Order-free Learning Alleviating Exposure Bias in Multi-label Classification
Multi-label classification (MLC) assigns multiple labels to each sample.
Prior studies show that MLC can be transformed to a sequence prediction problem
with a recurrent neural network (RNN) decoder to model the label dependency.
However, training a RNN decoder requires a predefined order of labels, which is
not directly available in the MLC specification. Besides, RNN thus trained
tends to overfit the label combinations in the training set and have difficulty
generating unseen label sequences. In this paper, we propose a new framework
for MLC which does not rely on a predefined label order and thus alleviates
exposure bias. The experimental results on three multi-label classification
benchmark datasets show that our method outperforms competitive baselines by a
large margin. We also find the proposed approach has a higher probability of
generating label combinations not seen during training than the baseline
models. The result shows that the proposed approach has better generalization
capability
Why We Should Report the Details in Subjective Evaluation of TTS More Rigorously
This paper emphasizes the importance of reporting experiment details in
subjective evaluations and demonstrates how such details can significantly
impact evaluation results in the field of speech synthesis. Through an analysis
of 80 papers presented at INTERSPEECH 2022, we find a lack of thorough
reporting on critical details such as evaluator recruitment and filtering,
instructions and payments, and the geographic and linguistic backgrounds of
evaluators. To illustrate the effect of these details on evaluation outcomes,
we conducted mean opinion score (MOS) tests on three well-known TTS systems
under different evaluation settings and we obtain at least three distinct
rankings of TTS models. We urge the community to report experiment details in
subjective evaluations to improve the reliability and interpretability of
experimental results.Comment: Interspeech 2023 camera-ready versio
Alternative Ingredient Recommendation: A Co-occurrence and Ingredient Category Importance Based Approach
As many people will refer to a recipe when cooking, there are several recipe-sharing websites that include lots of recipes and make recipes easier to access than before. However, there is often the case that we could not get all the ingredients listed on the recipe. Prior research on alternative ingredient substitution has built a recommendation system considering the suitability of a recommended ingredient with the remained ingredients. In this paper, in addition to suitability, we also take the diversity of the ingredient categories and the novelty of new combination of ingredients into account. Besides, we combine suitability with novelty as an index, to see whether our method could help find out a new combination of ingredients that is possibly to be a new dish. Our evaluation results show that our proposed method attains a comparable or even better performance on each perspective
Modulation of Serum Antinuclear Antibody Levels by Levamisole Treatment in Patients With Oral Lichen Planus
Background/PurposeSerum autoantibodies, including antinuclear antibodies (ANAs), have been found in patients with oral lichen planus (OLP). This study evaluated whether Taiwanese OLP patients had significantly higher frequencies of serum ANAs than healthy control subjects, and whether levamisole treatment could modulate the antibody levels.MethodsThis study used an indirect immunofluorescence technique to measure the baseline serum levels of ANA in a group of 583 Taiwanese OLP patients and 53 healthy control subjects. Seventy-nine ANA-positive OLP patients were treated with levamisole under a regular follow-up schedule in our dental clinic, and their serum ANA levels were measured after treatment.ResultsWe found that the frequencies of serum ANA in patients with OLP (23.2%), erosive OLP (EOLP, 23.8%), major EOLP (31.5%), and minor EOLP (18.1%) were all significantly higher than that (5.7%) in healthy control subjects. In addition, major EOLP patients had a significantly higher serum ANA positive rate than minor EOLP or non-erosive OLP patients. Of 135 ANA-positive OLP patients, 79 were treated with levamisole under a regular follow-up schedule. We found that treatment with levamisole for a period of 2–38 months (mean, 12 ± 9 months) effectively reduced the high mean serum ANA titer (557 ± 98) at baseline to an undetectable level (0) in all ANA-positive OLP patients, regardless of different high initial serum titers of ANA.ConclusionThere was a significantly higher frequency of serum ANA (23.2%) in Taiwanese OLP patients than in healthy control subjects. Treatment with levamisole for 2–38 months reduced the high serum ANA to an undetectable level, and significantly improved the signs and symptoms in all treated OLP patients
