{"title":"Neural Network Learning of Context-Dependent Affordances","authors":"Luca Simione, A. Borghi, S. Nolfi","doi":"10.33969/ais.2022040106","DOIUrl":"https://doi.org/10.33969/ais.2022040106","url":null,"abstract":"In this paper, we investigated whether affordances are activated automatically, independently of the context in which they are experienced, or not. The first hypothesis postulates that stimuli affording different actions in different contexts tend to activate all actions initially. The action appropriate to the current context is later selected through a competitive process. The second hypothesis instead postulates that only the action appropriate to the current context is activated. The apparent tension between these two alternative hypotheses constitutes an open issue since, in some cases, experimental evidence supports the context-independent hypothesis, while in other cases it supports the context-dependent hypothesis. To study this issue, we trained a deep neural network with stimuli in which action inputs co-varied systematically with visual inputs. The neural network included two separate pathways for encoding visual and action inputs with two hidden layers each, and then a common hidden layer. The training was realized through an auto-associative unsupervised learning algorithm and the testing was conducted by presenting only part of the stimulus to the neural network, to study its generative properties. As a result of the training process, the network formed visual-action affordances. Furthermore, we conducted the training process in different contexts in which the relation between stimuli and actions varied. The analysis of the obtained results indicates that the network displays both a context-dependent activation of affordances (i.e., the action appropriate to the current context tends to be more activated than the alternative action) and a competitive process that refines action selection (i.e., that increases the offset between the activation of the appropriate and unappropriate actions). Overall, this suggests that the apparent contradiction between the two hypotheses can be resolved. Moreover, our analysis indicates that the greater facility with which colour-action associations are acquired with respect to shape-action associations is because the representation of surface features, such as colour, tends to be more readily available for deeper features, such as shape. Our results support the feasibility of human-like affordance acquisition in artificial neural networks trained using a deep learning algorithm. This model could be further applied to a number of robotic and applicative scenarios.","PeriodicalId":273028,"journal":{"name":"Journal of Artificial Intelligence and Systems","volume":"22 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":"134062067","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 center is none other than the center of the last closed Anticyclone's isobar. The monthly climatological mean value of the center coordinates are the data to be modeled by fuzzy inference system. The considered model parameters are the partitions number of the discourse universe and the model order. After evaluating the deviation between the input data and the simulated data, the minimum deviation is obtained with order model 2 by using 50 numbers of partitions.","PeriodicalId":273028,"journal":{"name":"Journal of Artificial Intelligence and Systems","volume":"59 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":"116129053","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}

Chiroma","doi":"10.33969/ais.2021.31010","DOIUrl":"https://doi.org/10.33969/ais.2021.31010","url":null,"abstract":"Deep Learning algorithms (DL) have been applied in different domains such as computer vision, image detection, robotics and speech processing, in most cases, DL demonstrated better performance than the conventional machine learning algorithms (shallow algorithms). The artificial intelligence research community has leveraged the robustness of the DL because of their ability to process large data size and handle variations in biometric data such as aging or expression problem. Particularly, DL research in automatic fingerprint recognition system (AFRS) is gaining momentum starting from the last decade in the area of fingerprint pre-processing, fingerprints quality enhancement, fingerprint feature extraction, security of fingerprint and performance improvement of AFRS. However, there are limited studies that address the application of DL to model fingerprint biometric for different tasks in the fingerprint recognition process. To bridge this gap, this paper presents a systematic literature review and an insightful meta-data analysis of a decade applications of DL in AFRS. Discussion on proposed model’s tasks, state of the art study, dataset, and training architecture are presented. The Convolutional Neural Networks models were the most saturated models in developing fingerprint biometrics authentication. The study revealed different roles of the DL in training architecture of the models: feature extractor, classifier and end-to-end learning. The review highlights open research challenges and present new perspective for solving the challenges in the future. The author believed that this paper will guide researchers in propose novel fingerprint authentication scheme.","PeriodicalId":273028,"journal":{"name":"Journal of Artificial Intelligence and Systems","volume":"71 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":"127171287","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}

In the present model, we analyze the system under the consideration of two warehouses and without shortages with the assumptions of the linear demand function (increasing function of time). Generally, in today’s business scenario for sessional products, some constraints like storage cost, deteriorating cost, and ordering cost change with their original values. Therefore, these constraints cannot be assumed to be constant in that situation. Depending on these facts that we handle these costs as a triangular fuzzy number and hence apply the signed distance technique to solve the corresponding problem. The key objective of this work is to determine the optimal inventory level, and inventory time schedule to a minimum of the whole inventory cost. The proposed model is demonstrated with two numerical examples to observe the behavior of constraints with system cost and compare their performance with and without fuzzy environment.","PeriodicalId":273028,"journal":{"name":"Journal of Artificial Intelligence and Systems","volume":"16 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":"129434708","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}
