**CodeGen** is an autoregressive transformers with next-token prediction language modeling as the learning objective trained on a natural language corpus and programming language data curated from GitHub.

**Cross-Covariance Image Transformers**, or **XCiT**, is a type of [vision transformer](https://paperswithcode.com/methods/category/vision-transformer) that aims to combine the accuracy of [conventional transformers](https://paperswithcode.com/methods/category/transformers) with the scalability of [convolutional architectures](https://paperswithcode.com/methods/category/convolutional-neural-networks). 

The [self-attention operation](https://paperswithcode.com/method/scaled) underlying transformers yields global interactions between all tokens, i.e. words or image patches, and enables flexible modelling of image data beyond the local interactions of convolutions. This flexibility, however, comes with a quadratic complexity in time and memory, hindering application to long sequences and high-resolution images. The authors propose a “transposed” version of self-attention called [cross-covariance attention](https://paperswithcode.com/method/cross-covariance-attention) that operates across feature channels rather than tokens, where the interactions are based on the cross-covariances matrix between keys and queries.

CodeGen: An Open Large Language Model for Code with Multi-Turn Program Synthesis

The monocular depth estimation (MDE) is the task of estimating depth from a single frame. This information is an essential knowledge in many computer vision tasks such as scene understanding and visual odometry, which are key components in autonomous and robotic systems. 
Approaches based on the state of the art vision transformer architectures are extremely deep and complex not suitable for real-time inference operations on edge and autonomous systems equipped with low resources (i.e. robot indoor navigation and surveillance). This paper presents SPEED, a Separable Pyramidal pooling EncodEr-Decoder architecture designed to achieve real-time frequency performances on multiple hardware platforms. The proposed model is a fast-throughput deep architecture for MDE able to obtain depth estimations with high accuracy from low resolution images using minimum hardware resources (i.e. edge devices). Our encoder-decoder model exploits two depthwise separable pyramidal pooling layers, which allow to increase the inference frequency while reducing the overall computational complexity. The proposed method performs better than other fast-throughput architectures in terms of both accuracy and frame rates, achieving real-time performances over cloud CPU, TPU and the NVIDIA Jetson TX1 on two indoor benchmarks: the NYU Depth v2 and the DIML Kinect v2 datasets.
