What is Hostile Neural Networks?
1 part
Same as in the FTB Skies 2: Aero 1.10.0 guide
Hostile Neural Networks lets you simulate mobs and turn the simulations into their drops. You build a Data Model of a mob, train it, run simulations, and feed the resulting predictions into a machine that spits out loot. The pack includes version 6.5.1 of the mod.[1][2]
Here is the flow. You craft a Model Framework and use it on the target mob to build its Data Model. Models start out Faulty and must be trained up to Basic in a Deep Learner. Once a model is Basic or higher, you run it in the Simulation Chamber, which needs energy and a catalyst, usually a Prediction Matrix. Accuracy rises with the model tier, up to 99.5% at Self Aware. Finally, the Loot Fabricator uses power to convert mob predictions into drops.[1]
Where it sits in the quest book
The pack's quest book covers this mod in the "Generating Resources" chapter. That chapter is in the "Resources & Logistics" group and is chapter 8 of 31 in the book. It has 99 quests and sits alongside other resource farming topics such as Mystical Agriculture, Productive Bees and Spawner Farms.[3]
The mod's quests form one chain inside that chapter:[3]
- "Hostile Neural Networks!" quest is the starting quest. It asks for the Model Framework and the Deep Learner, and tells you to level the model to at least Basic.[3]
- a quest in "Generating Resources" comes after it. It covers the Simulation Chamber and Prediction Matrices, including its Training Mode and Inference Mode. The book has no title of its own for this quest, so it is named after the item it asks for.[3]
- a quest in "Generating Resources" comes after that. It explains choosing a drop in the Loot Fabricator and its Queue Mode. This quest is also untitled in the book.[3]
- "Neural Data Center" quest comes after the Loot Fabricator quest. It describes the Data Center multiblock, a 7x7x7 structure that runs up to 25 Self Aware data models at the same time, with Data Center IO Port blocks for energy, inputs and outputs.[3]
The text of 82 of the chapter's 99 quests is in the quest book itself, so check there for anything beyond this chain.[3]
Unverified Whether the ATM Star path uses this mod is not shown by the sources here. Check the pack's quest book for that.
How do you get started with Hostile Neural Networks?
5 parts
Same as in the FTB Skies 2: Aero 1.10.0 guide
Hostile Neural Networks (HNN for short) turns mob kills into loot through Data Models, simulations and Predictions. In this pack's quest book it lives in the "Generating Resources" chapter (group "Resources & Logistics"), and it starts with the quest "Hostile Neural Networks!" quest. Here is the order I'd make things in, and why.[1][3]
Step one: the Model Framework
Start with the Model Framework. Right-click it on a mob and it builds that mob's Data Model. Attuning this way is switched on in the pack's config ([[config:config/hostilenetworks.cfg#models.Right Click To Attune]]), the same as the mod default. The pack changed this recipe, so use the one below, not one from another guide.[3][4][5]

Step two: the Deep Learner
Next, make the Deep Learner and put your Data Model inside. Every kill of that mob improves the model. All models start out Faulty, and you need to get yours to at least Basic before it can be used for Predictions. The pack changed this recipe too.[1][3][4]

Step three: Simulation Chamber and Prediction Matrix
Once a model is Basic or higher, you can stop hunting by hand. Place it in a Simulation Chamber and feed it power and Prediction Matrix items. A failed simulation gives you a Generalized Prediction, and a success gives that mob's own Prediction. Both recipes are changed by the pack, and one craft of the matrix makes 16.[1][3][4]

The chamber has two modes. Training Mode runs simulations that upgrade the model's data, and Inference Mode produces Predictions but doesn't upgrade the model. The quest a quest in "Generating Resources" covers this and comes right after the first HNN quest.[3][6]
Step four: the Loot Fabricator
Predictions only become real items in the Loot Fabricator. If a mob can drop several things, you pick which one to farm in its interface. If you automate it and no choice has been made, the machine stops working. In the pack it costs 256 FE/t to run ([[config:config/hostilenetworks.cfg#power.Loot Fab Power Cost]]), the same as the mod default. The quest a quest in "Generating Resources" comes after the Generalized Ender Prediction quest, and the pack changed this recipe.[3][4][5]

Later: the Data Center
When you have several models and want to scale up, the Data Center runs up to 25 Self Aware models at once. It needs a 7x7x7 hollow shell with an obsidian floor and black stained glass walls and ceiling, plus Data Center IO Port blocks set to different modes. The quest "Neural Data Center" quest walks you through building it and comes after the Loot Fabricator quest.[3][4][6]

How do you progress through Hostile Neural Networks?
4 parts
Same as in the FTB Skies 2: Aero 1.10.0 guide
Hostile Neural Networks has a short, clear progression path in this pack, and the quest book walks you through it. It sits in the Generating Resources chapter (chapter 8 of 31, in the Resources & Logistics group). The four quests that matter run in a line: "Hostile Neural Networks!" quest, then a quest in "Generating Resources", then a quest in "Generating Resources", then "Neural Data Center" quest.[3]
Step 1: Data models and the Deep Learner
The first quest has you make a Model Framework and right-click it on a mob to gather that mob's Data Model. Then you craft a Deep Learner and put the model inside. From then on, every kill of that mob improves the model. To make Predictions with it, the model has to reach at least the Basic tier.[3]

Step 2: Simulation Chamber and Predictions
The second quest asks for a Simulation Chamber, a Prediction Matrix and one of the Generalized Predictions. Put a Basic-tier (or better) Data Model in the chamber, feed it Prediction Matrices and power, and it runs simulations as if you were killing that mob. The power cost per simulation depends on the mob's rarity.[3]
A failed simulation gives you a Generalized Prediction, and a successful one gives you that mob's own Prediction. The chamber has two modes: Training Mode upgrades the model's data, while Inference Mode produces predictions without upgrading the model.[3]

Step 3: Loot Fabricator
The Loot Fabricator is the machine that turns a mob's Predictions into actual loot when powered. Some mobs drop more than one loot type, so you pick which one to farm in its interface. It remembers that choice when you automate it, and if no choice has been made it stops working. You can also switch it to Queue Mode to cycle through a list of outputs instead of one fixed drop.[3]

Step 4: The Neural Data Center
The last quest in the line is the Data Center multiblock. It is a 7x7x7 structure that runs up to 25 Self Aware data models at the same time. You need the Data Center block and Data Center IO Port blocks, plus obsidian and black stained glass for the shell.[3]
- Build a 7x7 obsidian platform at the bottom.[3]
- Raise black stained glass walls and leave the inside hollow.[3]
- On the outer bottom layer, place the Data Center block and 3 IO Ports, each set to a different mode: Energy, Inputs and Outputs.[3]
- Optionally add a fourth Port set to Models for automatic input of data models. It is not required.[3]
If the multiblock is built correctly, a blue outline shows around it. Otherwise, click the Data Center block for more details.[3]

Which FTB Skies 2: Aero quests use Hostile Neural Networks?
2 parts
Same as in the FTB Skies 2: Aero 1.10.0 guide
All of the quests for this mod sit in one chapter of the pack's quest book: Generating Resources. It is chapter 8 of 31, in the group Resources & Logistics, and it holds 99 quests that cover many other resource mods too. Hostile Neural Networks gets a short chain of four quests, and each one comes after the previous one.[3]
The quest chain, in order
- "Hostile Neural Networks!" quest is the start of the chain. It asks for a Model Framework and a Deep Learner. You right-click the Model Framework on a mob to gather its Data Model, then put that model in the Deep Learner. Every kill of that mob then improves the model. To make Predictions from it, you need to level it up to at least the Basic tier.[3]
- a quest in "Generating Resources" comes after the first quest. It asks for a Simulation Chamber, a Prediction Matrix, and one of the Overworld, Nether or End predictions (Generalized Overworld Prediction, Generalized Nether Prediction or Generalized Ender Prediction).[3]
- a quest in "Generating Resources" comes after the Prediction quest. It asks for the Loot Fabricator.[3]
- "Neural Data Center" quest comes after the Loot Fabricator quest. It asks for the Data Center, the Data Center IO Port, Obsidian and Black Stained Glass.[3]
What each quest teaches
The Simulation Chamber needs a Data Model that is at least Basic tier. Give it Prediction Matrices and power and it runs simulations as if you were killing that mob. The power per simulation depends on the rarity of the mob. A failed simulation gives you a Generalized Prediction, and a success gives you that mob's own Prediction. It has two modes: Training Mode upgrades the model's data, while Inference Mode produces predictions without upgrading the model.[3]
The Loot Fabricator turns Mob Predictions into actual loot when powered. If a mob can drop more than one type of loot, you pick which one to farm in its interface. When you automate it, it remembers your choice, but if no choice has been made the machine stops working. You can also switch it to Queue Mode to cycle through a list of outputs instead of producing one fixed drop.[3]
The Data Center is a 7x7x7 multiblock that runs up to 25 Self Aware data models at the same time. You build it with a 7x7 Obsidian platform at the bottom and Black Stained Glass walls, leaving the inside hollow. The Data Center block and 3 IO Ports go on the outer bottom layer, each set to a different mode: Energy, Inputs and Outputs. You can optionally add a fourth port set to Models for automatic input of data models, but it is not required.[3]
