Comparing Computing Platforms for Deep Learning on a Humanoid Robot

The goal of this study is to test two different computing platforms with respect to their suitability for running deep networks as part of a humanoid robot software system. One of the platforms is the CPU-centered Intel NUC7i7BNH and the other is a NVIDIA Jetson TX2 system that puts more emphasis on GPU processing. The experiments addressed a number of benchmarking tasks including pedestrian detection using deep neural networks. Some of the results were unexpected but demonstrate that platforms exhibit both advantages and disadvantages when taking computational performance and electrical power requirements of such a system into account.Comment: 12 pages, 5 figure

PREDIKSI PENYAKIT STROKE MENGGUNAKAN SUPPORT VECTOR MACHINE (SVM)

Berdasarkan data dari Kementerian Kesehatan Indonesia, telah terjadi peningkatan jumlah pada kasuspenyakit stroke sebesar 3.9% mulai dari tahun 2013 sampai dengan tahun 2018. Secara nasional, jumlahkasus stroke sering terjadi pada kelompok yang memiliki rentang umur antara 55-64 tahun dan palingsedikit terjadi pada rentang umur 15-24. Stroke atau (Cerebrovascular Accidents) merupakan sebuahkeadaan dimana aliran darah ke otak mengalami gangguan mendadak atau berkurang. Hal tersebutdapat disebabkan oleh penyumbatan atau pecah pembuluh darah, sehingga sel-sel pada area otak tidakmendapatkan pasokan darah yang nutrisi dan oksigen. Diperlukan deteksi dini yang bertujuan untukmengurangi jumlah potensi kematian akibat stroke. Prediksi stroke masih menjadi tantang dalam bidangkedokteran, salah satu penyebabnya adalah volume data pada data medis yang memiliki heterogenitasdan kompleksitas yang tinggi. Teknik machine learning merupakan model analisis data yang dapatdigunakan untuk memprediksi penyakit stroke. Berbagai model pembelajaran machine learning telahdiusulkan oleh peneliti-peneliti sebelumnya, salah satunya Support Vector Machine. Penelitian inimencoba menerapkan kembali algoritma SVM dengan mendapatkan hasil kinerja lebih baik daripenelitian sebelumnya. Dalam penelitian ini didapatkan nilai accuracy sebesar 100% dan nilai ROC-AUC sebesar 100%. Perlu dilakukan pengkajian lagi terkait hasil yang didapatkan hingga mencapai100%

An Integrative Paradigm for Enhanced Stroke Prediction: Synergizing XGBoost and xDeepFM Algorithms

Stroke prediction plays a crucial role in preventing and managing this debilitating condition. In this study, we address the challenge of stroke prediction using a comprehensive dataset, and propose an ensemble model that combines the power of XGBoost and xDeepFM algorithms. Our work aims to improve upon existing stroke prediction models by achieving higher accuracy and robustness. Through rigorous experimentation, we validate the effectiveness of our ensemble model using the AUC metric. Through comparing our findings with those of other models in the field, we gain valuable insights into the merits and drawbacks of various approaches. This, in turn, contributes significantly to the progress of machine learning and deep learning techniques specifically in the domain of stroke prediction

Early Classifying Multimodal Sequences

Often pieces of information are received sequentially over time. When did one collect enough such pieces to classify? Trading wait time for decision certainty leads to early classification problems that have recently gained attention as a means of adapting classification to more dynamic environments. However, so far results have been limited to unimodal sequences. In this pilot study, we expand into early classifying multimodal sequences by combining existing methods. We show our new method yields experimental AUC advantages of up to 8.7%.Comment: 7 pages, 5 figure

Spoken Language Identification System for English-Mandarin Code-Switching Child-Directed Speech

This work focuses on improving the Spoken Language Identification (LangId) system for a challenge that focuses on developing robust language identification systems that are reliable for non-standard, accented (Singaporean accent), spontaneous code-switched, and child-directed speech collected via Zoom. We propose a two-stage Encoder-Decoder-based E2E model. The encoder module consists of 1D depth-wise separable convolutions with Squeeze-and-Excitation (SE) layers with a global context. The decoder module uses an attentive temporal pooling mechanism to get fixed length time-independent feature representation. The total number of parameters in the model is around 22.1 M, which is relatively light compared to using some large-scale pre-trained speech models. We achieved an EER of 15.6% in the closed track and 11.1% in the open track (baseline system 22.1%). We also curated additional LangId data from YouTube videos (having Singaporean speakers), which will be released for public use.Comment: Accepted by Interspeech 2023, 5 pages, 1 figure, 4 table
