• Abstract summary: Fog environment made its limited resource available to a large number of users to deploy their serverless applications. Recent research mainly focuses on assigning maximum resources to such applications from the fog node and not taking full advantage of the cloud environment. We propose DeF-DReL, a Systematic Deployment of Serverless Functions in Fog and Cloud environments using Deep Reinforcement Learning.

• Abstract: Fog computing is introduced by shifting cloud resources towards the users' proximity to mitigate the limitations possessed by cloud computing. Fog environment made its limited resource available to a large number of users to deploy their serverless applications, composed of several serverless functions. One of the primary intentions behind introducing the fog environment is to fulfil the demand of latency and location-sensitive serverless applications through its limited resources. The recent research mainly focuses on assigning maximum resources to such applications from the fog node and not taking full advantage of the cloud environment. This introduces a negative impact in providing the resources to a maximum number of connected users. To address this issue, in this paper, we investigated the optimum percentage of a user's request that should be fulfilled by fog and cloud. As a result, we proposed DeF-DReL, a Systematic Deployment of Serverless Functions in Fog and Cloud environments using Deep Reinforcement Learning, using several real-life parameters, such as distance and latency of the users from nearby fog node, user's priority, the priority of the serverless applications and their resource demand, etc. The performance of the DeF-DReL algorithm is further compared with recent related algorithms. From the simulation and comparison results, its superiority over other algorithms and its applicability to the real-life scenario can be clearly observed.

  We propose a novel. Efficient Fine-Tuning (PEFT) method for point cloud, called Point GST. Point GST freezes the pre-trained model and introduces a trainable Point Cloud Spectral Adapter (PCSA) to finetune parameters in the spectral domain. Extensive experiments on challenging point cloud datasets demonstrate that Point GST not only outperforms its fully finetuning counterpart but also significantly reduces trainable parameters.

  Serverless computing is gaining traction due to its efficiency and ability to harness on-demand cloud resources.

We propose SPES, the first differentiated scheduler for runtime cold start mitigation by optimizing serverless function provision.

• Managing Cold-start in The Serverless Cloud with Temporal Convolutional Networks [0.0]
  Serverless cloud is an innovative cloud service model that frees customers from most cloud management duties. A big threat to the serverless cloud's performance is cold-start, which is when the time of provisioning the needed cloud resource to serve customers' requests incurs unacceptable costs to the service providers and/or the customers. This paper proposes a novel low-coupling, high-cohesion ensemble policy that addresses the cold-start problem at infrastructure- and function-levels of the serverless cloud stack.
