Enhancing multimedia management: cloud-based movie type recognition with hybrid deep learning architecture

Film and movie genres play a pivotal role in captivating relevant audiences across interactive multimedia platforms. With a focus on entertainment, streaming providers are increasingly prioritizing the automatic generation of movie genres within cloud-based media services. In service management, the integration of a hybrid convolutional network proves to be instrumental in effectively distinguishing between a diverse array of video genres. This classification process not only facilitates more refined recommendations and content filtering but also enables targeted advertising. Furthermore, given the frequent amalgamation of components from various genres in cinema, there arises a need for social media networks to incorporate real-time video classification mechanisms for accurate genre identification. In this study, we propose a novel architecture leveraging deep learning techniques for the detection and classification of genres in video films. Our approach entails the utilization of a bidirectional long- and short-term memory (BiLSTM) network, augmented with video descriptors extracted from EfficientNet-B7, an ImageNet pre-trained convolutional neural network (CNN) model. By employing BiLSTM, the network acquires robust video representations and proficiently categorizes movies into multiple genres. Evaluation on the LMTD dataset demonstrates the substantial improvement in the performance of the movie genre classifier system achieved by our proposed architecture. Notably, our approach achieves both computational efficiency and precision, outperforming even the most sophisticated models. Experimental results reveal that EfficientNet-BiLSTM achieves a precision rate of 93.5%. Furthermore, our proposed architecture attains state-of-the-art performance, as evidenced by its F1 score of 0.9012.

Automatic genre identification: a survey

AbstractAutomatic genre identification (AGI) is a text classification task focused on genres, i.e., text categories defined by the author’s purpose, common function of the text, and the text’s conventional form. Obtaining genre information has been shown to be beneficial for a wide range of disciplines, including linguistics, corpus linguistics, computational linguistics, natural language processing, information retrieval and information security. Consequently, in the past 20 years, numerous researchers have collected genre datasets with the aim to develop an efficient genre classifier. However, their approaches to the definition of genre schemata, data collection and manual annotation vary substantially, resulting in significantly different datasets. As most AGI experiments are dataset-dependent, a sufficient understanding of the differences between the available genre datasets is of great importance for the researchers venturing into this area. In this paper, we present a detailed overview of different approaches to each of the steps of the AGI task, from the definition of the genre concept and the genre schema, to the dataset collection and annotation methods, and, finally, to machine learning strategies. Special focus is dedicated to the description of the most relevant genre schemata and datasets, and details on the availability of all of the datasets are provided. In addition, the paper presents the recent advances in machine learning approaches to automatic genre identification, and concludes with proposing the directions towards developing a stable multilingual genre classifier.

Implementation of Music Genre Classifier Using KNN Algorithm

As music history grew, music began to diversify into different genres. Thisstudy aims to implement a music genre classifier using the KNN algorithm and a faster method. The KNN algorithm is accurate but with long execution time. This study implements a new method that can speed up the process of the KNN algorithm, and the K-means clustering algorithm inspires the idea. The dataset is preprocessed using the new idea. The program will select the song that is the centroid of the genre and use the method of the KNN to return the closest genre based on the distance from the test sample to the centroid. In conclusion, the new method did not perform well in accuracy but sped up the program. This study provides a great reference for the music genre classification problem in the machine learning domain. The study investigates an infeasible method in preprocessing data for the KNN algorithm optimization.

Development of Convolutional Neural Networks for Analyzing Game Icon and Screenshot Images

Icons and screenshots are important media displayed in game distribution platforms for providing a brief understanding of the game content to the customers. In this study, we develop ensemble convolutional neural networks for icon and screenshot analysis as three applications: an automatic genre classification, a similar game searching, and a recognition quality assessment. First, the genre classifier is developed using 154358 images from 18 030 games in 17 genres. The proposed genre classifiers achieve 40.5% and 47.6% accuracies for classifying a single icon and a single screenshot, which outperform the average performance of the human testers. The accuracy can be boosted to 54.2% by aggregating results from every image of the game. The Grad-CAM is applied to analyze what models learned. Then, the feature extraction part trained by this task is transferred to the other two applications. For the similar game searching, a dissimilarity of two images is directly computed by the Euclidean distance in the feature space. We define a dissimilarity between two games which are sets of multiple images based on their image-pairwise dissimilarity. The results show that the features are successfully transferred, and the model seems to be able to cluster the games with a similar gameplay and differentiate them from the other gameplays even if they come from the same genre. For the third application, we develop a system for quality assessment of game images based on the correctness of viewers’ understanding of game content by combining multiple models from three different problem definitions. Our system can identify good-genre-representing game images which most of the human testers can recognize their genre correctly with 75.0% accuracy for icons and 76.2% accuracy for screenshots.

Fast Recognition using Bar-based Data Mapping for Gamelan Music Genre Classification

This research aims to develop a gamelan music genre classifier based on the musical mode system determined based on the dominant notes in a certain order. Only experts can discriminate the musical mode system of compositions. The Feed Forward Neural Networks method was used to classify gamelan compositions into three musical mode systems. The challenge is to recognize the musical mode system of compositions between the initial melody without having to analyze the entire melody using a small amount of data for the dataset. Instead of conducting a melodic extraction from audio signal data, the text-based skeletal melody data, which is a form of extracted melodic features, are used for the dataset. Unique corpuses are controlled based on the cardinality of the one-to-many relationship, and a data mapping technique based on the bars is used to increase the number of corpuses. The results show that the proposed method is suitable to solve the specified problems, where the accuracy in recognizing the class of unseen compositions between the initial melody achieves at 86.7%.

Generative Autoregressive Networks for 3D Dancing Move Synthesis From Music

This letter proposes a framework which is able to generate a sequence of three-dimensional human dance poses for a given music. The proposed framework consists of three components: a music feature encoder, a pose generator, and a music genre classifier. We focus on integrating these components for generating a realistic 3D human dancing move from music, which can be applied to artificial agents and humanoid robots. The trained dance pose generator, which is a generative autoregressive model, is able to synthesize a dance sequence longer than 1,000 pose frames. Experimental results of generated dance sequences from various songs show how the proposed method generates human-like dancing move to a given music. In addition, a generated 3D dance sequence is applied to a humanoid robot, showing that the proposed framework can make a robot to dance just by listening to music.

An effective analysis of deep learning based approaches for audio based feature extraction and its visualization

Visualizations help decipher latent patterns in music and garner a deep understanding of a song’s characteristics. This paper offers a critical analysis of the effectiveness of various state-of-the-art Deep Neural Networks in visualizing music. Several implementations of auto encoders and genre classifiers have been explored for extracting meaningful features from audio tracks. Novel techniques have been devised to map these audio features to parameters that drive visualizations. These methodologies have been designed in a manner that enables the visualizations to be responsive to the music as well as provide unique visual experiences across different songs.

On the Application of Generic Summarization Algorithms to Music

Several generic summarization algorithms were developed in the past and successfully applied in fields such as text and speech summarization. In this paper, we review and apply these algorithms to music. To evaluate this summarization's performance, we adopt an extrinsic approach: we compare a Fado Genre Classifier's performance using truncated contiguous clips against the summaries extracted with those algorithms on 2 different datasets. We show that Maximal Marginal Relevance (MMR), LexRank and Latent Semantic Analysis (LSA) all improve classification performance in both datasets used for testing.

Foreword

The present issue of ALA, the second in its new incarnation, brings two pieces of good news. The first is that it is now also included in the Directory of Open Access Journals (DOAJ), besides Open J-Gate and Google Scholar. The second is that in 2014, the Department of Asian and African Studies of the Faculty of Arts of the University of Ljubljana is going to host the 14th conference of the European Association of Japanese Studies.The focus of this issue is on Chinese and Japanese. Papers devoted to Chinese are more theoretically oriented. In the first paper, David Ta-Chun SHEN argues about which theoretical devices are sufficient to explain the phenomenon in Mandarin where prepositions may or may not undergo the third tone sandhi. The second paper, by Jens KARLSSON, deals with adverbs zai and you in Modern Standard Chinese, showing the similarities of semantic content between the two adverbs and pointing out the main difference between them, i.e. the difference in viewpoint, and possible consequences of this fact.On the other hand, papers devoted to Japanese look at various issues from an applied linguistic perspective. Nagisa MORITOKI, based on her experience of teaching Japanese in Slovenia, discusses the learner and the teacher’s role and their possible strategies when dealing with the vast treasure-trove of information available on the Internet.Next, Bor HODOŠČEK explores genre variation in the newest large-scale modern Japanese language corpus, the BCCWJ, and the usability of modifier-verb ratio as a genre classifier. In the last paper, Irena SRDANOVIĆ and co-authors discuss the issues involved in creating Japanese language word sketches, singling out in particular the lemmatizer, the tagger, the corpus and statistical methods used, and the sketch grammar that is specifically written for Japanese.In this issue’s Book Review, Mateja PETROVČIČ reviews the work by Xiaoqin SU on reflexivity in Chinese, Reflexivität im Chinesischen: Eine IntegrativeAnalyse.

Improving Music Genre Classification Using Automatically Induced Harmony Rules

We present a new genre classification framework using both low-level signal-based features and high-level harmony features. A state-of-the-art statistical genre classifier based on timbral features is extended using a first-order random forest containing for each genre rules derived from harmony or chord sequences. This random forest has been automatically induced, using the first-order logic induction algorithm TILDE, from a dataset, in which for each chord the degree and chord category are identified, and covering classical, jazz and pop genre classes. The audio descriptor-based genre classifier contains 206 features, covering spectral, temporal, energy, and pitch characteristics of the audio signal. The fusion of the harmony-based classifier with the extracted feature vectors is tested on three-genre subsets of the GTZAN and ISMIR04 datasets, which contain 300 and 448 recordings, respectively. Machine learning classifiers were tested using 5 × 5-fold cross-validation and feature selection. Results indicate that the proposed harmony-based rules combined with the timbral descriptor-based genre classification system lead to improved genre classification rates.

Training a Genre Classifier for Automatic Classification of Web Pages

This paper presents experiments on classifying web pages by genre. Firstly, a corpus of 1539 manually labeled web pages was prepared. Secondly, 502 genre features were selected based on the literature and the observation of the corpus. Thirdly, these features were extracted from the corpus to obtain a data set. Finally, two machine learning algorithms, one for induction of decision trees (J48) and one ensemble algorithm (bagging), were trained and tested on the data set. The ensemble algorithm achieved on average 17% better precision and 1.6% better accuracy, but slightly worse recall; F-measure did not vary significantly. The results indicate that classification by genre could be a useful addition to search engines.

Learning to classify documents according to genre

AbstractCurrent document‐retrieval tools succeed in locating large numbers of documents relevant to a given query. While search results may be relevant according to the topic of the documents, it is more difficult to identify which of the relevant documents are most suitable for a particular user. Automatic genre analysis (i.e., the ability to distinguish documents according to style) would be a useful tool for identifying documents that are most suitable for a particular user. We investigate the use of machine learning for automatic genre classification. We introduce the idea of domain transfer—genre classifiers should be reusable across multiple topics—which does not arise in standard text classification. We investigate different features for building genre classifiers and their ability to transfer across multiple‐topic domains. We also show how different feature‐sets can be used in conjunction with each other to improve performance and reduce the number of documents that need to be labeled.
