EMBEDDED LEARNING ROBOT WITH FUZZY Q-LEARNING FOR OBSTACLE AVOIDANCE BEHAVIOR
Fuzzy Q-learning is extending of Q-learning algorithm that uses fuzzy inference system to enable Q-learning holding continuous action and state. This learning has been implemented in various robot learning application like obstacle avoidance and target searching. However, most of them have not been realized in embedded robot. This paper presents implementation of fuzzy Q-learning for obstacle avoidance navigation in embedded mobile robot. The experimental result demonstrates that fuzzy Q-learning enables robot to be able to learn the right policy i.e. to avoid obstacle
Throughput Scaling Of Convolution For Error-Tolerant Multimedia Applications
Convolution and cross-correlation are the basis of filtering and pattern or
template matching in multimedia signal processing. We propose two throughput
scaling options for any one-dimensional convolution kernel in programmable
processors by adjusting the imprecision (distortion) of computation. Our
approach is based on scalar quantization, followed by two forms of tight
packing in floating-point (one of which is proposed in this paper) that allow
for concurrent calculation of multiple results. We illustrate how our approach
can operate as an optional pre- and post-processing layer for off-the-shelf
optimized convolution routines. This is useful for multimedia applications that
are tolerant to processing imprecision and for cases where the input signals
are inherently noisy (error tolerant multimedia applications). Indicative
experimental results with a digital music matching system and an MPEG-7 audio
descriptor system demonstrate that the proposed approach offers up to 175%
increase in processing throughput against optimized (full-precision)
convolution with virtually no effect in the accuracy of the results. Based on
marginal statistics of the input data, it is also shown how the throughput and
distortion can be adjusted per input block of samples under constraints on the
signal-to-noise ratio against the full-precision convolution.Comment: IEEE Trans. on Multimedia, 201
Reliable Linear, Sesquilinear and Bijective Operations On Integer Data Streams Via Numerical Entanglement
A new technique is proposed for fault-tolerant linear, sesquilinear and
bijective (LSB) operations on integer data streams (), such as:
scaling, additions/subtractions, inner or outer vector products, permutations
and convolutions. In the proposed method, the input integer data streams
are linearly superimposed to form numerically-entangled integer data
streams that are stored in-place of the original inputs. A series of LSB
operations can then be performed directly using these entangled data streams.
The results are extracted from the entangled output streams by additions
and arithmetic shifts. Any soft errors affecting any single disentangled output
stream are guaranteed to be detectable via a specific post-computation
reliability check. In addition, when utilizing a separate processor core for
each of the streams, the proposed approach can recover all outputs after
any single fail-stop failure. Importantly, unlike algorithm-based fault
tolerance (ABFT) methods, the number of operations required for the
entanglement, extraction and validation of the results is linearly related to
the number of the inputs and does not depend on the complexity of the performed
LSB operations. We have validated our proposal in an Intel processor (Haswell
architecture with AVX2 support) via fast Fourier transforms, circular
convolutions, and matrix multiplication operations. Our analysis and
experiments reveal that the proposed approach incurs between to
reduction in processing throughput for a wide variety of LSB operations. This
overhead is 5 to 1000 times smaller than that of the equivalent ABFT method
that uses a checksum stream. Thus, our proposal can be used in fault-generating
processor hardware or safety-critical applications, where high reliability is
required without the cost of ABFT or modular redundancy.Comment: to appear in IEEE Trans. on Signal Processing, 201
Failure Mitigation in Linear, Sesquilinear and Bijective Operations On Integer Data Streams Via Numerical Entanglement
A new roll-forward technique is proposed that recovers from any single
fail-stop failure in integer data streams () when undergoing
linear, sesquilinear or bijective (LSB) operations, such as: scaling,
additions/subtractions, inner or outer vector products and permutations. In the
proposed approach, the input integer data streams are linearly superimposed
to form numerically entangled integer data streams that are stored in-place
of the original inputs. A series of LSB operations can then be performed
directly using these entangled data streams. The output results can be
extracted from any entangled output streams by additions and arithmetic
shifts, thereby guaranteeing robustness to a fail-stop failure in any single
stream computation. Importantly, unlike other methods, the number of operations
required for the entanglement, extraction and recovery of the results is
linearly related to the number of the inputs and does not depend on the
complexity of the performed LSB operations. We have validated our proposal in
an Intel processor (Haswell architecture with AVX2 support) via convolution
operations. Our analysis and experiments reveal that the proposed approach
incurs only to reduction in processing throughput in comparison
to the failure-intolerant approach. This overhead is 9 to 14 times smaller than
that of the equivalent checksum-based method. Thus, our proposal can be used in
distributed systems and unreliable processor hardware, or safety-critical
applications, where robustness against fail-stop failures becomes a necessity.Comment: Proc. 21st IEEE International On-Line Testing Symposium (IOLTS 2015),

Cultural Symbiosis in Society Relationship: Philosophy and Psychological Perspectives
In this article I want to share the idea of relationship symbiosis and its effects on the future of marriage and breakdowns in couples. Symbiosis is the connection two people find between them at the beginning of relationships that cause initial attraction and the decision making process to marry or cohabitate. Culture plays a significant role in symbiosis along with development issues from the type of parental style experienced in early childhood
Robust Modeling of Epistemic Mental States
This work identifies and advances some research challenges in the analysis of
facial features and their temporal dynamics with epistemic mental states in
dyadic conversations. Epistemic states are: Agreement, Concentration,
Thoughtful, Certain, and Interest. In this paper, we perform a number of
statistical analyses and simulations to identify the relationship between
facial features and epistemic states. Non-linear relations are found to be more
prevalent, while temporal features derived from original facial features have
demonstrated a strong correlation with intensity changes. Then, we propose a
novel prediction framework that takes facial features and their nonlinear
relation scores as input and predict different epistemic states in videos. The
prediction of epistemic states is boosted when the classification of emotion
changing regions such as rising, falling, or steady-state are incorporated with
the temporal features. The proposed predictive models can predict the epistemic
states with significantly improved accuracy: correlation coefficient (CoERR)
for Agreement is 0.827, for Concentration 0.901, for Thoughtful 0.794, for
Certain 0.854, and for Interest 0.913.Comment: Accepted for Publication in Multimedia Tools and Application, Special

Price Discrimination and Social Welfare with Demand Uncertainty
Price, output and welfare erects of third-degree price discrimination is analyzed in the context of a risk-averse monopolist, who commits to xed prices before the revelation of random and potentially correlated demands. Assuming the disturbance term to be additive, white noise and the monopolist to have a quadratic (mean-variance) utility function, we show that price discrimination may occur with identical expected demands, the relatively risky but price insensitive market may be charged the lower price and despite linear demands, aggregate expected output may fall while social welfare rises. All of these results, which run counter to those in the deterministic model, are shown to be driven by the asymmetry in the revenue and risk characteristics of the markets and the willingness of the monopolist to trade increased level for reduced risk of expected prot in a manner similar to portfolio choice with risky and correlated assets.

Teachersâ Perception about Authentic Materials and Their Implementation in the Classroom
Authentic materials are one of common materials in teaching English. Most of teacher usually use them to be implemented into their classroom. One of the reasons of the teachers they use it in the classroom is in order to give the students example of the real use of English in social life. Other than authentic materials, the teachers also usually use textbook. It is because textbook gives much easier for the teachers to use it in the classroom and also for the students to studied at home. In implementing the authentic materials is not as easy as using textbook. The teachers need to be creative to select and modify the authentic materials to be able to be implemented. It is because the authentic materials are not produced for pedagogical purposes. So, in this study, the objectives of the researcher are to seek about the perception of using authentic materials in the classroom, the reasons of the teachers about the perception, and also the way of the teachers when implementing the authentic materials in the classroom. Regarding the objectives above, the qualitative research is appropriate to be conducted in this study. It is in order to get the deep data from the research subject. To get the data, this study uses interview and observation. By the interview, it gets the answer of all the research questions. And by the observation, it gets the supporting data from the interview. For data analysis, this study uses Dornyei theory to analyze the data. It is started from transcribing the data, coding, growing ideas, interpreting the data, and drawing conclusion. The result of the research found that most of the teachers give positive response about using authentic materials in their teaching. They perceive that authentic materials are very important to be implemented in the classroom. The teachers also enjoy during the implementation of the authentic materials. They also perceive that authentic materials are very easy to get. And, the last perception is some of the authentic materials are very difficult for the students. For the conclusions, most of teachers are agree about the use of authentic materials for teaching English. Beyond the importance of the authentic materials the teachers only use several authentic materials that provide entertaining to the students like song and movies. The teachers rarely used kinds of authentic materials that contains text like newspaper, magazine and article in order to the difficulties of the words used in the text. Most of the teachers use kinds of authentic materials just to be supplementary materials other than using textbook materials.
