The observers' paradox: apparent computational complexity in physical systems
نویسندگان
چکیده
Many researchers in AI and cognitive science believe that the complexity of a behavioral description reflects the underlying information processing complexity of the mechanism producing the behavior. This paper explores the foundations of this complexity argument. We first distinguish two types of complexity judgements that can be applied to these descriptions and then argue that neither type can be an intrinsic property of the underlying physical system. In short, we demonstrate how changes in the method of observation can radically alter both the number of apparent states and the apparent generative class of a system's behavioral description. From these examples we conclude that the act of observation can suggest frivolous computational explanations of physical phenomena, up to and including cognition. The Observers’ Paradox 3 The daily warmth we experience, my father said, is not transmitted by Sun to Earth but is what Earth does in response to Sun. Measurements, he said, measure measuring means.1

The Paradox of Intervening in Complex Adaptive Systems; Comment on “Using Complexity and Network Concepts to Inform Healthcare Knowledge Translation”
This commentary addresses two points raised by Kitson and colleagues’ article. First, increasing interest in applying the Complexity Theory lens in healthcare needs further systematic work to create some commonality between concepts used. Second, our need to adopt a better understanding of how these systems organise so we can change the systems overall behaviour, creates a paradox. We seek to m...
متن کاملTrouton-Noble paradox revisited
An apparent paradox is obtained in all previous treatments of the Trouton-Noble experiment; there is a three-dimensional (3D) torque T in an inertial frame S in which a thin parallel-plate capacitor is moving, but there is no 3D torque T in S, the rest frame of the capacitor. Different explanations are offered for the existence of another 3D torque, which is equal in magnitude but of opposite d...
متن کاملDistance-Aware Beamforming for Multiuser Secure Communication Systems
Typical cryptography schemes are not well suited for low complexity types of equipment, e.g., Internet of things (IoT) devices, as they may need high power or impose high computational complexity on the device. Physical (PHY) layer security techniques such as beamforming (in multiple antennas systems) are possible alternatives to provide security for such applications. In this paper, we consid...
متن کاملIncreasing the Performance of OFDM Systems by PAPR Reduction in PTS Technique using Election Optimization Algorithm
Orthogonal Frequency Division Multiplexing (OFDM) is a useful technology in wireless communications that provides high-rate data transmission in multipath fading channels. The advantages of OFDM systems are the high spectral efficiency and strong resistance to frequency selective fading. In OFDM systems, a large number of sub-carriers are used to modulate the symbols causing the time-domain OFD...

A low complexity dynamic subcarrier and power allocation methodology for downlink communication in an OFDM-based multiuser environment is developed. The problem of maximizing overall capacity with constraints on total power consumption, bit error rate and data rate proportionality among users requiring different QOS specifications is formulated. Assuming perfect knowledge of the instantaneo...
