About this project
What does Extra Hostile Neural Networks add?
Extra Hostile Neural Networks
This mod is an addon to the Hostile Neural Networks mod
The mod adds 4 mechanisms and a new data model.
Merger Camera

Adds the ability to combine 4 Data Modes equal to the Self Aware tier into a perfect Data Mode that combines all 4 of those models into one.
Ultimate Simulation Chamber

Works like a regular mechanism, except that only Extra Data Model can be placed here. It will create predictions of all types that are in the model at once. It is also slightly accelerated compared to its analogues
Processes x4, x16, x32 and x64 at a time, respectively
Ultimate Loot Fabricator

A more advanced version of Loot Fabricator from Hostile Neural Networks. Allows processing up to 4 predictions simultaneously.
Processes x4, x16, x32 and x64 at a time, respectively
Simulator Modeling

Allows you to quickly train models to the maximum level, consuming a large amount of energy. Does not produce loot during simulation. Supports 2 upgrades.
Also added 3 improvements for Simulator Modeling

- Increase speed by 50%, but energy consumption increases by 2 times
- Allows you to instantly upgrade to the next model tier, but energy consumption increases to 10M FE/T
Increases the amount of data received per simulation by 2 times
The parameters of the improvements can be configured in the config
The new data model cannot be encoded in any way like the regular one. It can only be obtained through the Merger Camera.
