Recognition HW 1

چکیده
This paper gave an estimate of processing time for fast visual categorization of animals. While subjects were asked to decide whether a 20-msec flashed natural photograph contains an animal, differential event-related potential (ERP) activity between target trials and distractor trials was observed in frontal recording sites at around 150 msec after stimulus onset. The authors thus claimed that this differential response should rise once necessary visual processing has been completed, and that such rapid visual categorization could mainly rely on feedforward mechanisms. These claims, however, are arguable due to the following issues in their hypothesis and experimental design.

Gesture Recognition Using Neural Networks Based on HW/SW Cosimulation Platform
Hardware/software (HW/SW) cosimulation integrates software simulation and hardware simulation simultaneously. Usually, HW/SW co-simulation platform is used to ease debugging and verification for very large-scale integration (VLSI) design. To accelerate the computation of the gesture recognition technique, an HW/SW implementation using field programmable gate array (FPGA) technology is presented...
متن کاملInsulator protein Su(Hw) recruits SAGA and Brahma complexes and constitutes part of Origin Recognition Complex-binding sites in the Drosophila genome
Despite increasing data on the properties of replication origins, molecular mechanisms underlying origin recognition complex (ORC) positioning in the genome are still poorly understood. The Su(Hw) protein accounts for the activity of best-studied Drosophila insulators. Here, we show that Su(Hw) recruits the histone acetyltransferase complex SAGA and chromatin remodeler Brahma to Su(Hw)-dependen...
متن کاملA New Approach to Design Reliable Real-Time Speech Recognition Systems
Hereafter, we propose a novel approach that couples HW/SW codesign with redundancy techniques to implement speech recognition systems (SRS). Due to the specific characteristics of digital signal processing (DSP) algorithms, these systems deserve special attention when partitioning the HW and SW parts. Also, in many applications like voice-oriented bank transactions or security systems, the need...
متن کاملAge-Related Evolution Patterns in Online Handwriting
Characterizing age from handwriting (HW) has important applications, as it is key to distinguishing normal HW evolution with age from abnormal HW change, potentially triggered by neurodegenerative decline. We propose, in this work, an original approach for online HW style characterization based on a two-level clustering scheme. The first level generates writer-independent word clusters from raw...
متن کاملK-means clustering algorithm for multimedia applications with flexible HW/SW co-design
In this paper, we report a hardware/software (HW/SW) co-designed K-means clustering algorithm with high flexibility and high performance for machine learning, pattern recognition and multimedia applications. The contributions of this work can be attributed to two aspects. The first is the hardware architecture for nearest neighbor searching, which is used to overcome the main computational cost...
متن کاملHW-Hume in Isabelle
HW-Hume is the decidable Hume level oriented to direct implementation in hardware. As a first stage in the development of a verified compiler from HW-Hume to Java, we have implemented the semantics of HW-Hume in the Isabelle/HOL theorem prover, enabling the automatic proof of correctness of programs in a Floyd/Hoare style.
