A Novel Sound Reconstruction Technique based on a Spike Code (event) Representation

This thesis focuses on the re-generation of sound from a spike based coding system. Three different types of spike based coding system have been analyzed. Two of them are biologically inspired spike based coding systems i.e. the spikes are generated in a similar way to how our auditory nerves generate spikes. They have been called AN (Auditory Nerve) spikes and AN Onset (Amplitude Modulated Onset) spikes. Sounds have been re-generated from spikes generated by both of those spike coding technique. A related event based coding technique has been developed by Koickal and the sounds have been re-generated from spikes generated by Koickal's spike coding technique and the results are compared. Our brain does not reconstruct sound from the spikes received from auditory nerves, it interprets it. But by reconstructing sounds from these spike coding techniques, we will be able to identify which spike based technique is better and more efficient for coding different types of sounds. Many issues and challenges arise in reconstructing sound from spikes and they are discussed. The AN spike technique generates the most spikes of the techniques tested, followed by Koickal's technique (54.4% lower) and the AN Onset technique (85.6% lower). Both subjective and objective types of testing have been carried out to assess the quality of reconstructed sounds from these three spike coding techniques. Four types of sounds have been used in the subjective test: string, percussion, male voice and female voice. In the objective test, these four types and many other types of sounds have been included. From the results, it has been established that AN spikes generates the best quality of decoded sounds but it produces many more spikes than the others. AN Onset spikes generates better quality of decoded sounds than Koickal's technique for most of sounds except choir type of sounds and noises, however AN Onset spikes produces 68.5% fewer spikes than Koickal's spikes. This provides evidences that AN Onset spikes can outperform Koickal's spikes for most of the sound types

Pengembangan Bahan Ajar Menulis Feature dengan Pendekatan Jurnalistik Sastra

ABTRAK Dalam konteks kekinian, kemampuan menulis feature sangatlah urgen untuk dikuasai mahasiswa. Dikatakan demikian, karena feature adalah tulisan kreatif yang terbit di koran, majalah, radio dan tayangan televisi. Sebagai tulisan kreatif, feature adalah cerita pendek yang diangkat dari realitas objektif, faktual, nyata sebagai rangkaian informasi yang dibangun dari hasil visitasi, konfirmasi, dan adakalanya investigasi. Untuk membangun kemampuan menulis feature di kalangan mahasiswa maka diperlukan bahan ajar berpendekatan jurnalistika sastra. Pendekatan jurnalistik sastra adalah pendekatan yang dimulai dari observasi, investigasi, dan penulisan laporan. Penulisan laporannya mengikuti unsur-unsur penulisan cerita pendek; sudut pandang, plot, karakter, gaya, suasana, dan lokasi peristiwa. Rata-rata hasil pembelajaran menulis feature berpendekatan jurnalistik sastra mahasiswa semester empat Pendidikan Bahasa dan Sastra Indonesia FKIP Universitas Jambi; penulisan intro karangan ‘baik’, 5W1H,  ‘sangat baik’,  pengungkapan pesan moral,  ‘baik’; kemampuan pemaparan dengan gaya cerita pendek (  sudut pandang, plot, karakter, gaya, dialog, suasana, lokasi peristiwa)   ‘baik’; tiga puluh persen  mahasiswa yang mengikuti perkuliahan menulis feature mengirimkan tulisan ke media cetak lokal, semuanya dipublikasi. Kata kunci: feature, jurnalistik sastra, observasi, observasi, publikasi ABTRACT In the contemporary context, the ability to write features is very urgent for students to master. It is said so, because features are creative writing published in newspapers, magazines, radio and television shows. As creative writing, features are short stories based on objective, factual, real realities as a series of information built from the results of visitations, confirmations, and sometimes investigations. To build the ability to write features among students, teaching materials with a literary journalistic approach are needed. The literary journalistic approach is an approach that starts from observation, investigation, and report writing. The writing of the report follows the elements of short story writing; point of view, plot, characters, style, atmosphere and location of events. The average learning outcomes of feature writing in the literary journalistic approach of fourth semester students of Indonesian Language and Literature Education FKIP Jambi University; intro writing of 'good', 5W1H, 'very good', expressing moral messages, 'good'; ability to describe short story style (point of view, plot, character, style, dialogue, atmosphere, location of events) 'good'; Thirty percent of students who take feature writing courses send their articles to local print media, all of which are published. Keywords: feature, literary journalism, observation, observation, publicatio

Pelatihan Penulisan Karya Ilmiah Bagi Guru Profesional

Guru seharusnya memiliki  kemampuan menulis untuk menunjang keberhasilan profesinya, karena guru dalam fungsinya sebagai penggali dan penerus ilmu pengetahuan kepada murid-murid tidak cukup hanya disampaikan secara lisan, tetapi juga melalui tulisan.   Permasalahan klasik yang dihadapi guru yaitu rendahnya produktivitas menulis karya ilmiah. Keadaan ini disebabkan guru-guru selama ini dalam mencapai golongan IV/b diyakini  tidak mampu menulis karya ilmiah.  Untuk memenuhi kebutuhan meningkatkan budaya menulis karya ilmiah,  guru harus memahami apa itu karya ilmiah serta seluk beluknya,    baik secara berkelompok maupun individu. Salah satu cara untuk meningkatkan keterampilan guru menulis karya ilmiah adalah melalui pelatihan  yang meliputi: 1) Writing down; latihan melibatkan  proses   reproduksi bahan yang sudah dipelajari; berkosentrasi pada ejaan dan tanda baca. 2) Writing in Language; peserta     pelatihan  terlihat   dalam berbagai aktivitas penerapan aturan tatabahasa. 3) Fleksibilitas; peserta pelatihan mulai menulis dalam suatu kerangka, seperti latihan  tranformasi, penggabungan kalimat, perluasan kalimat.4) Menulis ekpresisf;  peserta menulis artikel terbimbing dan bebas serta pelatihan mengirim artikel ke jurnal ilmiah terakreditasi. Selain itu, luaran yang dihasilkan guru-guru adalah publikasi  artikel ilmiah pada jurnal ilmiah terakreditasi

Deep Transfer Learning based COVID-19 Detection in Cough, Breath and Speech using Bottleneck Features

We present an experimental investigation into the automatic detection of COVID-19 from coughs, breaths and speech as this type of screening is non-contact, does not require specialist medical expertise or laboratory facilities and can easily be deployed on inexpensive consumer hardware. Smartphone recordings of cough, breath and speech from subjects around the globe are used for classification by seven standard machine learning classifiers using leave-$p$-out cross-validation to provide a promising baseline performance. Then, a diverse dataset of 10.29 hours of cough, sneeze, speech and noise audio recordings are used to pre-train a CNN, LSTM and Resnet50 classifier and fine tuned the model to enhance the performance even further. We have also extracted the bottleneck features from these pre-trained models by removing the final-two layers and used them as an input to the LR, SVM, MLP and KNN classifiers to detect COVID-19 signature. The highest AUC of 0.98 was achieved using a transfer learning based Resnet50 architecture on coughs from Coswara dataset. The highest AUC of 0.94 and 0.92 was achieved from an SVM run on the bottleneck features extracted from the breaths from Coswara dataset and speech recordings from ComParE dataset. We conclude that among all vocal audio, coughs carry the strongest COVID-19 signature followed by breath and speech and using transfer learning improves the classifier performance with higher AUC and lower variance across the cross-validation folds. Although these signatures are not perceivable by human ear, machine learning based COVID-19 detection is possible from vocal audio recorded via smartphone
