TL;DR: In this article, a minimalist account of the distribution of the features of case, number and gender in Polish phrases with cardinal numerals and vague quantifiers (Q-NPs) in the presence and absence of genitive of quantification is presented.
Abstract: This paper offers a minimalist account of the distribution of the features of case, number and gender in Polish phrases with cardinal numerals and vague quantifiers (Q-NPs) in the presence and absence of genitive of quantification (GQ) based on the assumption that GQ-cardinal numerals and vague quantifiers are phrasal and are merged as adjuncts to the projection of a null functional head (F), a phase head that values its complement with GQ in contexts in which GQ is not overridden by inherent theta-related or lexical case. Whether the null head F inserted in the derivation has unvalued features of number and gender has consequences for the syntactic computation of agreement relations, in which features may be shared. Heterogeneous case distribution in Q-NPs in nominative-accusative case contexts provides evidence that F is a phase head and triggers transfer of its complement. Variable agreement patterns of both attributive adjectival modifiers and adjectival predicates in the presence of GQ are argued here to reflect attempted-but-failed syntactic agreement, which does not lead to ungrammaticality, as some features unvalued in narrow syntax can still be interpreted by morphological realization rules in PF. GQ is shown here to provide evidence that predicative adjectives cannot have their φ-features valued in situ and must be remerged in a position where their φ-probes can initiate Search for matching features. Agreement in the presence of GQ in Polish thus demonstrates that the need of features to be valued drives syntactic movement

TL;DR: A Double-Head method is proposed, which has a fully connected head focusing on classification and a convolution head to pay more attention to bounding box regression for the unfocused tasks.
Abstract: Two head structures (i.e. fully connected head and convolution head) have been widely used in R-CNN based detectors for classification and localization tasks. However, there is a lack of understanding of how does these two head structures work for these two tasks. To address this issue, we perform a thorough analysis and find an interesting fact that the two head structures have opposite preferences towards the two tasks. Specifically, the fully connected head (fc-head) is more suitable for the classification task, while the convolution head (conv-head) is more suitable for the localization task. Furthermore, we examine the output feature maps of both heads and find that fc-head has more spatial sensitivity than conv-head. Thus, fc-head has more capability to distinguish a complete object from part of an object, but is not robust to regress the whole object. Based upon these findings, we propose a Double-Head method, which has a fully connected head focusing on classification and a convolution head for bounding box regression. Without bells and whistles, our method gains +3.5 and +2.8 AP on MS COCO dataset from Feature Pyramid Network (FPN) baselines with ResNet-50 and ResNet-101 backbones, respectively.

TL;DR: It is shown that this movement serves to avoid violating locality when the T head tries to enter into a multiple agreement relation with the adjective as well as with the subject.
Abstract: Corver (2009) accounts for the postadjectival placement of the measure phrase in Romance by preposing the adjectival phrase over the measure phrase. I show that this movement serves to avoid violating locality when the T head tries to enter into a multiple agreement relation with the adjective as well as with the subject. I also suggest that the feature content of the potentially intervening measure phrase influences the range of parametric options.
