ECA-Net: Efficient Channel Attention for Deep Convolutional Neural Networks

Proposes Efficient Channel Attention (ECA), a lightweight module using 1D convolution without dimensionality reduction to boost CNN accuracy cheaply.

Channel attention improves deep CNNs, but most modules add substantial complexity. This paper proposes Efficient Channel Attention (ECA), which uses very few parameters yet yields clear gains. Analyzing SENet, the authors show avoiding dimensionality reduction matters and that local cross-channel interaction preserves performance while cutting complexity; it is implemented via 1D convolution with an adaptively chosen kernel size. On ResNets and MobileNetV2, ECA improves classification, detection and segmentation with negligible overhead.

Seaborn: Statistical Data Visualization

Presents seaborn, a Python library offering a high-level, dataset-oriented interface to matplotlib for statistical data visualization.

Seaborn is a Python library for statistical graphics, offering a high-level interface to matplotlib and integrating with pandas data structures. Its declarative, dataset-oriented API lets users translate questions about data into graphics: given a dataset and plot specification, seaborn maps data values to visual attributes like color, size, and style, computes statistical transformations internally, and adds informative labels and legends. It also produces multi-panel figures for comparisons, supporting rapid exploratory analysis and polished, publication-quality output.

Dense Passage Retrieval for Open-Domain Question Answering

Introduces Dense Passage Retrieval, a dual-encoder that learns dense embeddings to outperform BM25 for open-domain question answering passage retrieval.

Open-domain question answering depends on efficient passage retrieval, traditionally handled by sparse models like TF-IDF or BM25. This work shows retrieval can be done using dense representations alone, with embeddings learned from a small number of question-passage pairs via a simple dual-encoder framework. Across several open-domain QA datasets, the dense retriever beats a strong Lucene-BM25 system by 9-19% absolute in top-20 retrieval accuracy, and helps the end-to-end QA system set new state-of-the-art results on multiple benchmarks.

YOLOX: Exceeding YOLO Series in 2021

Introduces YOLOX, an anchor-free YOLO detector with a decoupled head and SimOTA label assignment achieving state-of-the-art speed-accuracy.

YOLOX upgrades the YOLO object-detection series by switching to an anchor-free design and adding a decoupled head and the SimOTA label assignment strategy. These changes yield state-of-the-art results across model sizes: YOLO-Nano reaches 25.3% AP on COCO, YOLOv3 is boosted to 47.3% AP, and YOLOX-L attains 50.0% AP at 68.9 FPS on a Tesla V100, exceeding YOLOv5-L by 1.8% AP. A single YOLOX-L model won first place in the CVPR 2021 Streaming Perception Challenge, and deploy versions support ONNX, TensorRT, NCNN, and OpenVINO.

Large Scale GAN Training for High Fidelity Natural Image Synthesis

Trains GANs (BigGAN) at the largest scale yet, using a truncation trick to set new state of the art in class-conditional ImageNet image synthesis.

Generating high-resolution, diverse samples from complex datasets like ImageNet remains difficult. The authors train GANs at the largest scale yet attempted and study the resulting instabilities. Applying orthogonal regularization to the generator enables a 'truncation trick' that trades off sample fidelity against variety by shrinking input variance. These BigGAN models set a new state of the art in class-conditional synthesis, reaching an Inception Score of 166.5 and FID of 7.4 at 128x128 on ImageNet, up from 52.52 IS and 18.6 FID.

Neural Architecture Search with Reinforcement Learning

Uses an RNN trained with reinforcement learning to automatically generate neural network architectures that rival human-designed models.

This paper uses a recurrent network to generate neural network descriptions and trains this RNN with reinforcement learning to maximize the expected validation accuracy of generated architectures. On CIFAR-10, the method designs a novel architecture from scratch that rivals the best human-invented designs, achieving a 3.65% test error—0.09% better and 1.05x faster than a comparable prior model. On Penn Treebank, it composes a new recurrent cell that beats the LSTM, reaching 62.4 perplexity, and transfers to character language modeling with 1.214 perplexity.

Empirical Analysis of Predictive Algorithms for Collaborative Filtering

Describes and compares collaborative filtering algorithms—correlation, vector similarity, and Bayesian methods—for recommender prediction.

This paper describes and compares several collaborative filtering algorithms for predicting items a user might like, including correlation coefficients, vector-based similarity, and Bayesian methods. Accuracy is measured with two metric classes: average absolute deviation over individual predictions, and the utility of a ranked recommendation list. Across three domains, four protocols, and both metrics, Bayesian networks with decision-tree nodes and correlation methods outperform Bayesian clustering and vector similarity; the best depends on the dataset and application.

Generalized Intersection Over Union: A Metric and a Loss for Bounding Box Regression

Introduces Generalized IoU (GIoU), a metric and loss for bounding box regression that handles non-overlapping boxes and improves object detectors.

Intersection over Union (IoU) is the standard object-detection metric, yet common distance-based losses for regressing bounding boxes do not directly optimize it. IoU can act as a regression loss for axis-aligned 2D boxes, but its plateau makes optimization infeasible for non-overlapping boxes. The authors introduce Generalized IoU (GIoU) as both a new metric and a new loss that fixes this weakness. Adding GIoU as a loss to state-of-the-art detectors yields consistent improvements on PASCAL VOC and MS COCO under both IoU- and GIoU-based measures.

The Power of Scale for Parameter-Efficient Prompt Tuning

Introduces prompt tuning, learning soft prompts via backpropagation to adapt frozen language models, matching full model tuning as scale grows.

The paper explores prompt tuning, a mechanism for learning soft prompts that condition frozen language models for downstream tasks. Unlike GPT-3's discrete text prompts, soft prompts are learned via backpropagation from labeled examples and outperform GPT-3's few-shot learning by a large margin. Ablations with T5 show the method grows more competitive with scale, matching full model tuning once models exceed billions of parameters. Soft prompts also improve robustness to domain transfer and enable efficient prompt ensembling.
