Distributed computing and data analysis technology in Java
With the advent of the big data era, the explosive growth of data volume has brought huge impact to traditional computing methods. In order to solve this problem, distributed computing and data analysis technology emerged. As a general-purpose programming language, Java has shown good performance in the fields of distributed computing and data analysis.
1. Distributed Computing Technology
Distributed computing is a technology that divides computing tasks into several sub-tasks. Each sub-task can be run on different computers, and then their output The results are merged into the final result. This technology can significantly improve computing efficiency and improve system scalability.
In distributed computing technology, the most commonly used tools for Java are Hadoop and Spark. Hadoop is a Java-based big data distributed processing framework that can process large amounts of data in a distributed manner and can store and process data across multiple computer nodes. Spark is another Java-based framework that provides a fast, general-purpose engine for processing large-scale data sets that can run on a Hadoop cluster.
2. Data analysis technology
Data analysis refers to the use of various technologies and tools to process and analyze massive data to discover the patterns and trends hidden behind the data. Java also has many excellent tools and frameworks for data analysis.
- Mahout
Mahout is a Java-based machine learning platform that can be used for data mining and data analysis of large-scale data sets. It provides many machine learning algorithms, including clustering, classification, etc.
- Weka
Weka is a Java-based open source machine learning tool that can be used for data mining, predictive modeling, cluster analysis, etc. It provides many data preprocessing and machine learning algorithms.
- ELK
ELK is a universal log data analysis solution, consisting of three smooth collaboration tools: Logstash, Elasticsearch and Kibana. Logstash is a log data collector, Elasticsearch is a distributed search and analysis engine, and Kibana is a user-friendly web front-end that can be used to count and analyze log data in real time.
3. Conclusion
Java has shown good performance and scalability in the fields of distributed computing and data analysis. Various open source tools and frameworks help Java developers process and analyze large-scale data sets faster. During the application design and implementation process, developers should choose appropriate distributed computing and data analysis tools and frameworks based on specific needs to ensure performance and scalability.

This article is enough for you to read about autonomous driving and trajectory prediction!
Feb 28, 2024 pm 07:20 PM
Trajectory prediction plays an important role in autonomous driving. Autonomous driving trajectory prediction refers to predicting the future driving trajectory of the vehicle by analyzing various data during the vehicle's driving process. As the core module of autonomous driving, the quality of trajectory prediction is crucial to downstream planning control. The trajectory prediction task has a rich technology stack and requires familiarity with autonomous driving dynamic/static perception, high-precision maps, lane lines, neural network architecture (CNN&GNN&Transformer) skills, etc. It is very difficult to get started! Many fans hope to get started with trajectory prediction as soon as possible and avoid pitfalls. Today I will take stock of some common problems and introductory learning methods for trajectory prediction! Introductory related knowledge 1. Are the preview papers in order?

The Stable Diffusion 3 paper is finally released, and the architectural details are revealed. Will it help to reproduce Sora?
Mar 06, 2024 pm 05:34 PM
StableDiffusion3’s paper is finally here! This model was released two weeks ago and uses the same DiT (DiffusionTransformer) architecture as Sora. It caused quite a stir once it was released. Compared with the previous version, the quality of the images generated by StableDiffusion3 has been significantly improved. It now supports multi-theme prompts, and the text writing effect has also been improved, and garbled characters no longer appear. StabilityAI pointed out that StableDiffusion3 is a series of models with parameter sizes ranging from 800M to 8B. This parameter range means that the model can be run directly on many portable devices, significantly reducing the use of AI
DualBEV: significantly surpassing BEVFormer and BEVDet4D, open the book!
Mar 21, 2024 pm 05:21 PM
This paper explores the problem of accurately detecting objects from different viewing angles (such as perspective and bird's-eye view) in autonomous driving, especially how to effectively transform features from perspective (PV) to bird's-eye view (BEV) space. Transformation is implemented via the Visual Transformation (VT) module. Existing methods are broadly divided into two strategies: 2D to 3D and 3D to 2D conversion. 2D-to-3D methods improve dense 2D features by predicting depth probabilities, but the inherent uncertainty of depth predictions, especially in distant regions, may introduce inaccuracies. While 3D to 2D methods usually use 3D queries to sample 2D features and learn the attention weights of the correspondence between 3D and 2D features through a Transformer, which increases the computational and deployment time.
More than just 3D Gaussian! Latest overview of state-of-the-art 3D reconstruction techniques
Jun 02, 2024 pm 06:57 PM
Written above & The author’s personal understanding is that image-based 3D reconstruction is a challenging task that involves inferring the 3D shape of an object or scene from a set of input images. Learning-based methods have attracted attention for their ability to directly estimate 3D shapes. This review paper focuses on state-of-the-art 3D reconstruction techniques, including generating novel, unseen views. An overview of recent developments in Gaussian splash methods is provided, including input types, model structures, output representations, and training strategies. Unresolved challenges and future directions are also discussed. Given the rapid progress in this field and the numerous opportunities to enhance 3D reconstruction methods, a thorough examination of the algorithm seems crucial. Therefore, this study provides a comprehensive overview of recent advances in Gaussian scattering. (Swipe your thumb up
Revolutionary GPT-4o: Reshaping the human-computer interaction experience
Jun 07, 2024 pm 09:02 PM
The GPT-4o model released by OpenAI is undoubtedly a huge breakthrough, especially in its ability to process multiple input media (text, audio, images) and generate corresponding output. This ability makes human-computer interaction more natural and intuitive, greatly improving the practicality and usability of AI. Several key highlights of GPT-4o include: high scalability, multimedia input and output, further improvements in natural language understanding capabilities, etc. 1. Cross-media input/output: GPT-4o+ can accept any combination of text, audio, and images as input and directly generate output from these media. This breaks the limitation of traditional AI models that only process a single input type, making human-computer interaction more flexible and diverse. This innovation helps power smart assistants
Review! Deep model fusion (LLM/basic model/federated learning/fine-tuning, etc.)
Apr 18, 2024 pm 09:43 PM
In September 23, the paper "DeepModelFusion:ASurvey" was published by the National University of Defense Technology, JD.com and Beijing Institute of Technology. Deep model fusion/merging is an emerging technology that combines the parameters or predictions of multiple deep learning models into a single model. It combines the capabilities of different models to compensate for the biases and errors of individual models for better performance. Deep model fusion on large-scale deep learning models (such as LLM and basic models) faces some challenges, including high computational cost, high-dimensional parameter space, interference between different heterogeneous models, etc. This article divides existing deep model fusion methods into four categories: (1) "Pattern connection", which connects solutions in the weight space through a loss-reducing path to obtain a better initial model fusion
