Self-Supervised Learning with Vision Transformers

Self-Supervised Learning with Vision Transformers By Zhenda Xie*, Yutong Lin*, Zhuliang Yao, Zheng Zhang, Qi Dai, Yue Cao and Han Hu This repo is the official implementation of “Self-Supervised Learning with Swin Transformers”. A important feature of this codebase is to include Swin Transformer as one of the backbones, such that we can evaluate the transferring performance of the learnt representations on down-stream tasks of object detection and semantic segmentation. This evaluation is usually not included in previous works due […]

Using VideoBERT to tackle video prediction

VideoBERT This repo reproduces the results of VideoBERT (https://arxiv.org/pdf/1904.01766.pdf). Inspiration was taken from https://github.com/MDSKUL/MasterProject, but this repo tackles video prediction rather than captioning and masked language modeling. On a side note, since this model is extremely small, the results that are displayed here are extremely basic. Feel free to increase the model size per your computational resources and change the inference file to include temperature if necessary (As of now I have not implemented temperature). Here are all the steps […]

Vision-Language Pre-training on Fashion Domain

Kaleido-BERT: Vision-Language Pre-training on Fashion Domain Mingchen Zhuge*, Dehong Gao*, Deng-Ping Fan#, Linbo Jin, Ben Chen, Haoming Zhou, Minghui Qiu, Ling Shao. Introduction We present a new vision-language (VL) pre-training model dubbed Kaleido-BERT, which introduces a novel kaleido strategy for fashion cross-modality representations from transformers. In contrast to random masking strategy of recent VL models, we design alignment guided masking to jointly focus more on image-text semantic relations.To this end, we carry out five novel tasks, ie, rotation, jigsaw, camouflage, […]

A Benchmark for Interpreting Grounded Instructions for Everyday Tasks

ALFRED ALFRED (Action Learning From Realistic Environments and Directives), is a new benchmark for learning a mapping from natural language instructions and egocentric vision to sequences of actions for household tasks. Long composition rollouts with non-reversible state changes are among the phenomena we include to shrink the gap between research benchmarks and real-world applications. What more? Checkout ALFWorld – interactive TextWorld environments for ALFRED scenes! Quickstart Clone repo: $ git clone https://github.com/askforalfred/alfred.git alfred $ export ALFRED_ROOT=$(pwd)/alfred Install requirements: $ virtualenv […]

DeLighT: Very Deep and Light-weight Transformers

DeLighT: Very Deep and Light-weight Transformers This repository contains the source code of our work on building efficient sequence models: DeFINE (ICLR’20) and DeLighT (preprint). Overview In this repository, we share the source code of our paper DeLight, that delivers similar or better performance thantransformer-based models with significantly fewer parameters. DeLighT more efficiently allocates parameters both (1)within each Transformer block using DExTra, a deep and light-weight transformation and (2) across blocks usingblock-wise scaling, that allows for shallower and narrower DeLighT […]
