Introduction

In this paper, we explore the potential of large intelligent surfaces (LIS) to enable new ways of communication and interaction with the physical world. LIS are composed of a large number of small sensing and computing units that can be distributed over a large area to sense, process and actuate in response to the environment. We focus on two key challenges in realizing the vision of LIS: (i) efficient sensing and (ii) robustness to dynamic changes in the environment.

We show how compressive sensing (CS) can be used for efficient sensing of signals scattered in space, such as those emanating from a user’s body. We demonstrate how CS can be used to design LIS that are less resource-intensive than traditional approaches, while still providing accurate estimates of the desired signal. We also show how deep learning can be used to improve the robustness of LIS to dynamic changes in the environment, such as occlusions and clutter. We present several experimental results that demonstrate the effectiveness of our approach in both indoor and outdoor environments.

What is Large Intelligent Surface?

According to recent studies, Large Intelligent Surfaces (LIS) are becoming increasingly important in a wide variety of applications such as Internet of Things (IoT), 5G communications, and beyond. A LIS is a surface that can be used to collect and process information. In other words, it is a surface that can be used to collect and process information. In general, a LIS is composed of an array of sensors, which can be used to collect data about the surrounding environment. In addition, a LIS can also be equipped with computing resources, which can be used to process the collected data.

The ability to collect and process data about the surrounding environment makes LISes very powerful tools for a wide variety of applications. For example, LISes can be used to monitor the traffic in a city, or to track the movement of people in a building. In addition, LISes can also be used for security purposes, such as detecting intruders in a building or area.

One of the challenges in implementing LISes is how to design the sensor array and algorithms needed to collect and process the data collected by the sensors. This challenge is addressed by compressive sensing and deep learning. Compressive sensing is a technique that can be used to reduce the number of sensors needed to collect data about a given scene. Deep learning is a machine learning technique that can be used to learn how to process the data collected by sensors. Together, these two techniques can be used to enable LISes with reduced sensor requirements and improved data processing capabilities.

What is Compressive Sensing?

Compressive Sensing is a technique for reducing the number of measurements needed to acquire an image, by using the sparsity of the image in some transform domain.

This is achieved by sensing only a small subset of the samples in the image, and reconstructing the full image from this subset using optimization methods. The basis for this approach is that most natural images are sparse or compressible in some transform domain, i.e., they can be represented with few non-zero coefficients in some basis.

This means that they can be accurately represented with far fewer measurements than there are pixels, if we choose our measurement process and reconstruction algorithm wisely.

How can Compressive Sensing be used for Large Intelligent Surfaces?

Compressive Sensing (CS) is a relatively new area of study that has shown great promise for a variety of applications. In particular, CS has been shown to be very effective for problems that involve sensing and reconstructing signals that are very high-dimensional and/or have a very large number of degrees of freedom. One example of such a problem is that of Large Intelligent Surfaces (LISs), which are large, two-dimensional surfaces that are covered with sensors and/or other types of active devices.

LISs are becoming increasingly common as the technology for making them becomes more accessible and as the need for more “intelligent” environments grows. For example, LISs are being used in buildings to provide better lighting control, energy efficiency, and user comfort; in automobiles to improve safety and fuel efficiency; and in aircraft to reduce weight and increase flight safety. CS has been shown to be an effective tool for LIS applications because it can help reduce the amount of data that needs to be collected and processed, while still providing accurate results.

There are two main ways in which CS can be used for LIS applications: 1) by using CS to directly sense and reconstruct signals from the surface, or 2) by using CS as part of a larger system that includes other methods, such as Deep Learning (DL), to sense and reconstruct signals from the surface. The first approach is typically more efficient in terms of computational resources, while the second approach is typically more accurate.

What is Deep Learning?

Deep learning is a subset of machine learning that uses algorithms to model high-level abstractions in data. By doing this, deep learning can enable computers to make predictions or perform tasks that are difficult or impossible for humans to do.

How can Deep Learning be used for Large Intelligent Surfaces?

Deep learning has been shown to be effective for various intelligent surface applications such as image recognition, object detection, and facial recognition. In this paper, we focus on how compressive sensing can be used to enable deep learning for large intelligent surfaces. Compressive sensing is a technique that allows for data acquisition and compression while still preserving the information content of the original data. This makes it possible to use deep learning algorithms on large intelligent surfaces without having to sacrifice processing power or storage space. We demonstrate how compressive sensing can be used to enable deep learning for a large intelligent surface by using a convolutional neural network to classify images acquired by a compressive sensor. We show that the use of compressive sensing can reduce the amount of data that needs to be processed by the convolutional neural network by up to 50%, while still allowing for accurate classification of the images.

Benefits of using Large Intelligent Surfaces

A Large Intelligent Surface (LIS) is a smart, connected surface that can interact with devices and people. LIS technology has the potential to revolutionize the way we interact with our surroundings.

There are many potential benefits of using Large Intelligent Surfaces. For example, LIS technology could be used to create interactive public spaces, such as parks and museums. LIS surfaces could also be used in homes and businesses to create smart environments that are tailored to the needs of the occupants.

LIS technology can also be used to improve the efficiency of energy use in buildings. For example, LIS surfaces could be used to passively collect solar energy and convert it into electricity. LIS surfaces could also be used to monitor and optimize the use of HVAC systems in buildings.

In addition, LIS technology can be used to improve communication and transportation systems. For example, LIS surfaces could be used to create dynamic maps that show real-time traffic conditions. LIS surfaces could also be used to create more efficient antennas for cellular networks.

Applications of Large Intelligent Surfaces

Applications of Large Intelligent Surfaces (LISs) are many and varied. They can be used for intercepted communications, sensing, reflection, and even power generation and storage. LISs can provide significant advantages over traditional methods in all of these areas.

Compressive sensing (CS) is a technique for reconstructing signals from a small number of measurements. CS has been shown to be particularly effective for high-dimensional signals, such as those that arise in LIS applications. Deep learning is a powerful tool for extracting features from high-dimensional data. Combined, CS and deep learning can enable LISs to achieve their full potential.

This paper describes the application of CS and deep learning to LISs. We demonstrate how CS can be used to reduce the number of measurements required for LIS applications. We also show how deep learning can be used to extract features from the measured data, resulting in improved performance. Finally, we discuss how these techniques can be used together to enable new applications of LISs.

Challenges of Large Intelligent Surfaces

There are many challenges associated with Large Intelligent Surfaces (LISs), including their size, complexity, and the need to process and transmit large amounts of data. In addition, LISs are often located in difficult-to-reach or dangerous areas, making them difficult to deploy and maintain.

Compressive sensing (CS) is a promising approach for reducing the data requirements of LISs. CS relies on the fact that many signals are sparse or compressible, meaning that they can be represented using far fewer samples than traditional methods. This reduces the data requirements of LISs, making them more practical to deploy.

Deep learning is another promising approach for reducing the data requirements of LISs. Deep learning algorithms can learn from data with far fewer labels than traditional machine learning algorithms, making them well suited for the unstructured and often unlabeled data found in LISs.

By combining CS and deep learning, it is possible to build LISs that are both practical and effective. This combination of techniques has the potential to enable a new generation of smart buildings, cities, and Infrastructure-as-a-Service (IaaS) platforms.

Future of Large Intelligent Surfaces

As the world increasingly moves towards a digital future, the need for large intelligent surfaces (LIS) that can interact with humans and devices is becoming more and more apparent. LIS are defined as physical surfaces that can sensing and computing capabilities to detect, analyze, and respond to the presence of people and objects. While the concept of an LIS is not new, the technology to create them has only recently become available.

Compressive sensing is a relatively new field that deals with the acquisition and reconstruction of signals that are too complex to be handled by traditional methods. Deep learning is a type of machine learning that uses artificial neural networks to learn from data in a way that is similar to the way humans learn. By combining these two technologies, it is possible to create LIS that are able to detect the presence of people and objects, and respond accordingly.

There are a number of potential applications for LIS, including in homes, office buildings, public spaces, and vehicles. In the home, an LIS could be used to turn on lights when someone enters a room or to adjust the temperature based on the number of people in a room. In office buildings, LIS could be used to direct people to available meeting rooms or open workspaces. In public spaces, LIS could be used to provide information about nearby attractions or events. In vehicles, LIS could be used to provide real-time traffic information or route directions.

The possibilities for LIS are endless, and as the technology continues to develop, we can only imagine what new and exciting applications will be made possible in the future.
