From the buzzing in Turing’s head to machine intelligence contests
This paper presents an analysis of three major contests for machine intelligence. We conclude that a new era for Turing’s test requires a fillip in the guise of a committed
sponsor, not unlike DARPA, funders of the successful 2007

VideoCapsuleNet: A Simplified Network for Action Detection
The recent advances in Deep Convolutional Neural Networks (DCNNs) have shown
extremely good results for video human action classification, however, action
detection is still a challenging problem. The current action detection
approaches follow a complex pipeline which involves multiple tasks such as tube
proposals, optical flow, and tube classification. In this work, we present a
more elegant solution for action detection based on the recently developed
capsule network. We propose a 3D capsule network for videos, called
VideoCapsuleNet: a unified network for action detection which can jointly
perform pixel-wise action segmentation along with action classification. The
proposed network is a generalization of capsule network from 2D to 3D, which
takes a sequence of video frames as input. The 3D generalization drastically
increases the number of capsules in the network, making capsule routing
computationally expensive. We introduce capsule-pooling in the convolutional
capsule layer to address this issue which makes the voting algorithm tractable.
The routing-by-agreement in the network inherently models the action
representations and various action characteristics are captured by the
predicted capsules. This inspired us to utilize the capsules for action
localization and the class-specific capsules predicted by the network are used
to determine a pixel-wise localization of actions. The localization is further
improved by parameterized skip connections with the convolutional capsule
layers and the network is trained end-to-end with a classification as well as
localization loss. The proposed network achieves sate-of-the-art performance on
multiple action detection datasets including UCF-Sports, J-HMDB, and UCF-101
(24 classes) with an impressive ~20% improvement on UCF-101 and ~15%
improvement on J-HMDB in terms of v-mAP scores
Recreation of the 28-entity IGES test file using the ComputerVision CADDS 4X
An Initial Graphics Exchange Specification (IGES) test file is called the 28 Entity IGES Test File. This file contains 28 geometric and annotation entities which are considered the basic entities that an IGES translator for any CAD system should support. The main purpose was to determine how the IGES preprocessor supports the 28 entities through recreation of the 28 Entity IGES Test File on the ComputerVision CADDS 4X. Test procedure is described and test results are presented
Fertility Response to the Tax Treatment of Children
One of the most commonly cited studies on the effect of child subsidies on fertility, Whittington, Alm, and Peters (1990), claimed a large positive effect of child tax benefits on fertility using time series methods. We revisit this question in light of recent increases in child tax benefits by replicating this earlier study and extending the analysis with an additional 20 years of data. We find that their results suffer from the spurious regression problem, and are not robust to differencing. We find evidence of a statistically significant fertility response to a change in the real value of child tax subsidies occurring with a one- to two-year lag, but a much smaller and statistically insignificant total effect after several years, suggesting that a change in the child tax subsidy most strongly affects the timing of births.fertility, income taxation, child tax benefits, personal exemption
The 28-entity IGES test file results using ComputerVision CADDS 4X
The investigation was based on the following steps: (1) Read the 28 Entity IGES (Initial Graphics Exchange Specification) Test File into the CAD data base with the IGES post-processor; (2) Make the modifications to the displayed geometries, which should produce the normalized front view and the drawing entity defined display; (3) Produce the drawing entity defined display of the file as it appears in the CAD system after modification to the geometry; (4) Translate the file back to IGES format using IGES pre-processor; (5) Read the IGES file produced by the pre-processor back into the CAD data base; (6) Produce another drawing entity defined display of the CAD display; and (7) Compare the plots resulting from steps 3 and 6 - they should be identical to each other
Design of equipment for lunar dust removal
NASA has a long range goal of constructing a fully equipped, manned lunar base on the near side of the moon by the year 2015. During the Apollo Missions, lunar dust coated and fouled equipment surfaces and mechanisms exposed to the lunar environment. In addition, the atmosphere and internal surfaces of the lunar excursion module were contaminated by lunar dust which was brought in on articles passed through the airlock. Consequently, the need exists for device or appliance to remove lunar dust from surfaces of material objects used outside of the proposed lunar habitat. Additionally, several concepts were investigated for preventing the accumulation of lunar dust on mechanisms and finished surfaces. The character of the dust and the lunar environment present unique challenges for the removal of contamination from exposed surfaces. In addition to a study of lunar dust adhesion properties, the project examines the use of various energy domains for removing the dust from exposed surfaces. Also, prevention alternatives are examined for systems exposed to lunar dust. A concept utilizing a pressurized gas is presented for dust removal outside of an atmospherically controlled environment. The concept consists of a small astronaut/robotic compatible device which removes dust from contaminated surfaces by a small burst of gas
