There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

Machine Learning is the study of methods for programming computers to learn. Computers are applied to a wide range of tasks, and for most of these it is relatively easy for programmers to design and implement the necessary software. However, there are many tasks for which this is difficult or impossible. These can be divided into four general categories. First, there are problems for which there exist no human experts. For example, in modern automated manufacturing facilities, there is a need to predict machine failures before they occur by analyzing sensor readings. Because the machines are new, there are no human experts who can be interviewed by a programmer to provide the knowledge necessary to build a computer system. A machine learning system can study recorded data and subsequent machine failures and learn prediction rules. Second, there are problems where human experts exist, but where they are unable to explain their expertise. This is the case in many perceptual tasks, such as speech recognition, hand-writing recognition, and natural language understanding. Virtually all humans exhibit expert-level abilities on these tasks, but none of them can describe the detailed steps that they follow as they perform them. Fortunately, humans can provide machines with examples of the inputs and correct outputs for these tasks, so machine learning algorithms can learn to map the inputs to the outputs. Third, there are problems where phenomena are changing rapidly. In finance, for example, people would like to predict the future behavior of the stock market, of consumer purchases, or of exchange rates. These behaviors change frequently, so that even if a programmer could construct a good predictive computer program, it would need to be rewritten frequently. A learning program can relieve the programmer of this burden by constantly modifying and tuning a set of learned prediction rules. Fourth, there are applications that need to be customized for each computer user separately. Consider, for example, a program to filter unwanted electronic mail messages. Different users will need different filters. It is unreasonable to expect each user to program his or her own rules, and it is infeasible to provide every user with a software engineer to keep the rules up-to-date. A machine learning system can learn which mail messages the user rejects and maintain the filtering rules automatically. Machine learning addresses many of the same research questions as the fields of statistics, data mining, and psychology, but with differences of emphasis. Statistics focuses on understanding the phenomena that have generated the data, often with the goal of testing different hypotheses about those phenomena. Data mining seeks to find patterns in the data that are understandable by people. Psychological studies of human learning aspire to understand the mechanisms underlying the various learning behaviors exhibited by people (concept learning, skill acquisition, strategy change, etc.).

The organization of behavior: A neuropsychological theory

In this paper, we propose a coalitional game theoretic approach to the power control problem in resourceconstrained wireless sensor networks, where the objective is to enhance power efficiency of individual sensors while providing the QoS requirements. We model this problem as two-sided one-to-one matching game and deploy deferred acceptance procedure that produces a single matching in the core, which is the set of actions aN of all sensors such that no coalition of sensors has an action that all its members prefer to aN. Furthermore, we show that, by applying the procedure repeatedly, a certain stable state is achieved where no sensor can anticipate improvements in their power efficiency as far as all of them are subject to their own QoS constraints. We evaluate our proposal by comparing them with cluster-based coalescing and the local optimal solution obtained by maximizing the total system energy efficiency, where the objective function is non-convex.

Power control for mission critical wireless sensor networks using repeated coalitional games

In cardiac pacemaker design, energy expenditure is an important issue. This work aims to explore whether varying stimulation pulse configuration is a viable optimization strategy for reducing energy consumption by the pacemaker. A single cardiomyocyte was used as an experimental model. Each cardiomyocyte was stimulated with different stimulation protocols using rectangular waveforms applied in varying number, in short succession. The amplitude, the width of each pulse, and the interval between consecutive pulses were modified. The application of multiple pulses in a short sequence led to a reduction of the threshold voltage required for stimulation when compared to a single pulse. However, none of the employed multi-pulse sequences reduced the overall energy expenditure of cell stimulation when compared to a single pulse stimulation. Among multiple pulse protocols, a combination of two short pulses (1 ms) separated with a short interval (0.5 ms) had the same energy requirements as a single short pulse (1 ms), but required the application of significantly less voltage. While increasing the number of consecutive pulses does not reduce the energy requirements of the pacemaker, the reduction in threshold voltage can be considered in practice if lower stimulation voltages are desired.

Energy-efficiency of Cardiomyocyte Stimulation with Rectangular Pulses

Molecular motor communication (MMC) is a class of walkway based molecular communication, which is realized through motor proteins. In MMC, chemical energy is converted into the mechanical transport of molecules on cellular tracks named microtubules. In this paper, a channel propagation model of MMC nanonetworks is proposed, capturing the stochastic nature of molecular motors, transport bidirectionality, chemical energy conversion, and the topology of microtubules. Closed-form expressions of the probability of presence, delay, and attenuation are derived. The results are validated against Markov Chain Monte-Carlo simulations. Unlike diffusion-based and flow-based communication, MMC is active, low-delay, bidirectional, controllable, and can carry significantly large molecules. These characteristics make MMC an ideal candidate for realizing nanonetworks.

The tremendous advances in radio communications and ultra-low power (ULP) electronics have enabled the development of communicating biomedical sensors for the continuous monitoring of patients' physiological signals. In the last decade, much research has been done towards the advancement of wireless body area network (WBAN) technology, resulting in the release of the IEEE 802.15.6-2012 standard for the interconnection of wearable and implantable biomedical sensors. This chapter provides an overview of the sets of wireless body sensor network (WBSN) applications, as well as of their characterization parameters. One of the key requirements for widespread adoption of the WBSN technology for daily healthcare is, however, the ease of use of the sensing devices. From the patient's perspective, this means that besides being small, unobtrusive and ergonomic, WBAN nodes have to be capable of long-term operation without the need to frequently charge, recharge or even use batteries. Although the recent advances in ULP electronics have reduced the power consumption of major WBSN node components to the sub-milliwatt (sub-mW) level, the vision for uninterrupted self-powered WBANs has yet to be realized. Energy harvesting (EH), i.e. taking energy from ambient sources to power autonomous wireless networked systems, is a developing technology with a tremendous potential to complement ULP electronics towards the realization of this vision, thereby enabling the perpetual remote monitoring of a patient's vital signs. An integrated circuit (IC) that integrates most of network functionalities onto low power wearable systems has been introduced as well.
