Harmful documents make readers unpleasant on the Web. In order to hide the harmful documents from the public, machine learning methods have been proposed, which learn words used in harmful documents and hide them automatically. the learned words often have bad meanings. though word meanings are not changed, word impression may be changed on context. Even if a word with bad impression is contained in a document, the previous learning methods can not learn the word, and fail to hide documents. We select the following approach: word impression may be changed on context. If a word has been used with other words of good meaning, it is considered that impression of the word is also good. In contrast, if a word has been used with others of bad meaning, impression of the word may be bad. this paper proposes a new extraction method of harmful comments in a thread of a Bulletin Board System. the proposed method extracts comments using word meanings and word impression on thread context. We evaluated the proposed method using comments collected from four threads in Japanese BBS "2-channel." the averaged precision of extraction was 0.47, and the averaged recall was 0.68. We verified that the proposed method was suitable for extraction of harmful comments from a thread of a BBS.

In dealing with the large discrete action spaces, a joint action representation and prioritized experience replay method is proposed in this paper, which consists of three modules. In the first module, we use the k-nearest neighbor method to reduce the dimensionality of the original action space, generating a compact action space, and then the critic network is introduced to further evaluate and filter this compact space to obtain the optimal action. Note that the optimal action may have inconsistency with the actual desired action. then in the second module, we introduce a multi-step update technique to reduce the training variance when storing data in the replay buffer. In the third module, considering the existence of correlation between samples when sampling data, we assign the corresponding weight to the sample experience by calculating the absolute value of temporal difference error and use such a non-uniform sampling method to prioritize the samples for sampling. Experimental results on four benchmark environments demonstrate the effectiveness and efficiency of the proposed method in dealing with the large discrete action spaces. © 2023 ACM.

Aiming at the problems that the current decision-making model of ship collision avoidance does not consider international Regulations for Preventing Collisions at Sea (COLREGS), ship maneuverability, and the need for a lot of training time, combined with the advantages of reinforcement learning and imitation learning, a ship intelligent collision avoidance decision-making model based on Generic Adversary Imitation learning (GAIL) is proposed: Firstly, the collision avoidance data in Automatic Information System (AIS) data is extracted as expert data;Secondly, in the generator part, the environment model is established based on Mathematical Model Group (MMG) and S-57 chart rendering, and the state space, behaviour space and reward function of reinforcement learning are constructed. the deep deterministic policy gradient (DDPG) is used to interact with the environment model to generate ship trajectory data. At the same time, the generator can constantly learn expert data;Finally, a discriminator can distinguish the expert data from the data generated by the generator is constructed and trained. the model training is completed when the discriminator cannot distinguish the two. In order to verify the performance of the model, AIS data near the South China Sea is used to process and extract collision avoidance decision data, and a ship intelligent collision avoidance decision model based on GAIL is established. After the model converges, the final generated data is compared with the expert data. the experimental results verify that the model proposed in this paper can reproduce the expert collision avoidance trajectory and is a practical decision model of ship collision avoidance. © 2023 ACM.

Recently, ubiquitous computing and related sensor technology have significantly progressed. On the other side, the relationship between human emotion and sensory stimuli has been investigated. With this background, we propose sensory stimuli control system to adjust group emotion to given target emotion. Valence-arousal model was adapted for defining group emotion, and survey of 73-papers and onsite-investigation had done for domain knowledge. the proposed system is based on the partially observable Markov decision process to deal with the uncertain states of group emotion, and reinforcement learning approach to learn the criterion of decision in real time. To evaluate the proposed system, we collected 160-minutes data from kindergarten where the music and math classes are ongoing with 10 prescholers and 1 caregiver are participating. Our system produced 55.17% of accuracy, which outperfomed the original system by 15.51%p.

Nowadays cloud computing services have become the most popular internet-based computing and many organizations use their services. Due to this, many cyberattacks are happening in the cloud. One of those attacks is the Distributed-Denial-Of-Service (DDoS) attack. It floods unreal traffic, hence troubles the availability of the resources. this article is about DDoS attacks and detection of DDoS attacks using machine learning. there are many famous machine learning algorithms such as naïve bayes, random forest, support vector machines etc. these machine learning algorithms can be used to detect the DDoS attacks on cloud. there are several datasets available for the researchers to test their proposed models which include NSL-KDD, ICDX, CIDDS-001, CICIDS 2017 etc. this paper presents a detailed study on different machine learning based techniques proposed by various authors to detect the DDoS attack in the cloud environment. A brief explanation has been provided on the available datasets and further discussed about the general methodology. © 2023 IEEE.

Over the last decades, terroristic attacks have caused human tragedies and loss of human life and materials and had negative impact on the economy and the development of the world. there have been over 48,000 terrorist incidents from 2000 to 2014 claiming over 107,000 lives according to the Global Terrorism Index Gil. therefore, there is an urgent need for a system to proactively detect and predict any potential threats that can be caused by terrorist attacks. Artificial Intelligence (AI), Internet of things (IoT), and cloud technology can be integrated to prevent terroristic attacks. In this paper, I propose a novel framework called "We See You" (WSY). WSY is a complete comprehensive system framework which proposed to prevent and reduce the terroristic attacks by predicting any instance of terrorist attack. the prediction is based on monitoring the ongoing psychological and social behaviors, some important physiological signs and other markers, using IoT devices. Physiological signs related to the terrorist attacks include the blood concentration in the face, the eyes spotting, the gait, the hair and hair shaving, the face expressions, and the weight. the other personal markers include the clothes, the speech, the speech stress & emotion, and the smell. the prediction is based on the analysis of previous individual terrorist's profile (built from News, law enforcement records, etc.), and previous recording cases of video and audio of terrorist incidents. To the best of my knowledge, this framework system is the first framework that proposed to predict and identify the terrorist timely before the implementation of the suicide incidents, through the psychological and social behaviors, speech, some important physiological signs and other markers.

Food quality analysis can be carried out by spectral data acquired from spectrometers with its advantage of non-destructive way of testing. Portable and miniature spectroscopy can be a suitable solution when it meets the specifications such as portability, cost, and short processing time requirements, to enable ordinary citizens to use such a device in the fight against food fraud. Compared to more expensive, bulky, and non-portable devices, the data collected using miniature and portable spectrometers is of a lower quality and thus adversely affect the quality of the analysis. Research have been carried out to use machine learning (ML) classifiers on spectral data analysis for food quality assessment. the present work focuses on two aspects: firstly, preliminary exploratory statistical analysis is conducted on the real spectral data on different food products including oils, fruits and spices acquired from such miniature devices, which aims to evaluate and illustrate the distinctive characteristics of such spectral data, data distribution and difference in the spectra across multiple data acquisitions etc. along with a summary of the key challenges to face and explore. Secondly, a case study for the differentiation of extra virgin olive from adulterated with vegetable oil is provided to analyze and evaluate how some commonly used ML classifiers can be used for classification, while the impact of different preprocessing methods to improve the accuracy and efficiency is also provided. the case study demonstrates the good potential of using data analytics for spectral data from miniature device, although the overall performance of those ML classifiers is not exceptional (the classification rates of up to 83.32%) which is partially due to the quality of data, and partially due to limiting to only some classifiers. More elaborate data pre-processing and cleaning methods can be used to address the key challenges of the spectral data from miniature device, and other types
