For example, if students are not acquiring segmenting, the teacher may decide to add more scaffolds, such as cards that the students can move as they segment words, thereby making segmenting instruction more explicit, or provide students with more guided practice.
If most students successfully respond to instruction but a few respond poorly or not at all, the teacher may decide to place these students in a flexible group to receive more intense instruction. The teacher could also choose to provide some individuals with more intense instruction throughout the day to keep them up with their peers.
If the progress-monitoring measures indicate that the first-grade students receiving instruction in phonological awareness lag behind their peers in reading or spelling, the teacher may choose to increase the integrated instruction in letter- sound correspondence and to make stronger the links between segmenting and blending skills and reading.
Brief descriptions of the screening and monitoring measures that have demonstrated validity and reliability through research follow. For each measure, we indicate the grade and purpose for which the measure is appropriate.
Note that some measures are appropriate for more than one grade level and for both screening and monitoring progress. Second Half of Kindergarten; Screen. The measure consists of one form with 10 items requiring students to indicate which of three words represented by pictures have the same first sound as a target word and 10 items that require students to indicate which of four words represented by pictures begins with a different first sound than the other three.
The measure is administered to small groups of 6 to 10 children and is untimed. Students receive raw scores that are normed. This measure strongly predicts which kindergarten students will demonstrate growth in blending and segmenting after small-group phonological awareness instruction.
Five nonwords feg, rit, mub, gof, pid comprise the measure. Students receive one point for each phoneme that they represent correctly in the spelling. This measure strongly predicts which kindergarten students are likely to demonstrate growth in blending after small-group phonological awareness instruction. The measure consists of six rows with five single digits per row on an 8 " x 11 " card. The students are timed as they name the digits as fast as they can, beginning at the top and continuing to the bottom.
Students complete two trials using cards with differently arranged numbers. The score is based on the average time for the two series. This test Yopp, consists of 22 items and requires students to separately articulate each phoneme in the presented words.
The student receives credit only if all sounds in a word are presented correctly. One feature that differentiates this screening measure from others is that students receive feedback after each response.
If the child's response is correct, the test administrator says, "That's right. Moreover, if the student gives an incorrect response, the examiner writes the error. Recording the errors helps the teacher decide what remediation the student requires. The student's score is the number of items correctly segmented into individual phonemes.
The test is administered individually and requires about 5 to 10 minutes per child. The Bruce test assesses phoneme deletion, a more difficult and compound skill than segmenting Yopp, The examiner asks students to delete one phoneme from the beginning, middle, or end of a word and to say the word that remains.
The positions of deleted phonemes are randomly ordered throughout the test. The test is individually administered and requires 10 minutes to administer. The teacher asks the student to delete a syllable or phoneme and say the word that is left. The measure is administered individually. The measure has 18 alternate forms and consists of randomly selected upper- and lowercase letters presented on one page.
The measure is given individually, and students have 1 minute to name as many letters as possible in the order that they appear on the page. The measure has 18 alternate forms. Each form consists of 10 words, each with two or three phonemes, randomly selected from words in the pre-primer and primer levels of the Scribner basal reading series. The measure is administered individually and is timed.
Unlike the Yopp-Singer Test, students do not receive feedback on their responses but do receive scores for partially correct answers. Because this measure assesses the number of correct phonemes per minute, it is sensitive to growth and is, therefore, appropriate for both screening and monitoring progress.
As we noted at the outset of this article, efforts to understand the role of phonological awareness have far exceeded the efforts to relate research findings to classroom practice regarding phonological awareness. This article is an attempt to pull together the valuable information available on the role that phonological awareness plays in early reading development, the research-based teaching strategies that address the needs of all children, the instructional design principles that address the needs of children experiencing delays in early reading development, and the validated instruments available for screening and monitoring students' progress in phonological awareness.
Our description of the role that phonological awareness plays in reading development conspicuously fails to address the connection of phonological awareness and spelling. This failure is not an oversight, nor should it be perceived as a statement of our beliefs regarding the importance of spelling. We firmly believe that findings from spelling research e. Recent research on phonological awareness and phonemic awareness, including how to teach and assess them, has made an extremely valuable contribution to our understanding of how to teach reading to children with learning disabilities or delays in early reading.
It is not, however, a cure for reading disabilities, but a significant advance in preventing and correcting reading difficulties so that more children are prepared to learn how to read in our alphabetic writing system. His current interests include research in professional developmental in early reading and analysis of children's discourse in mathematics classrooms.
Her interests are in research on phonological awareness and reading instruction and collaboration models in special education. Chard, University of Texas at Austin, Dept.

This is a revision of a previous submission in which we didn't use the correct basis functions; the method name changed from 'LLR-4x' to 'LRR-4x' more details LRR-4x yes yes yes yes no no no no no no no no The model used for this submission is based on VGG and it was trained using both coarse and fine annotations.
Our source code is available at: To avoid confusions with a recently appeared and similarly named approach, the submission name was updated. The name was changed for consistency with the other submission of the same work. Unlike the conventional model cascade MC that is composed of multiple independent models, LC treats a single deep model as a cascade of several sub-models.
Earlier sub-models are trained to handle easy and confident regions, and they progressively feed-forward harder regions to the next sub-model for processing. Convolutions are only calculated on these regions to reduce computations. The proposed method possesses several advantages. First, LC classifies most of the easy regions in the shallow stage and makes deeper stage focuses on a few hard regions.
Such an adaptive and 'difficulty-aware' learning improves segmentation performance. Second, LC accelerates both training and testing of deep network thanks to early decisions in the shallow stage. Third, in comparison to MC, LC is an end-to-end trainable framework, allowing joint learning of all sub-models.
One stream carries information at the full image resolution, enabling precise adherence to segment boundaries. The other stream undergoes a sequence of pooling operations to obtain robust features for recognition. Publication is under review. First, we implement dense upsampling convolution DUC to generate pixel-level prediction, which is able to capture and decode more detailed information that is generally missing in bilinear upsampling.
Second, we propose a hybrid dilated convolution HDC framework in the encoding phase. This framework 1 effectively enlarges the receptive fields of the network to aggregate global information; 2 alleviates what we call the "gridding issue" caused by the standard dilated convolution operation.
We evaluate our approaches thoroughly on the Cityscapes dataset, and achieve a new state-of-art result of Pretrained models are available at https: Using only the training set without extra coarse annotated data only images. No post-processing like CRF. To our knowledge, this is the first model to employ predictive feature learning in the video scene parsing.
Besides, to enrich deep features, we use different features from multiple levels, and adopt a novel attention model to fuse them. We used only the training set without extra coarse annotated data only images and no pre-training ImageNet nor pre or post-processing. To handle the problem of segmenting objects at multiple scales, we employ a module, called Atrous Spatial Pyrmid Pooling ASPP , which adopts atrous convolution in parallel to capture multi-scale context with multiple atrous rates.
Furthermore, we propose to augment ASPP module with image-level features encoding global context and further boost performance. More details will be shown in the updated arXiv report. Close objects cover significantly more pixels than far objects. In this paper, we address this challenge with a scale invariant architecture. Within this architecture, we explicitly estimate the depth and adapt the pooling field size accordingly.
Our model is compact and can be extended easily to other research domains. Finally, the accuracy of our approach is comparable to the state-of-the-art and superior for scale problems. We evaluate on the widely used automotive dataset Cityscapes as well as a self-recorded dataset. In this paper we make the observation that the performance of such systems is strongly dependent on the relative weighting between each task's loss.
Tuning these weights by hand is a difficult and expensive process, making multi-task learning prohibitive in practice. We propose a principled approach to multi-task deep learning which weighs multiple loss functions by considering the homoscedastic uncertainty of each task. This allows us to simultaneously learn various quantities with different units or scales in both classification and regression settings. We demonstrate our model learning per-pixel depth regression, semantic and instance segmentation from a monocular input image.
Perhaps surprisingly, we show our model can learn multi-task weightings and outperform separate models trained individually on each task. Smooth Network and Border Network. Specifically, to handle the intra-class inconsistency problem, we specially design a Smooth Network with Channel Attention Block and global average pooling to select the more discriminative features.
Furthermore, we propose a Border Network to make the bilateral features of boundary distinguishable with deep semantic boundary supervision. Based on our proposed DFN, we achieve state-of-the-art performance Recent approaches have attempted to harness the capabilities of deep learning. However, one central problem of these methods is that deep convolution neural network gives little consideration to the correlation among pixels.
To handle this issue, in this paper, we propose a novel deep neural network named RelationNet, which utilizes CNN and RNN to aggregate context information. Besides, a spatial correlation loss is applied to supervise RelationNet to align features of spatial pixels belonging to same category.
Importantly, since it is expensive to obtain pixel-wise annotations, we exploit a new training method for combining the coarsely and finely labeled data. Separate experiments show the detailed improvements of each proposal. Experimental results demonstrate the effectiveness of our proposed method to the problem of semantic image segmentation.
In-Place Activated BatchNorm yes yes yes yes no no no no no no no no Test results are obtained using a single model. ESPNet is based on a new convolutional module, efficient spatial pyramid ESP , which is efficient in terms of computation, memory, and power. Under the same constraints on memory and computation, ESPNet outperforms all the current efficient CNN networks such as MobileNet, ShuffleNet, and ENet on both standard metrics and our newly introduced performance metrics that measure efficiency on edge devices.
A tractable surrogate for the optimization of the intersection-over-union measure in neural networks Maxim Berman, Amal Rannen Triki, Matthew B. Here we finetune the weights provided by the authors of ENet arXiv: The runtimes are unchanged with respect to the ENet architecture.
Global context plays an important role on local pixel-wise category assignment. To make the best of global context, in this paper, we propose dense relation network DRN and context-restricted loss CRL to aggregate global and local information. Compared with previous methods, our proposed method takes full advantage of hierarchical contextual representations to produce high-quality results. Extensive experiments demonstrate that our methods achieves significant state-of-the-art performances on Cityscapes and Pascal Context benchmarks, with mean-IoU of An efficient realtime semantic segmentation network with skip connections and ShuffleNet units more details SkipNet-MobileNet yes yes yes yes no no no no no no no no The former networks are able to encode multi-scale contextual information by probing the incoming features with filters or pooling operations at multiple rates and multiple effective fields-of-view, while the latter networks can capture sharper object boundaries by gradually recovering the spatial information.
In this work, we propose to combine the advantages from both methods. We further explore the Xception model and apply the depthwise separable convolution to both Atrous Spatial Pyramid Pooling and decoder modules, resulting in a faster and stronger encoder-decoder network.
We will provide more details in the coming update on the arXiv report. To tackle this issue, we firstly propose a novel Kronecker convolution which adopts Kronecker product to expand its kernel for taking into account the feature vectors neglected by atrous convolutions.
Therefore, it can capture local contextual information and enlarge the field of view of filters simultaneously without introducing extra parameters.
Secondly, we propose Tree-structured Feature Aggregation TFA module which follows a recursive rule to expand and forms a hierarchical structure.
Thus, it can naturally learn representations of multi-scale objects and encode hierarchical contextual information in complex scenes. State-of-the-art methods are, however, not directly transferable to real-time applications or embedded devices, since naive adaptation of such systems to reduce computational cost speed, memory and energy causes a significant drop in accuracy.
We propose ContextNet, a new deep neural network architecture which builds on factorized convolution, network compression and pyramid representations to produce competitive semantic segmentation in real-time with low memory requirements.
