"The authors conducted 4 repetitio priming experiments that manipulated prime duration and prime diagnocity in a visual forced-choice percceptual identification task. The strength and direction of prime diagnosticty produced marked effects on identification accuracy, but those effects were resistant to subsequent changes of diagnosicity. Participants learned to associate different diagnocities with primes of different durations but not with primes presented in different colors. Regardless of prime diagnosticity, preference for a primed alternative covaried negatively with prime duration, suggesting that even for diagnostic primes, evidence discounting remains an important factor. A computational model, with the assumption that adaptation to the statistics of the experiment modulates the level of evidence discounting, accounted for these results."

"This book investigates the fascinating concept of a continuum between human memory and memory of materials. The first part provides state-of-the-art information on shape memory alloys and outlines a brief history of memory from the ancient Greeks to the present day, describing phenomenological, philosophical, and technical approaches such as neuroscience. Then, using a wealth of anecdotes, data from academic literature, and original research, this short book discusses the concepts of post-memory, memristors and forgiveness, highlights the analogies between materials defects and memory traces in the human brain. Lastly, it tackles questions of how human memory and memory of materials work together and interact. With insights from materials mechanics, neuroscience and philosophy, it enables readers to understand and continue this open debate on human memory."

"Banyak sekali variabel nonlinear didalam sistem kendali untuk quadcopter sehingga cukup rumit untuk mengendalikan dinamika penerbangan dari wahana ini. Salah satu metode yang digunakan untuk membangun model dinamik quadcopter adalah Deep Learning berbasis Long Short-Term Memory. Metode pembelajaran yang umum digunakan dalam melatih model adalah offline learning, dimana pelatihan dilakukan secara akumulatif berdasarkan dataset yang telah dimiliki. Walaupun offline learning memungkinkan model belajar lebih cepat, metode ini menghasilkan model yang kurang baik untuk wahana yang membutuhkan feedback dengan kompleksitas tinggi. Untuk menangani masalah tersebut akan dikembangkan metode online learning, dimana data diperoleh secara sekuensial dan digunakan untuk memperbarui model di setiap timestep. Akan ditunjukkan bahwa metode online learning dapat memperbaiki model yang diperoleh dari metode offline learning berdasarkan Mean Square Error dari setiap jenis data quadcopter.
..... There are so many nonlinear variables in the control system for the quadcopter so it is quite complicated to control the flight dynamics of this vehicle. One of the methods used to build a dynamic quadcopter model is Deep Learning based on Long Short-Term Memory. The learning method commonly used in training the model is offline learning, where training is carried out accumulatively based on the existing dataset. Although offline learning allows for faster learning models, this method results in poor models for vehicles that require high complexity feedback. To deal with this problem, an online learning method will be developed, where data is obtained sequentially and used to update the model at each time step. It will be shown that the online learning method can improve the model obtained from the offline learning method based on the Mean Square Error of each quadcopter data type."

"Pesatnya perkembangan teknologi saat ini menjadi salah satu faktor berkembangnya media sosial. Pengguna media sosial khususnya di Indonesia sudah tidak diragukan lagi jumlahnya. Dari tingginya tingkat penggunaan media sosial, penelitian terkait data pada media sosial kerap dilakukan. Penelitian yang populer dilakukan adalah analisis sentimen. Analisis sentimen adalah kegiatan untuk mengklasifikasikan sentimen data tekstual ke dalam kelas positif atau negatif. Metode yang kerap digunakan adalah metode berbasis machine learning yaitu Convolutional Neural Network (CNN) dan Long-short Term Memory (LSTM). Metode CNN sudah terbukti baik digunakan untuk data tekstual. Adapun model gabungan yaitu LSTM-CNN yang sudah terbukti memberikan hasil lebih baik dibanding model CNN. Selanjutnya akan dilakukan analisis sentimen menggunakan model LSTM-CNN. Namun, metode berbasis machine learning hanya efektif digunakan pada satu domain saja. Berdasarkan hal tersebut, dikembangkanlah lifelong learning. Lifelong learning adalah metode dalam machine learning yang menerapkan pembelajaran berkelanjutan terhadap lebih dari satu domain. Lifelong learning pada machine learning meniru bagaimana manusia mempelajari sesuatu berdasarkan apa yang sudah dipelajari selanjutnya. Pada skripsi ini, akan dilakukan penelitian model LSTM-CNN untuk permasalahan lifelong learning analisis sentimen terhadap lima data berbahasa Indonesia. Lima data set tersebut akan digunakan sebagai data pembelajaran secara berkelanjutan terhadap suatu model LSTM-CNN. Evaluasi model akan dilakukan pada setiap proses pembelajaran yang dilakukan. Hasil yang diperoleh adalah perkembangan akurasi pada setiap proses pembelajaran terhadap suatu data set.

The rapid development of technology is currently one of the factors in the development of social media. There are no doubt about the number of social media users, especially in Indonesia. From the high level of use of social media, research related to data on social media is often done. Popular research is sentiment analysis. Sentiment analysis is an activity to classify textual data sentiments into positive or negative classes. The method often used is machine learning-based methods, namely Convolutional Neural Network (CNN) and Long-short Term Memory (LSTM). The CNN method has been proven good for textual data. The combined model is LSTM-CNN which has been proven to provide better results than the CNN model. Then sentiment analysis will be performed using the LSTM-CNN model. However, machine learning based methods are only effective in one domain. Based on this, lifelong learning was developed. Lifelong learning is a method in machine learning that applies continuous learning to more than one domain. Lifelong learning in machine learning mimics how humans learn something based on what has been learned next. In this thesis, LSTM-CNN model research will be conducted for the problem of lifelong learning sentiment analysis of five Indonesian-language data. The five data sets will be used as continuous learning data on an LSTM-CNN model. Evaluation of the model will be carried out in each learning process that is carried out. The results obtained are the development of accuracy in each learning process of a data set."

"Analisis sentimen merupakan suatu proses untuk menentukan sikap atau sentimen dari penulis mengenai hal tertentu. Proses pengelompokan sentimen secara manual membutuhkan waktu cukup lama, sehingga diusulkan untuk menggunakan machine learning. Pada penelitian ini, model machine learning yang digunakan merupakan model CNN-BiLSTM (Convolutional Neural Network - Bidirectional Long Short-Term Memory) dan BiLSTM-CNN (Bidirectional Long Short-Term Memory - Convolutional Neural Network) yang menghasilkan kinerja yang lebih baik dibandingkan model CNN dan BiLSTM pada permasalahan analisis sentimen. Supaya model dapat belajar secara berkelanjutan dari beberapa domain data, model tersebut juga diimplementasikan lifelong learning. Hasilnya, model CNN-BiLSTM menunjukkan kinerja transfer of knowledge yang lebih baik dibandingkan oleh model BiLSTM-CNN maupun model dasarnya. Di sisi lain, model BiLSTM-CNN menunjukkan kinerja yang lebih buruk dibandingkan model dasarnya. Sedangkan, hasil loss of knowledge menunjukkan bahwa kinerja model CNN- BiLSTM lebih buruk dari BiLSTM-CNN. Selain itu, kedua model gabungan tersebut menunjukkan kinerja yang lebih baik dibandingkan model CNN, tetapi lebih buruk dibandingkan model BiLSTM. Untuk pengembangan lebih lanjut, diimplementasikan pula lifelong learning dengan pembaruan vocabulary. Dengan implementasi tersebut, model mampu mempelajari vocabulary dari domain data 2, 3, 4, dan 5. Pembaruan vocabulary ternyata meningkatkan kinerja model pada transfer of knowledge dan loss of knowledge.

Sentiment analysis is a process to determine the attitude or sentiment of the author regarding certain matters. The process of classifying sentiments manually takes a long time, so it is proposed to use machine learning. In this study, the machine learning model used is the CNN-BiLSTM (Convolutional Neural Network - Bidirectional Long Short-Term Memory) and BiLSTM-CNN (Bidirectional Long Short-Term Memory - Convolutional Neural Network) models which produce better performance than the CNN and BiLSTM models on the problem of sentiment analysis. In order for the model to learn continuously from several data domains, the model is also implemented lifelong learning. As a result, the CNN-BiLSTM model shows better transfer of knowledge performance compared to the BiLSTM-CNN model and its base model. On the other hand, the BiLSTM-CNN model shows a worse performance than its base model. Meanwhile, the results of loss of knowledge show that the performance of the CNN-BiLSTM model is worse than the BiLSTM-CNN model. In addition, the two combined models show better performance than the CNN model, but worse than the BiLSTM model. For further development, lifelong learning is also implemented with an update to vocabulary. With this implementation, the model is able to learn vocabulary from data domain 2, 3, 4, and 5. In fact, the vocabulary update has an effect in increasing the performances of transfer of knowledge and loss of knowledge.
