Multi-agent pre-trade analysis acceleration in FPGA

Abstract

Background: Cognitive Muscular TherapyTM (CMT) is an integrated behavioural intervention developed for knee osteoarthritis. CMT teaches patients to reconceptualise the condition, integrates muscle biofeedback and aims to reduce muscle overactivity, both in response to pain and during daily activities. This nested qualitative study explored patient and physiotherapist perspectives and experiences of CMT.Methods: Five physiotherapists were trained to follow a well-defined protocol and then delivered CMT to at least two patients with knee osteoarthritis. Each patient received seven individual clinical sessions and was provided with access to online learning materials incorporating animated videos. Semi-structured interviews took place after delivery/completion of the intervention and data were analysed at the patient and physiotherapist level.Results: Five physiotherapists and five patients were interviewed. All described a process of changing beliefs throughout their engagement with CMT. A framework with three phases was developed to organise the data according to how osteoarthritis was conceptualised and how this changed throughout their interactions with CMT. Firstly, was an identification of pain beliefs to be challenged and recognition of how current beliefs can misalign with daily experiences. Secondly was a process of challenging and changing beliefs, validated through new experiences. Finally, there was an embedding of changed beliefs into self-management to continue with activities. Conclusion:This study identified a range of psychological changes which occur during exposure to CMT. These changes enabled patients to reconceptualise their condition, develop a new understanding of their body, understand psychological processes, and make sense of their knee pain.

A FAST Hardware Decoder Optimized for Template Features to Obtain Order Book Data in Low Latency

“…This is due to the introduction of new technologies in the financial market, impacting its buying and selling mechanism, which buyers need to find sellers as quickly and efficiently as possible and vice versa. For this reason, several techniques have been developed in order to identify the best trading opportunities, such as mathematical and artificial intelligence models (GERLEIN et al, 2014), as well as acceleration techniques. Another technique used to mitigate the latency is the use of general-purpose processors with specialized Network Interface Controller (NIC) (BOUTROS et al, 2017).…”

Efficiency analysis methodology of FPGAs based on lost frequencies, area and cycles

“…FPGAs are used for HPC in several domains, such as bioinformatics [2], linear algebra [3], stock market analysis [4] and image processing. It is shown that FPGAs can provide significant speedups in these domains [1].…”

Network on Chip Architecture for Multi-Agent Systems in FPGA

“…In contrast to bus-based architectures, NoCs route packets of data from the source to the destination components, via a network fabric that consists of switches (routers) and interconnection links (wires). The model proposed in this paper uses the Event Driven Reactive Architecture (EDRA) introduced in [Gerlein et al 2014a] and posteriorly in [Gerlein et al 2014b], to design and implement the agents at individual level, while also implementing a hierarchical Star-NoC at social level to enable agents to communicate, cooperate and scale.…”

“…For informative events, four types of ports are defined: (a) Communication Reception Port (ComRx) -handles incoming information from inside the system; (b) External input -handles incoming information from an external source; (c) Communication Transmission Port (ComTx) -handles outgoing information inside the system; (d) External output -used to send data or information to an external destination. For a more detailed description of the EDRA we reffer the autor to [Gerlein et al 2014a] and [Gerlein et al 2014b]. …”

“…To validate the proposed concept, a MAS comprised successively of 5, 30, 150 and 375 agents has been deployed in an Altera's Stratix IV FPGA to simulate intensive interactions in a generic agent-based application. For the experiments, a router microarchitecture is designed, as well as the OCP interfaces at the nodes to integrate the Event Driven Reactive Architecture (EDRA) [Gerlein et al 2014a] [Gerlein et al 2014b] with the NoC's interconnection fabric. Results have shown a zero load latency of seven clock cycles per hop and a high throughput of 1.6 Gbps represented by the injection of messages to the nodes every three clock cycles at full-load capacity.…”
