Connectionist inductive inference typically involves gradient descent algorithms in weight space. When inferring functions of unbounded sequences such algorithms run on recurrent nets and become computationally expensive. A broader framework for inductive inference is presented, and it is shown that such problems admit a dual approach, which can be phrased in terms of the simulation-as-homomorphism perspective in systems theory. Whereas the usual approach adapts the dynamics of the net to match the dynamics of the target system, the dual approach keeps the dynamics fixed and learns a homomorphism from the net to the target. The latter technique is promising because of its efficiency and its direct applicability to learning by continuous nonconnectionist system, such as neural fields.<<ETX>>","PeriodicalId":250037,"journal":{"name":"IEEE 1991 International Conference on Systems Engineering","volume":"5 1‐2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133111063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This type of reinforcement signals only that the generated policy is correct, or incorrect, and provides no information on the closeness of the generated policy to the correct policy. SAELS uses the drive-reinforcement neuronal model that, through the predictive qualities of its learning, is capable of solving the temporal credit assignment problem that arises under these reinforcement conditions. It is shown that SAELS can generate the necessary decision policy to maneuver through a multi-intersection maze.<<ETX>>","PeriodicalId":250037,"journal":{"name":"IEEE 1991 International Conference on Systems Engineering","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130646317","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To establish a framework for comparison, the example of a shunt DC motor is studied. It was found that the conditions for applying the method of feedback linearization were not satisfied; the full 3D state-space system could not be linearized by state transformation. It was found that, after eliminating a state and therefore reducing the dimension from three to two, the system became feedback linearizable. In other words, the dynamics associated with the remaining two states could be linearized by change of coordinates and state feedback. A similar situation occurred with the input/output linearization, except that the dynamics that were linearized were those associated with the rotor position and velocity, while the remaining dynamics (associated with the field current) were made unobservable.<<ETX>>","PeriodicalId":250037,"journal":{"name":"IEEE 1991 International Conference on Systems Engineering","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115761103","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Image data are gathered and processed by the combination of image processing hardware and a CCD camera. A UNIX workstation is designated to provide intelligence to the system by understanding the environment of the robot through image data. It also provides online data analysis capability. The system was checked by an object following experiment where the robot chases a pair of alternatively lit LEDs. Data acquisition and analysis capability was built into the system. A mathematical model of the manipulator was obtained. The model was used in designing a digital compensator. The compensator was implemented in the form of a software servo and successfully suppressed oscillatory response of the manipulator.<<ETX>>","PeriodicalId":250037,"journal":{"name":"IEEE 1991 International Conference on Systems Engineering","volume":"61 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128154304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
