In order to alleviate the huge demand for annotated datasets for different tasks, many recent natural language processing datasets have adopted automated pipelines for fast-tracking usable data. However, model training with such datasets poses a chal
lenge because popular optimization objectives are not robust to label noise induced in the annotation generation process. Several noise-robust losses have been proposed and evaluated on tasks in computer vision, but they generally use a single dataset-wise hyperparamter to control the strength of noise resistance. This work proposes novel instance-adaptive training frameworks to change single dataset-wise hyperparameters of noise resistance in such losses to be instance-wise. Such instance-wise noise resistance hyperparameters are predicted by special instance-level label quality predictors, which are trained along with the main classification models. Experiments on noisy and corrupted NLP datasets show that proposed instance-adaptive training frameworks help increase the noise-robustness provided by such losses, promoting the use of the frameworks and associated losses in NLP models trained with noisy data.
The research looks at the image of the ideal man represented by the
character of prophet Mohammed (pba) that is dealt with by Imam Ali in
'NahjulBalaghah' .
The research begins by showing the opinion of some philosophers in
man in general and the
ideal man in particular . then , it moves to deal with
'the ideal man' . the idea that occupies most of the research .it studies that in
accordance with a preface which refines the characteristics of Prophet
Mohammed supervened by one of Imam Ali`s speeches in which he mentions
the characteristics of the prophet (pba)to make it abvious the characteristics of
the ideal man or what the expected image of man should be that's all done in a
mere, distinct , technical , linguistic from .
the research sheds alight on man's different deeds and his multi –
aspect elements prevailing the appealing aspects in the speech and the impact
of technical images , the language , the cadence in exposing the image of the
ideal man- the prophet himself making its context and the speech it put within
very clear .
This study has aimed to investigate the effectiveness of using negative example on
the acquiring of some scientific concepts for the kindergarteners.
To achieve the research objectives, scientific activities and pictured scientific
concepts test w
ere used.
The study reached the following results:
1. There are no significant differences at (a = 0,05) between the mean scores of the
experimental and control groups on acquiring scientific conceptsin pre-application.
2. There are significant differences at (a = 0,05) between the meanscores of the
experimental and control groups on acquiring scientific concepts in post-application. The
results were in favor of the experimental group.
3. The effectiveness of negative example on the acquiring of some scientific concepts
for the kindergarteners.
Finally, the study is ended with some conclusions and recommendations aspaying the
necessary attentionto the kindergartners’acquisition of scientific concepts and the use of
negative examples when presented.
