnote 11 Such fast adoption with the potential of Apache Spark as a unified processing engine, which integrates with many storage systems e.
