Transformers have shown improved performance when compared to previous architectures for sequence processing such as RNNs. Despite their sizeable performance gains, as recently suggested, the model is computationally expensive to train and with a hig
h parameter budget. In light of this, we explore parameter-sharing methods in Transformers with a specific focus on generative models. We perform an analysis of different parameter sharing/reduction methods and develop the Subformer. Our model combines sandwich-style parameter sharing, which overcomes naive cross-layer parameter sharing in generative models, and self-attentive embedding factorization (SAFE). Experiments on machine translation, abstractive summarization and language modeling show that the Subformer can outperform the Transformer even when using significantly fewer parameters.
Despite their success, modern language models are fragile. Even small changes in their training pipeline can lead to unexpected results. We study this phenomenon by examining the robustness of ALBERT (Lan et al., 2020) in combination with Stochastic
Weight Averaging (SWA)---a cheap way of ensembling---on a sentiment analysis task (SST-2). In particular, we analyze SWA's stability via CheckList criteria (Ribeiro et al., 2020), examining the agreement on errors made by models differing only in their random seed. We hypothesize that SWA is more stable because it ensembles model snapshots taken along the gradient descent trajectory. We quantify stability by comparing the models' mistakes with Fleiss' Kappa (Fleiss, 1971) and overlap ratio scores. We find that SWA reduces error rates in general; yet the models still suffer from their own distinct biases (according to CheckList).
This research has studied some of the physical properties for
Castanea sativa Mill. And Quercus cerris subsp. Pseudocerris, which
have small diameters resulting from the processes of breeding and
development and are related to the most important uses of modern
wood.
This investigation was carried out in the fields and laboratories of Pome and
Grapevine Department, GCSAR/Syria, on some apple varieties i.e. Richared,
Mutsu and Tourly Winsap to determine the optimal harvest date and its effect on
storability. Fr
uits were harvested in (16/9, 26/9, 7/10, 17/10 and 30/10) depending
on physical and chemical maturity indicators, and stored with the study of changing
in quality indicators and weight lost monthly. The results showed that the studied
varieties differed in their storability according to harvest date, Richared fruits in
26/9 showed long storage for seven months with weight loss of 4.9%, fruit firmness
6.4 kg/cm2, and 18.7% TSS. While the storability was six months for Mutsu fruits
which harvested in 7/10 with weight loss of 4.4%, and fruit firmness 6.1 kg/cm2,
and finally, Tourly Winsap fruits which were stored for five months in 7 and 17/10
harvest dates with fruit firmness 5.1 kg/cm2. Moreover, the three varieties were able
to storage for three months when harvested in 30/10 with weight loss of 3.3%, 4.4%
and 4.5% in Tourly Winsap, Richared and Mutsu respectively, which considered
as consuming maturity for these varieties. These results indicated to the various
storage periods according to fruits harvest time, and the storability, which assists
in regulating offer and demand, and providing markets with fruits for long period,
however harvesting at optimal time reducing the total weight loss, in addition to
high quality indicators.
This study was conducted during the period 2014-2016 in the nursery College of
Agriculture, University of Tishreen, this study aimed to calculate the percentage of
germination of the seeds of Laurus nobilis and Pinus pinea using different proportio
ns of
olive cake with a mixture Arboretum, and study some of the planter resulting properties as
well as some physical and chemical characteristics of agricultural mixture that used. were
analyzed using spss statistical program
The mixing nursery soil (sand, soil 1: 1) with olive cake rates (25,50,75,100)% .
assessment: germination percentage, wet and dry weight of shoot and root grouped,
volumetric weight, moisture middle and chemical characteristics. , For germination
percentage it has increased every germination of seeds of laurel and pine fruiting increase
the proportion of bagasse in the agricultural center in general ratio, and on the contrary has
increased wet weight of shoots with decreasing proportion of olive cake in both types
studied. For the physical properties there was a decrease in the volumetric weight of the
agricultural community to increase the proportion of the studied olive cake, as soil
moisture ratio increased to increase the proportion of bagasse. Rich agricultural circles
used container Regarding chemical properties have been observed on the olive cake metal
elements (iron, magnesium and copper), The salinity and acidity remained within normal
limits, so the study has demonstrated the validity of the use of olive cake as a medium for
planting in whole or in part agricultural mixtures used in nurseries.
This search aims to study the efficiency of using“Biotolerance” as a
fertiliser; by a foliar spry on Pepper seedling. Four varieties were
used (Marcony, California wander, Maroty-7 andRobber). The
results showed that the treatment by the fertilizer resulted in an
increase in growth thorough the plant length increasing.
The corrosion inhibition of transmision steel in 1M HCl solution in
the presence of Vanillin at temperature (20,30,40,50,60)°C at
concentration between (100-500) ppm for two hours were studied
using weight loss method.
A total of 300 one day old chicks (150 Commercial broiler
chicks,150 local Syrian chicks) were raised for 6 weeks in order to
measure blood concentration of Growth hormone ,There were 2
treatments 3 replications for each. At the end of every week
6 birds
were weighed and bled in order to examine growth hormone.
The current investigation was conducted to study some
productive properties( body weight, body weight gain, feed intake,
feed conversion ratio, carcass composition, and carcass cuts ) on
some broiler strains in Syria ( Ross, Hubbard, and Shefer ).
The study was excuted in Latakia governorate during the period (2014-2015). In this
study, it has been used three cultivars of Eriobotrya japonica which were Seedawi,
Morocan and Municipal). Onfigurable characterization, the average fruit weight ca
lculation
and the average number of seeds have been done of the fruit. Some chemical analysis were
also conducted of the juice. The data has been statistical analyzed and the results showed
that the earliest cultivar in maturity was Municipal. The highest rate of average fruit s
weight was (53.40g) in Morocan cultivar. And the fruits shapes were between the oval
shape in the Morocan and Seedawi cultivar, and circular shape in the Municipal cultivar.
The Morocan and Seedawi cultivars have the supremacy in production quantity(34.67-34
kg/tree) respectively at the Municipal. The highest proportion was in vitamin C, the acidity
and sugars were (0.977,1.073,15.20 %) respectively in municipal cultivar.
