Collaborative or distributed or federated learning focuses on a joined optimization of a model, with maximum accuracy  (or minimal error) in mind. Compare this post here. The answer depends on statistics and the distribution of the value instances. If for example the given … Continue reading →

I ask myself what are the mayor differences between the todays AD stacks such as NVIDIA Drive (OS, Sim, Works) or BAIDU Apollo (Auto) and the Software Defined Vehicle (SDV) operating system (OS) approaches. OS & middleware components In a … Continue reading →

Peripheral Component Interconnect Express (PCIe) is a serial (data is sent in series i.e. one after the other), point-to-point (from device to device), wired (silicon based), individually clocked (time synchronized between devices), lane based (see below), upstream and downstream simultaneously (full-duplex) interconnection. … Continue reading →

Data science is one of the magic disciplines in this century. It is all about deriving insights from data. Data can be observed everywhere, but for insights, the observation needs to be  explored or  well-understood descriptions e.g. equations.   Exploration is … Continue reading →

First of all we are talking about “actuation”. A system is openly (open loop) controlled is the feedback of the actuation is not played back. Otherwise, if the (feedback) sensing is included, we call it closed loop. A common mechanism … Continue reading →

Two criteria…. Code isolation: Separate packages: no Separate build modules: no Separate repositories: no Separate runtimes: yes 2. Data isolation: Separate table: no Separate schema: no Separate databases: yes

Vehicle software architecture evolves from “central gateway” approaches, where each function has its own processor (ECU) interconnected through gateways, to “domain centered” approaches beginning in 2025. Domain centricity logically group or merge multiple ECUs by requirements similarity. Domains may also … Continue reading →
