Industrial Automation using Robot Programming by Demonstration Technique with Neuroph Framework

PbD is a one way where the demonstrator is demonstrating the task to the arm with his / her own hands & gives directions to the arm. So, the same task is then learned by the system which is then replicated by the system itself. Learning by showing, PbD (Programming by Demonstration), shadowing are the other type of techniques. All of them are one and the same thing. But their use differs slightly in the many articles.

Robot programming by demonstration through system

Robot programming by demonstration through system identification

However, traditional robot programming techniques require specialised technical skills from different disciplines and it is not reasonable to expect end-users to have these skills. In this paper, we therefore present a new method of obtaining robot control code — programming by demonstration through system iden- tification — which algorithmically and automatically transfers human behaviours into robot control code, using transparent, analysable mathematical functions. Besides providing a simple means of generating perception-action mappings, they have the additional advantage that can also be used to form hypotheses and theoretical analysis of robot behaviour.

Coping with demonstration suboptimality in robot programming by demonstration

Coping with demonstration suboptimality in robot programming by demonstration

and Xu [140] use a neural net to capture human skill for controlling a light source. A mobile platform is moved randomly to produce a shadow from a human held light in a pre-specified target area. Human strategies for moving the light source to remove the shadow are used to train the net. Koeppe and Hirzinger [98] use a neural net to map task geometry to a control command for a compliant motion controller. They identify the lack of richness of geometric information in force and velocity signals used in other work. They propose instead, as input for their neural net, signals from visual and kinesthetic sensing modes. The approach was verified on a low-tolerance, peg-in-hole task. Kaiser and Dillman [63] also propose neural nets for PhD, however this work includes a phase of reinforced learning in the the PbD process. These authors initially use PbD to program the robot, but recognise that robot performance can be improved if it is allowed to learn and adapt according to its own experience. Experiments are presented for peg-in-hole and door-opening tasks. They show how initially poor robot performance at the first execution attem pt can be improved by repeated bouts of execution and learning. Other approaches that use neural nets in PbD can also be found in [115, 88, 137, 135, 99]. While the neural net approach has met with some success, there have been problems with training neural nets directly from demonstration because of inconsistent motion typically generated by human demonstrators. Essentially the issue is one of the neural net approximating a skill function that includes noise in the demonstration.

MAXIMIZED RESULT RATE JOIN ALGORITHM

MAXIMIZED RESULT RATE JOIN ALGORITHM

The objective of this work is to outline a comprehensive review and synthesis of the current state-of-the-art related to EUP for the web mashups. 204 articles were identified based on the search keywords, of which 21 were found to be relevant. The articles were divided into two main groups; research articles and survey articles. Six EUP approaches for web mashups were identified from the studies; browsing, programming-by-demonstration (PBD), spreadsheet, widget paradigm, data-flow and block-based approach. Other researches regarding EUP for web mashups were identified, such as ubiquitous platform mashups, users’ support functions, data extraction techniques and process-oriented mashups. The findings show that there are still many areas that need to be explored such as ubiquitous platform mashups, lightweight frameworks, enterprise mashups etc. The developments of mashup tools that are supposed to assist end-users in making mashups still have limitations. While most mashup tools have been developed to have a simple user interface, to be easy to use and learn, to be reusable and extendable and to be able to be customized, and yet other outstanding criteria in mashup tools are flexibility and adaptability.

Abstract: Command-line interfaces are heavily used by system administrators to manage computer systems. Tasks performed at a command line may often be repetitive, leading to a desire for automation. However, the critical nature of system administration suggests that humans also need to supervise an automated system’s behavior. This paper presents a programming by demonstration approach to capturing repetitive command line procedures, which is based on a machine learning technique called version space algebra. The interactive design of this learning system enables the user to supervise the system’s training process, as well as allowing the user and system to alternate control of the learned procedure’s execution.

New Dimensions in Testimony Demonstration

New Dimensions in Testimony Demonstration

New Dimensions in Testimony is a prototype dialogue system that allows users to conduct a conversation with a real person who is not available for conversation in real time. Users talk to a persistent representation of Holocaust survivor Pinchas Gutter on a screen, while a dialogue agent selects appropriate responses to user utterances from a set of pre-recorded video statements, simulating a live conversa- tion. The technology is similar to existing conversational agents, but to our knowledge this is the first system to portray a real per- son. The demonstration will show the system on a range of screens (from mobile phones to large TVs), and allow users to have individual conversations with Mr. Gutter.

Adoption of Pair Programming in the Academic Environment with Different Degree of Complexity in Students Perspective– An Empirical Study

Adoption of Pair Programming in the Academic Environment with Different Degree of Complexity in Students Perspective– An Empirical Study

The Pair Programming based on the driver-navigator model has been successful in the learning environment. Its success is noticeable in better performance in computer science programming and non programming mathematical assignments, increased team work in and outside class, enhanced learning, and decreased frustration We have conducted three experiments with students in both programming and non programming course. The data collected from the experiments have been used to analyze about the efficiency of pair programming. The results showed that there is significant increase in the knowledge when using pair programming both in the programming course and non programming course. Furthermore, unlike previous experiments, the effect of PP was investigated in the context of performance and knowledge transfer. If each person in the team paired with only one other person on the team, many benefits would be realized – quality gains, communication gains, teamwork gains, trust building, etc. However, even more can be gained by dynamically assigning the partners based on the task at hand. Two of these additional gains relate to knowledge management and to training. Pairing is an excellent knowledge management strategy because it breaks down communication barriers between teammates. They get to know each other and each seems more approachable when a question arises. Also, by pairing with many different people, developers learn more about many aspects of the system and more about the programming and tool techniques of many different people. Pair rotation also reduces the training time to assimilate a new team member and distributes the burden of training throughout the team. We are also developing software tools that will aid in the analysis of the experimental sessions. This logging can be used to generate automatically a set of measures for comparing development styles, and serves as an analysis baseline that can be extended by hand-coding. Our research on pair programming will continue by performing case studies at companies using pair programming. In Industries it is very challenging to arrange even quasi-experiments, but on the other hand case studies can give valuable qualitative information on how pair programming should be practiced in industry.

acquisition card leading to the NI ELVIS system. A background debug (BDM) pod 4 is connected from the host PC to a BDM connector on the microcontroller (MCU) module. CodeWarrior ® development software supports debugging through a BDM pod connected to a printer port or USB port on the PC, or a serial I/O connection from a PC serial port to a serial interface on the MCU module may be used in place of the BDM pod (see serial monitor discussion later in this paper). The NI ELVIS block includes power supplies, digital I/O, and indicator LEDs, as well as a large breadboard area for the MCU module and experiment circuitry. The MCU block includes an MC9S12C32 16-bit MCU along with a crystal, RS-232 level shifters, and a BDM connector for programming and debugging the application software. The dc motor interface block includes the motor, a 2-transistor circuit to translate the 0-5v PWM signal from the MCU into a 0-15v signal to drive the motor. Though not used in this demonstration lab, the dc motor interface block also includes an optical interrupter sensor that can be used to monitor motor speed using a slotted disk attached to the motor shaft.

A Decision Aid Approach for Optimisation Problems Involving Several Economic Functions

A Decision Aid Approach for Optimisation Problems Involving Several Economic Functions

Many concrete real life problems ranging from economic and business to industrial and engineering may be cast into a multi-objective optimisation framework. The redundancy of existing methods for solving this kind of problems suscep- tible to inconsistencies, coupled with the necessity for checking inherent assumptions before using a given method, make it hard for a nonspecialist to choose a method that fits well the situation at hand. Moreover, using blindly a me- thod as proponents of the hammer principle (when you only have a hammer, you want everything in your hand to be a nail) is an awkward approach at best and a caricatural one at worst. This brings challenges to the design of a tool able to help a Decision Maker faced with these kinds of problems. The help should be at two levels. First the tool should be able to choose an appropriate multi-objective programming technique and second it should single out a satisfying solu- tion using the chosen technique. The choice of a method should be made according to the structure of the problem and to the Decision Maker’s judgment value. This paper is an attempt to satisfy that need. We present a Decision Aid Ap- proach that embeds a sample of good multi-objective programming techniques. The system is able to assist the Decision Maker in the above mentioned two tasks.

MRMR BA: A HYBRID GENE SELECTION ALGORITHM FOR CANCER CLASSIFICATION

This study also assessed the usability and effectiveness of using pair programming from different perspectives and criteria, such as gender, course, specialization, and student level. The results show that females exhibit better mean values than males. In addition, Applied Physics and Geological Engineering have mean values greater than 4. All other specializations present a good mean; among which, the smallest value is 3.10, as shown in Table 5. Moreover, by comparing the results of the questionnaire according to student level, the researchers found that students at the fourth year level were more willing to use pair programming than that those in other levels. Furthermore, the mean values for all the involved students in all the courses were convergent, as shown in Table 6.

Relevance of Object-Oriented Programming in Computer Education

Relevance of Object-Oriented Programming in Computer Education

On the other hand, structured programming refers to the technique that produces programs with clean flow, clear design, and a degree of modularity or hierarchical structure. It has prominent benefits such as ease of maintenance and ease of readability by other programmers. Though, structured programming remains an enormously successful approach for dealing with complex problems, by the late 1980s, some of the deficiencies of structured programming had become too glaring. Firstly, it is natural to think of your data and what you can do with your data as related ideas. Secondly, programmers found themselves constantly reinventing new solutions to old problems. This is called “re-inventing the wheel” which is the opposite of re-usability. Obviously, Object Oriented Programming is a programming paradigm based on the concept of “objects” which are data in the form of fields, often known as attributes and code in the form of procedures often known as methods, attributes and code. A distinguishing feature of objects is that an object procedure can access and often modify the data fields of the objects with which they are associated. According to

The hazards of perception : evaluating a change blindness demonstration within a real world driver education course

The hazards of perception : evaluating a change blindness demonstration within a real world driver education course

The main aim of the current study was to develop and assess the feasibility and effectiveness of presenting a change blindness demonstration within a driver edu- cation course. We predicted that demonstrating to participants that their visual system is not infallible might reduce unfounded confidence in their observa- tional abilities. A necessary first step for our analysis was establishing whether one of the key learning points from the change blindness intervention had been achieved. This was whether participants had been made aware of how difficult it can be to detect important changes in our immediate environment. Our results suggest that this message was delivered successfully. Participants, on average, stated that it was more difficult to “spot impor- tant visual information” after they had viewed the demonstrations. This occurred when the questionnaires were administered in a within-participants design (Experi- ments 1 and 2) and in a between-participants design (Experiment 2), in which there was no opportunity for a pre-test/post-test response bias to occur. Furthermore, this change was observed only following the change blind- ness intervention and not after the other “pseudo-inter- ventions ” (visual search or difficult questions).
