A Modular Software Architecture for Heterogeneous Robot Tasks

AAAI Conferences

Swarthmore's entries to this year's AAAI Mobile Robot competition won second place in the Urban Search and Rescue event and Third Place in the Robot Host competition. This article describes the features of Frodo and Rose, the two-robot team, and discusses their performance.

A Faster Algorithm for Learning Decision Trees With Module Nodes

AAAI Conferences

One of the challenging problems regarding learning decision trees is whether decision trees over the domain Z, in which each internal node is labeled by a module function axi(mod N) for some i E (1....,n), are efficiently learnable with equivalence and membership queries [5]. Given any decision tree T, let s be the number of its leaf nodes. Let N p l...p be its prime decomposition, and let 7(N) (tl 1)... (t 1). We show that when all the module functions in T have the same coefficient, then there is a polynomial time algorithm for learning T using at most s(s 1)7(N) equivalence queries and at most s2nT(N) membership queries. Our algorithm is substantially more efficient than the algorithm designed in [7] for learning such decision trees. When N is a prime, our algorithm implies the best-known algorithm in [4] for learning decision trees over a finite alphabet.

LG G5 Hi-Fi Plus audio module skips over the U.S. market


Bad news if you were looking forward to some killer audio with your new LG G5. It looks like the B&O Hi-Fi Plus module won't be on sale in the U.S. anytime soon. As first spotted by Android Authority, the item has been removed from the U.S. page for LG Friends, which lists all the modules that can pair up with the new G5. Yet on the UK site, the module is there and ready for purchase. LG offered a brief statement, declaring that, "At this time, we don't have an availability date set for the Hi-Fi DAC, and so don't have timing to share.

Cloud-Compatible Wi-Fi Module Simplifies and Secures IoT and M2M Applications


April 21, 2017 – The latest Cloud-compatible Wi-Fi module from STMicroelectronics is set to accelerate development of all kinds of IoT and M2M devices. The new module provides advanced Internet-security and application protocols, and features a microcontroller capable of supporting operation in standalone or serial-to-Wi-Fi modes. Further extra features include a hardware cryptographic accelerator and an SPI port for faster host communications. In addition, the new MicroPython scripting engine dramatically simplifies development of custom applications to run directly on the module in standalone mode. Host interactions can use AT commands via a UART, compatible with the previous generation of Wi-Fi modules, or equivalent proprietary protocol over SPI.
