Social media are a rich source of user generated content where people express their views towards the products and services they encounter. However, sentiment analysis using machine learning models are not easy to implement in a time and cost effective manner due to the requirement of expert human annotators to label the training data. The proposed approach uses a novel method to remove the neutral statements using a combination of lexicon based approach and human effort. This is followed by using a deep active learning model to perform sentiment analysis to reduce annotation efforts. It is compared with the baseline approach representing the neutral tweets also as a part of the data. Considering brands require aspect based ratings towards their products or services, the proposed approach also categorizes predicting ratings of each aspect of mobile device.

EN
This paper concerns the retrieval of audio samples with a high degree of user interaction, motivated by a practical use case. We consider an open set recognition scenario in which the goal is to find all occurrences of a subjectively interesting sound selected by a user within a particular audio file. We use only a single starting example and maintain interaction through yes-no answers from the user, indicating whether any new retrieved sound matches the target pattern. We present a small dataset for this task and evaluate a baseline solution based on Nonnegative Matrix Factorization and greedy feature selection.

The need to match education and business goals is an endeavour and a challenge for any educational institution, especially for higher education institutions. This challenge has become an important focus over the last decades due to the claimed relationship between education and innovation as well as the potential for economic development. The biggest challenge seems to be to overcome the barriers of thought and objectives that exist between the two worlds of education and business. Indeed, although many attempts and programmes are being developed almost all over the world to bridge these two realities, many clashes and disillusions exist. For different reasons, this issue is viewed almost exclusively from the academic perspective, with the entrepreneurial perspective being completely absent. Based on the experience of both the academic and business worlds, the authors commence this contribution by analysing the causes of this mismatch of interests. They conclude by presenting some possible solutions for improving this misalignment.

On examples of teaching introductory courses on digital design, the article summarizes four years of the author’s experience in using active teaching and learning methods in engineering education. The results of a number of pedagogical experiments showed that: 1) active strategies lead to higher attendance in lectures and a noticeable improvement in student performance; 2) reducing course content and slide presentations in favor of more active teaching style is greatly welcomed by students and has positive influence on learning outcomes; 3) “Concept Inventories” standards allow for defining the minimum course content and identifying gaps in conceptual understanding; and 4) a significant improvement of learning outcomes can be obtained using dedicated video mini-lectures available to students online.

In the field of education, the importance of active learning as a more effective educational method has recently been noted. The element of active learning was introduced to the anchoring training of the training ship for third-year students of Tokyo University of Marine Science and Technology, and its effects have been verified. The learning effect of training was confirmed by the questionnaire results of the students. Moreover, the self-evaluations of student and evaluation of instructor confirmed the skill of grasping a ship's position with improved accuracy and learning effects. Self-evaluation and evaluation by the other student, which were introduced as the element of active learning, both demonstrated a positive learning effect. Furthermore, since an effective training method was examined, a result is reported.

Active learning is the process in which unlabeled instances are dynamically selected for expert labelling, and then a classifier is trained on the labeled data. Active learning is particularly useful when there is a large set of unlabeled instances, and acquiring a label is costly. In business scenarios such as direct marketing, active learning can be used to indicate which customer to approach such that the potential benefit from the approached customer can cover the cost of approach. This paper presents a new algorithm for cost-sensitive active learning using a conditional expectation estimator. The new estimator focuses on acquisitions that are likely to improve the profit. Moreover, we investigate simulated annealing techniques to combine exploration with exploitation in the classifier construction. Using five evaluation metrics, we evaluated the algorithm on four benchmark datasets. The results demonstrate the superiority of the proposed method compared to other algorithms.
