Xelera Silva

Gradient Boosting frameworks such as XGBoost, LightGBM and CatBoost, as well as Random Forest algorithms are widely used in ransomware and DDOS detection systems, recommender systems and trading systems. Xelera Silva a Decision Tree acceleration software provides best-in-class throughput and latency for XGBoost, LightGBM and Random Forest inference by leveraging COTS datacenter-grade FPGA accelerators.

Application areas

Network Threat Detection

The network is the first instance that must be protected in order to secure the enterprise IT system. Machine learning-powered firewalls perform application-level inspection to detect suspicious patterns in the network flow data (e.g. in the case of a DDOS attack). Silva provides the inferencing speed required to ensure that computationally demanding machine learning-based firewalls can operate at an adequate speed to avoid a slowing-down of the IT system.

Ransomware Detection

Ransomware cyber attacks are rising at a rapid pace and traditional security approaches often fail to intercept them. Gradient Boosting Decision Tree and Random Forest algorithms are among the most widely used techniques for the automated detection of ransomware attacks. A high filtering throughput and low detection latency are the key objectives in these systems. Silva satisfies these performance constraints by ensuring a high throughput at an ultra-low latency.

Risk Management

The value at risk assessment and the credit risk assessment of contract counterparties are two statistical techniques to manage the risk in financial transactions. Both techniques shift more and more frequently towards real-time processes. On the other hand, both techniques often rely on data- and compute-intensive Monte Carlo methods. Xelera Analytics makes these methods real-time capable.

Algorithmic Trading

Algorithmic trading usually relies on time series analyses using Markov-like model such as autoregressive or moving average models, while Deep Learning-based techniques are under investigation. The more complex these models are, the more compute delay they cause. Xelera Analytics help keep this compute delay at a minimum, which is particularly important in high- frequency trading.
