Software systems often record important runtime information in system logs for troubleshooting purposes. There have been many studies that use log data to construct machine learning models for detecting system anomalies. Through our empirical study, we find that existing log-based anomaly detection approaches are significantly affected by log parsing errors that are introduced by 1) OOV (out-of-vocabulary) words, and 2) semantic misunderstandings. The log parsing errors could cause the loss of important information for anomaly detection. To address the limitations of existing methods, we propose NeuralLog, a novel log-based anomaly detection approach that does not require log parsing. NeuralLog extracts the semantic meaning of raw log messages and represents them as semantic vectors. These representation vectors are then used to detect anomalies through a Transformer-based classification model, which can capture the contextual information from log sequences. Our experimental results show that the proposed approach can effectively understand the semantic meaning of log messages and achieve accurate anomaly detection results. Overall, NeuralLog achieves F1-scores greater than 0.95 on four public datasets, outperforming the existing approaches.

What I have learnt will be focusing on Deep L-layer neural network. Deep neural network represent a network with lots of hidden layers instead of logistic regression or 2 layer NN. Some problem can be tackled easily by using a shallow neural network or logistic regression. It was suggested that we can start for a problem by using logistic regression or shallow neural network. Then, we can try to tune the number of hidden layer or some hyper-parameter to figure the most suitable deep neural network.

DeepMind has created a virtual playground that shows a path to creating general AI -- the holy grail of artificial intelligence. Reinforcement learning: If you want to train an AI to play chess, you can set up a virtual chessboard, list the rules, and let the AI learn the game through trial and error. When it does something "right," such as capturing a pawn, you give it a reward. When it does something majorly right, like winning the game, you give it a bigger reward. Eventually, the AI will learn what it needs to do to get the most rewards, and boom, you have an AI that can beat any human at chess.

The AI world changed March 15 2016 when DeepMind's AlphaGo reinforcement machine learning model beat Lee Sedol, a world champion at Go, demonstrating that computers have officially surpassed humans in gaming situations when looking to make the best decision/move based on an infinite number of possibilities.

Ever since DeepMind published its work on the application of Deep Reinforcement Learning on playing Atari games, the attraction to this subdomain of AI has increased by many manifolds. RL is truly a giant step forward towards achieving general intelligence for autonomous agents and promises to revolutionise the way the world works. But even though this field has caught up the attention of many people with hundreds of researchers making contributions to it, it's still in a rudimentary stage which is ever evolving. For a fresher it can be quite a daunting task about how to get started with RL with numerous resources available. I was in the same boat a year before.

Natural language processing continues to find its way into unexpected corners. In a small study, researchers found that they could use the deep learning language model GPT-3, along with other AI-as-a-service platforms, to significantly lower the barrier to entry for crafting spearphishing campaigns at a massive scale. Researchers have long debated whether it would be worth the effort for scammers to train machine learning algorithms that could then generate compelling phishing messages. Mass phishing messages are simple and formulaic, after all, and are already highly effective. Highly targeted and tailored "spearphishing" messages are more labor intensive to compose, though.

This is the 4th in a series of panel discussions in collaboration with Neuromatch Academy, the online computational neuroscience summer school. This is the first of 3 in the deep learning series. In this episode, the panelists discuss their experiences with some basics in deep learning, including Linear deep learning, Pytorch, multi-layer-perceptrons, optimization, & regularization.

The traditional production paradigm of large batch production does not offer flexibility towards satisfying the requirements of individual customers. A new generation of smart factories is expected to support new multi-variety and small-batch customized production modes. For that, Artificial Intelligence (AI) is enabling higher value-added manufacturing by accelerating the integration of manufacturing and information communication technologies, including computing, communication, and control. The characteristics of a customized smart factory are to include self-perception, operations optimization, dynamic reconfiguration, and intelligent decision-making. The AI technologies will allow manufacturing systems to perceive the environment, adapt to the external needs, and extract the process knowledge, including business models, such as intelligent production, networked collaboration, and extended service models. This paper focuses on the implementation of AI in customized manufacturing (CM). The architecture of an AI-driven customized smart factory is presented. Details of intelligent manufacturing devices, intelligent information interaction, and construction of a flexible manufacturing line are showcased. The state-of-the-art AI technologies of potential use in CM, i.e., machine learning, multi-agent systems, Internet of Things, big data, and cloud-edge computing are surveyed. The AI-enabled technologies in a customized smart factory are validated with a case study of customized packaging. The experimental results have demonstrated that the AI-assisted CM offers the possibility of higher production flexibility and efficiency. Challenges and solutions related to AI in CM are also discussed.
