Furthermore, they have the ability to learn information from a large volume of data. Unfortunately, not all of the sources available are secure and there is a possibility that an adversary in the environment has the malicious intention to poison a training dataset to cause the neural network to have a poor generalization error. Therefore, it is important to observe how susceptible a neural network is to the free parameters (i.e., gradient thresholds, hidden layer size, etc.) and the availability of adversarial data. In this work, we study the impact of an adversary for language models with Long Short-Term Memory (LSTM) networks and its configurations. We experimented with the Penn Tree Bank (PTB) dataset and adversarial text that was sampled from works in a different era. Our results show that there are several effective ways to poison such an LSTM language model. Furthermore, from our experiments, we are able to provide suggestions about the steps that can be taken to reduce the impact of such attacks.","PeriodicalId":235735,"journal":{"name":"2018 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121643591","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}

Electroencephalographic signals are acquired when a subject engages himself/herself in familiar or unfamiliar face recognition tasks. The signals are analyzed through source Iocalization using eLORETA and artifact removal by ICA from a set of channels corresponding to those selected sources, with an ultimate aim to classify the EEG responses of familiar and unfamiliar faces. The EEG responses of the two different classes (familiar and unfamiliar face recognition)are distinguished by analyzing the Event Related Potential signals that reveal the existence of large N250 and P600 signals during familiar face recognition.The paper introduces a novel LSTM classifier network which is designed to classify the ERP signals to fulfill the prime objective of this work. The first layer of the novel LSTM network evaluates the spatial and local temporal correlations between the obtained samples of local EEG time-windows. The second layer of this network models the temporal correlations between the time-windows. An attention mechanism has been introduced in each layer of the proposed model to compute the contribution of each EEG time-window in face recognition task. Performance analysis reveals that the proposed LSTM classifier with attention mechanism outperforms the efficiency of the conventional LSTM and other classifiers with a significantly large margin. Moreover, source Iocalization using eLORETA shows the involvement of inferior temporal and frontal lobes during familiar face recognition and pre-frontal lobe during unfamiliar face recognition. Thus, the present research outcome can be used in criminal investigation, where meticulous differentiation of familiar and unfamiliar face detection by criminals can be performed from their acquired brain responses.","PeriodicalId":235735,"journal":{"name":"2018 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121351865","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}

Vehicle platooning is one of the areas in road transportation that can be improved to reduce road freight operational costs. In this paper, an MPC (Model Predictive Control) algorithm is formulated based on the combination of Constant Distance (CD) and Headway Time (HT) topology. The simulations are carried out for platooning of Heavy Duty Vehicles (HDVs) using an integrated simulation platform, which combines VISSIM, MATLAB and Network Simulator (NS3). Deliberate communication failures are introduced through NS3 to study the platoon behavior. Further, a solution is proposed to avoid the channel crowding issue. Simulations of the platoon controller indicate that the vehicles follow a desired speed and maintain a desired intervehicular distance. It is also found that the platoon controller avoids collisions due to consecutive packet drops. Finally, an improvement in Packet Delivery Ratio (PDR) is observed with the proposed solution to avoid channel crowding issue.","PeriodicalId":235735,"journal":{"name":"2018 IEEE Symposium Series on Computational Intelligence (SSCI)","volume":"162 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127990402","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}

Increasing the integration of renewable energy sources, such as photovoltaic (PV) power has a significant impact on the power system operation and control. The variability and uncertainty of renewable energy poses the challenges of power and frequency fluctuations. Predictive analytics in power generation can provide a smarter grid with better control. Computational intelligence (CI) paradigms based on adaptive learning play a pivotal role in predictive analytics in smart grid.

The feasibility of our model is tested using a swarm consisting of real hardware robots, the so-called Kilobots.

We have considered two most common pre-training methods namely deep belief network and stacked autoencoder, and compared the results with the standard training algorithm without pretraining. The models with pretraining performed better than the model without pretraining in terms of error, convergence and the prediction of pattern. The results of the experiments also show the importance of hyperparameters tuning, specially learning rate, in providing a better prediction result.
