18 Jun 2017TL;DR: In this work, a defect rescuing design is proposed to restore the computation accuracy of memristor-based synaptic network and can recover almost its full performance when 20% random defects are present.
Abstract: Memristor-based synaptic network has been widely investigated and applied to neuromorphic computing systems for the fast computation and low design cost. As memristors continue to mature and achieve higher density, bit failures within crossbar arrays can become a critical issue. These can degrade the computation accuracy significantly. In this work, we propose a defect rescuing design to restore the computation accuracy. In our proposed design, significant weights in a specified network are first identified and retraining and remapping algorithms are described. For a two layer neural network with 92.64% classification accuracy on MNIST digit recognition, our evaluation based on real device testing shows that our design can recover almost its full performance when 20% random defects are present.

28 Aug 2001TL;DR: In this paper, a user-wearable electronic wireless transaction apparatus is described, which consists of a housing which houses a wireless communication device, one or more electronic circuits, a power source, a display device and a biometric data reading device.
Abstract: A user-wearable electronic wireless transaction apparatus is disclosed. The user-wearable electronic wireless transaction apparatus comprises a housing which houses a wireless communication device, one or more electronic circuits, a power source, a display device and a biometric data reading device. While enabled as a timepiece or performing other functions suitable to a user-wearable apparatus, the apparatus can establish wireless communication with a counterpart communication apparatus in order to conduct a transaction. The biometric data reading device can read the user's applicable biometric data and then transmit a user identity validation and the wireless communication device can transmit user authorization for the transaction.

TL;DR: Using high-resolution optical reflectometry, group index and physical thickness can both be determined by precisely measuring optical time delays through a sample as mentioned in this paper, which offers both the high-spatial resolution and large dynamic range required to perform accurate measurements using this technique.

TL;DR: A set of rules for the transfer of control is applied to 4 sets of dialogues and it is found that both allocation of control and the manner in which control is transferred is radically different for the two dialogue types.
Abstract: Conversation between two people is usually of mixed-initiative, with control over the conversation being transferred from one person to another. We apply a set of rules for the transfer of control to 4 sets of dialogues consisting of a total of 1862 turns. The application of the control rules lets us derive domain-independent discourse structures. The derived structures indicate that initiative plays a role in the structuring of discourse. In order to explore the relationship of control and initiative to discourse processes like centering, we analyze the distribution of four different classes of anaphora for two data sets. This distribution indicates that some control segments are hierarchically related to others. The analysis suggests that discourse participants often mutually agree to a change of topic. We also compared initiative in Task Oriented and Advice Giving dialogues and found that both allocation of control and the manner in which control is transferred is radically different for the two dialogue types. These differences can be explained in terms of collaborative planning principles.

TL;DR: The results show that the Minnesota functionals, M05, M06, and M06-L give the best performance for the two diverse databases, which suggests that they deserve more attention for applications to catalysis.
Abstract: Thirty four density functional approximations are tested against two diverse databases, one with 18 bond energies and one with 24 barriers. These two databases are chosen to include bond energies and barrier heights which are relevant to catalysis, and in particular the bond energy database includes metal-metal bonds, metal-ligand bonds, alkyl bond dissociation energies, and atomization energies of small main group molecules. Two revised versions of the Perdew–Burke–Ernzerhof (PBE) functional, namely the RPBE and revPBE functionals, widely used for catalysis, do improve the performance of PBE against the two diverse databases, but give worse results than B3LYP (which denotes the combination of Becke's 3-parameter hybrid treatment with Lee–Yang–Parr correlation functional). Our results show that the Minnesota functionals, M05, M06, and M06-L give the best performance for the two diverse databases, which suggests that they deserve more attention for applications to catalysis. We also obtain notably good performance with the τ-HCTHhyb, ωB97X-D, and MOHLYP functional (where MOHLYP denotes the combination of the OptX exchange functional as modified by Schultz, Zhao, and Truhlar with half of the LYP correlation functional).
