This document discusses building an image classification model using Amazon SageMaker and deploying it via an API Gateway and Lambda function. Key steps include:
1. Developing a Python Lambda function to preprocess images from API requests and call a SageMaker endpoint for predictions.
2. Creating an IAM role for the Lambda function to access SageMaker.
3. Building and deploying the SageMaker model.
4. Configuring API Gateway to invoke the Lambda function via a REST API, with the Lambda function returning classification results.
This allows building and deploying a machine learning model on SageMaker and serving predictions through a serverless API for image classification.
The document discusses graph databases and their properties. Graph databases are structured to store graph-based data by using nodes and edges to represent entities and their relationships. They are well-suited for applications with complex relationships between entities that can be modeled as graphs, such as social networks. Key graph database technologies mentioned include Neo4j, OrientDB, and TinkerPop which provides graph traversal capabilities.

Fighting advanced malware using machine learning (Japanese)FFRI, Inc.
n this paper, behavioral-based detection powered by machine learning is introduced. As the result, detection ratio is dramatically improved by comparison with traditional detection.
Needless to say that malware detection is getting harder today. Everybody knows signature-based detection reaches its limit, so that most anti-virus vendors use heuristic, behavioral and reputation-based detections altogether. About targeted attack, basically attackers use undetectable malware, so that reputation-based detection doesn't work well because it needs other victims beforehand. And it is a fact that detection ratio is not enough though we use heuristic and behavioral-based detections. In our research using the Metascan, average detection ratio of newest malware by most anti-virus scanner is about 30 %( the best is about 60 %).
By the way, heuristic and behavioral-based detections are developed by knowledge and experience of malware analyst. For example, most analysts know that following features are indicator that those programs are malicious.
- A file imports VirtualAlloc, VirtualProtect and LoadLibrary only and has a strange section name
- An entry point that does not fall within declared text or code section
- Creating remote threads into a legitimate process like explore.exe
- After unpacking, calling OpenMutex and CreateMutex to avoid multiple infections
- Register itself to auto start extension points like services and registry
- Creating a .bat file and try to delete own itself through executing the file with cmd.exe
- Setting global hook to capture keystroke using SetWindowsHookEx
Heuristic and behavioral-based detections are developed based on those pre-determined features like above. Analysts are finding those features day by day. But, this kind of work is not appropriate for human. Therefore we classified programs as malware or benign by machine learning through dynamic analysis results. Thereby, detection ratio is dramatically improved and we could recognize that which features are strongly related to malware by numeric score. And then, we could find the features which we’ve never found by this method. Finally, the outlook and challenges of this method will be tackled.
The document discusses custom management applications developed for Apache Kafka. It describes applications called KafkaTopicManageApp and KafkaAclManageApp that use the Apache Kafka AdminClient to manage topics and ACLs in an idempotent way based on application and target configuration files. This allows operations to be reviewed and applied automatically through continuous integration to keep the Kafka cluster configuration in sync with the defined settings.
Stream processing is designed for continuously processing unbounded data streams. It allows for unbounded data inputs and continuous processing, unlike batch processing which requires bounded, finite data sets. The key challenges of stream processing include out-of-order data arrival and needing to relate events that occur close together in time but may be processed out of order. To address this, stream processing systems use watermarks to indicate processing progress, triggers to determine output timing, and accumulation to handle refinements from late data.
