Invariant Causal Imitation Learning for Generalizable Policies

Ioana Bica, Daniel Jarrett, Mihaela van der Schaar Neural Information Processing Systems (NeurIPS) 2021 Dependencies The code was implemented in Python 3.6 and the following packages are needed for running it: gym==0.17.2 numpy==1.18.2 pandas==1.0.4 tensorflow==1.15.0 torch==1.6.0 tqdm==4.32.1 scipy==1.1.0 scikit-learn==0.22.2 stable-baselines==2.10.1 Running and evaluating the model: The control tasks used for experiments are from OpenAI gym [1]. Each control task is associated with a true rewardfunction (unknown to the imitation algorithm). In each case, the “expert” demonstrator can be obtained by […]

A simple video player written in python using ffpyplayer and OpenCV

cvplayer is a minimal wrapper around the ffpyplayer.MediaPlayer class for playing videos through interactive (direct access to the player through keymaps) or scripts (getting a VideoPlayer instance and doing whatever the user wants to) audio playback and supplying frames is handles by ffpyplayer and OpenCV is used to display the frames this makes it useful for simple interactable video playback as well for integrating video playback in programs Scripted access cvplayer provides the VideoPlayer class which is the main wrapper […]

Details,PoC and patches for CVE-2021-45383 & CVE-2021-45384

There are several network-layer vulnerabilities in the official server of Minecraft: Bedrock Edition (aka Bedrock Server),which allow attacker to launch a DoS attack.CVE-2021-45383 is an integer overflow leading to a bound check bypass.CVE-2021-45384 is a null pointer dereference.Here are details & PoCs & possible patches for them. Because both vulnerabilities lie in the network protocol handler,attackers can launch a DoS attack without logining or being in the server player allowlist.CVE-2021-45383 affects Bedrock Server 1.16.0-1.18.2.03.CVE-2021-45384 is an old vulnerability and affects […]
