A Practitioners' Guide to Transfer Learning for Text Classification using Convolutional Neural Networks

Transfer Learning (TL) plays a crucial role when a given dataset has insufficient labeled examples to train an accurate model. In such scenarios, the knowledge accumulated within a model pre-trained on a source dataset can be transferred to a target dataset, resulting in the improvement of the target model. Though TL is found to be successful in the realm of image-based applications, its impact and practical use in Natural Language Processing (NLP) applications is still a subject of research. Due to their hierarchical architecture, Deep Neural Networks (DNN) provide flexibility and customization in adjusting their parameters and depth of layers, thereby forming an apt area for exploiting the use of TL. In this paper, we report the results and conclusions obtained from extensive empirical experiments using a Convolutional Neural Network (CNN) and try to uncover thumb rules to ensure a successful positive transfer. In addition, we also highlight the flawed means that could lead to a negative transfer. We explore the transferability of various layers and describe the effect of varying hyper-parameters on the transfer performance. Also, we present a comparison of accuracy value and model size against state-of-the-art methods. Finally, we derive inferences from the empirical results and provide best practices to achieve a successful positive transfer.Comment: 9 pages, 2 figures, accepted in SDM 201

The Handling and Re-Management of the Product Failed in the Production Process of PT Kedawung Setia

PT Kedawung Setia Industrial Tbk manufactures and sells enamel products in Indonesia. Founded in 1973 and headquartered in Surabaya, Indonesia. PT Kedawung Setia main products are pot and household appliances lined with enamel. Enamel is a kind of special paint that makes the kitchen equipment become colorful so that is better seen and impress ‘luxury'. PT Kedawung Setia does not produce ordinary kitchen utensils, but rather a high-end kitchen appliances to be exported and able to be bought in large supermarkets. Thus it is certainly important for PT. Kedawung Setia to really pay attention to every detail of its production steps to minimize the occurrence of production failure. However the product defect seems to be quite difficult to avoid and still a problem that is putting a risk to the company. This paper aims to analyze the problem in production and display alternative solutions to reduce production failure which causes defect products. The result shows that it can be done via re-management of the defect product to be a new product with good quality adding up a diversification of products for the company

Low-temperature critical current of Y1-xCaxBa2Cu3O7-delta thin films as a function of hole content and oxygen deficiency

The effects of hole content (p) and oxygen deficiency (delta) on the zero-field critical current density, Jc0, were investigated for high-quality c-axis oriented Y1-xCaxBa2Cu3O7-delta (x = 0, 0.05, 0.10, and 0.20) thin films. Ca was used to introduce hole carriers in the CuO2 planes, independent of the oxygen deficiency in the CuO1-delta chains. Low-temperature Jc0(16K) of these films above the optimum doping were found to be high (> 10^7 Amp/cm^2) and were primarily determined by the hole concentration, reaching a maximum at p ~ 0.185+/-0.005, irrespective of oxygen deficiency. This implies that oxygen disorder plays only a secondary role and the intrinsic Jc0 is mainly governed by the carrier concentration and consequently by the superconducting condensation energy which also peaks at p ~ 0.19 where the pseudogap correlation vanishes

Composition variation in essential oils of Artemisia nilagirica and Artemisia capillaris, growing in India

The present study was aimed to find out the chemical constituents of essential oils of Artemisia nilagirica (Clarke) Pamp. and Artemisia capillaris Thunb. of Asteraceae family, growing in Garhwal region of India. The essential oils were obtained by hydro-distillation and subjected to detailed GC-MS analysis in order to determine the variation in their volatile constituents. While comparing the common constituents in both of the species, the remarkable variation was observed and it was 6.03, 3.251, 2.093, 33.73, 7.573, 15.041 and 8.00% for trans-caryophyllene, DL-limonene, ?-pinene, ?-thujone, ?-myrcene, ?-ocimene and ?-thujone, respectively

Effect of combination treatment of S–amlodipine with peroxisome proliferator-activated receptor agonists on metabolic and cardiovascular parameters in Zucker fa/fa rats

BACKGROUND: Type 2 diabetes is a complex metabolic disorder characterized by hyperglycemia, impaired glucose tolerance and insulin resistance associated with dyslipidemia and hypertension. The available drugs are not sufficiently efficacious in reducing cardiovascular risk and restoring normal glucose metabolism associated with type 2 diabetes as a mono- or a combination therapy. The present study examined the combined effects of an antihypertensive (S-Amlodipine) and an insulin-sensitizing agent, peroxisome proliferator-activated receptor (PPAR) agonists (Pioglitazone and Ragaglitazar), on cardiovascular risk factors in aged diabetic and insulin-resistant Zucker fa/fa rats. METHODS: Following combination treatment for 14 days, blood pressure (BP), serum glucose, total cholesterol and triglycerides were measured. Aortic ring study was conducted to determine the effect of combination treatments on phenylephrine-induced vasoconstriction and acetylcholine (Ach)-induced vasorelaxation. RESULTS: In combination, S-Amlodipine and Pioglitazone significantly reduced blood glucose (115.1 ± 6.6 vs. 81.7 ± 4.2), BP (184.4 ± 5.0 vs. 155.1 ± 5.0), serum triglycerides (362.5 ± 47.5 vs. 211.1 ± 23.7) and glucose intolerance when compared with vehicle treated Zucker fa/fa rats. Similar results were observed with the combination of S-Amlodipine and Ragaglitazar (Triglycerides, 362.5 ± 47.5 vs. 252.34 ± 27.86; BP, 184.4 ± 5.0 vs. 159.0 ± 8.0) except for serum glucose. ACh-induced vasorelaxation in aortic rings was also superior with both of the combinations compared to individual treatment. Furthermore, there was less body weight gain and food intake with S-Amlodipine and Pioglitazone combination in Zucker fa/fa rats. S-Amlodipine itself caused significant reduction in glucose (115.1 ± 6.6 vs. 89.7 ± 2.7) and BP (184.4 ± 5.0 vs. 156.1 ± 4.0) with improvement in insulin sensitivity observed through oral glucose tolerance test. CONCLUSIONS: The results suggest that a combination of PPAR agonists and S-Amlodipine has partial benefits in improving the cardiovascular risk factors such as reduction in triglyceride levels, associated with chronic type 2 diabetes, and therefore may be utilized as an approach for addressing some of these devastating metabolic syndrome complications

Contextualising and Understanding Hybrid Warfare by Pakistan

Post abrogation of Article 370 and deterioration in Indo-Pak relations, Pakistan is running out of options and, therefore, would again attempt to activate, exploit, and consolidate its hybrid resources. This is likely to manifest in activation of sleeper cells, the surge in infiltration, fresh recruitment, recycling of some apprehended/surrendered terrorists, and triggering violent agitations in the hinterland of Jammu & Kashmir (J&K). To predict and prepare for likely threats in the future, it is essential to understand and contextualise the hybrid warfare capabilities of Pakistan
