Incremental Few-Shot Object Detection

Abstract: Existing object detection methods typically rely on the availability of abundant labelled training samples per class and offline model training in a batch mode. These requirements substantially limit their scalability to open-ended accommodation of novel classes with limited labelled training data, both in terms of model accuracy and training efficiency during deployment. We present the first study aiming to go beyond these limitations by considering the Incremental Few-Shot Detection (iFSD) problem setting, where new classes must be registered incrementally (without revisiting base classes) and with few examples. To this end we propose OpeN-ended Centre nEt (ONCE), a detector designed for incrementally learning to detect novel class objects with few examples. This is achieved by an elegant adaptation of the efficient CentreNet detector to the few-shot learning scenario, and meta-learning a class-wise code generator model for registering novel classes. ONCE fully respects the incremental learning paradigm, with novel class registration requiring only a single forward pass of few-shot training samples, and no access to base classes – thus making it suitable for deployment on embedded devices, etc. Extensive experiments conducted on both the standard object detection (COCO, PASCAL VOC) and fashion landmark detection (DeepFashion2) tasks show the feasibility of iFSD for the first time, opening an interesting and very important line of research.

Method and apparatus for managing lists using multi-touch

Abstract: A list managing method and apparatus that manage a list of content in a portable terminal having a touch screen according to multi-touch signals are disclosed. The method includes: detecting multi-touch signals input to a list on a touch screen; determining whether the multi-touch signals are input for a period of time equal to or greater than an activation time period; designating, if the multi-touch signals are input within the activation time period, the entire list with a selection area for altering a structure of a list; identifying a gesture generated by the multi-touch signals; expanding or contracting the structure of the entire list according to the gesture; and displaying the altered structure of the entire list on the touch screen.

An edge contact type cell for Phase Change RAM featuring very low power consumption

Abstract: In this paper, the Phase Change Random Access Memory (PRAM, also known as Ovonic Unified Memory-OUM) cell, which has an extremely small and reproducible contact area and improved thermal environment, was fabricated and electrically characterized. The memory cell successfully operates with 30 ns pulses of 0.20 mA for RESET (high resistive) state and 0.13 mA for SET (low resistive) state. This is the best record of the published data.

Battery charging method and electronic device

Abstract: A battery charging method comprises providing power from a battery to an external device using a first circuit and receiving power from a first power source to provide power to the battery using a second circuit while providing power to the external device, wherein providing the power from the battery comprises providing the power from the battery based on determining that the external device is connected to the electronic device.

Electrochemical properties and thermal stability of LiaNi1-xCoxO2 cathode materials

Abstract: Conductive and electrochemical properties as well as thermal stability of Li{sub a}Ni{sub 1{minus}x}Co{sub x}O{sub 2} where x = 0--0.3 and a = 1.0--0.4 have been studied using impedance spectroscopy, galvanostatic intermittent titration technique, cyclic voltammetry, electrochemical cycling, and differential scanning calorimetry (DSC). The electronic conductivity of partially charged material (a {le} 0.8) increases substantially when the cobalt content is increased to x = 0.3 from 0.2. The mobility, chemical diffusion coefficient, and Li{sup +} ion diffusion coefficient in the partially charged material are in the neighborhood of 10{sup {minus}6}cm{sup {minus}2}/V x, 10{sup {minus}8}cm{sup 2}/s, and 5 x 10{sup {minus}10}cm{sup 2}/s, respectively, and are rather insensitive to the values of a and x. Results of electrochemical and DSC studies show that LiNi{sub 0.7}Co{sub 0.3}O{sub 2} is the best cathode material for a Li cell of all materials studied here in view of the best cycle stability, the smallest irreversible capacity, and the greatest thermal stability with minimal reduction of specific capacity from that of LiNiO{sub 2}.
