24 alternatives to Neural emotion matrix for NPCs

Hey! I built this system to humanize NPCs by giving them emotions using Rust and ML. The system provides emotion coordinates (based on Russell's circumplex model) from text input or actions, with persistent emotional memory per entity. Think NPCs that remember how they feel about specific players or events. I pre-trained a DistilBERT model on ~1k video game dialogues (Skyrim, Cyberpunk, etc.) and plan to extract and evaluate 100k+ dialogues soon. However studio/team can manually add dialogues to enrich their own dataset. The matrix doesn't generate dialogue, it only analyzes content.…

Neural Emotion Matrix for NPCs is a Rust-based system that analyzes text and actions to assign emotional states to video game characters. Built using DistilBERT machine learning, it maps emotions onto Russell's… Below are 24 products that do a similar job, ranked by how close each is in meaning and then by launch-day votes.

    The Emotion Engine has 32 MB of RAM total, so the trick is streaming weights from CD-ROM one matrix at a time during the forward pass — only activations, KV cache and embeddings live in RAM. This means models bigger than the RAM can still run, they just read more from disc. Had to build a custom quantized format (PSNT), hack endianness, write a tokenizer pipeline, and most of the PS2 SDK from scratch (releasing that separately). The model itself is also custom — a 10M param Llama-style architecture I trained specifically for this. And it works. On real hardware.

    I built over the last two years a human-like neural network chess engine that tries to predict your rating from a single game. It automatically adapts to your play and tries to play like a human at your level would play, giving you a balanced game. At the core I’m using an AlphaZero / Leela Chess Zero style neural network that I have trained on 1 billion human games from the lichess.org open database. Around this network I have built a chess engine in Rust with algorithms that use the outputs from the NN to produce human-like moves at a given rating from beginner to world champion, as…

    You talk, and it automatically builds a visual network of your beliefs, thoughts, desires, and more. The system extracts concepts like beliefs, emotions, and cognitive distortions, then updates a force-directed graph showing how everything connects. Recurring nodes naturally drift toward the center as the graph expands, revealing your core themes. It isn’t intended for therapeutic use. It’s a tool that makes you introspect and helps uncover the driving factors behind your issues instead of trying to solve the problem and suggest solutions (although you can ask it for solutions when needed).…

    Smallville can be used to create NPCs with the same level of realism as human players without having to pre-program interactions. The agents store and retrieve past memories which they use to create plans so they can decide where to move, what to say, and how to react to observations. Agents are also capable of interacting with the world around them to change the state of objects on their own. This project was intended to make it easy for anyone to create custom simulations and my attempt to recreate Generative Agents: Interactive Simulacra of Human Behavior. I’ve been working on Smallville…

    I work on real-time voice/video AI at Tavus and for the past few years, I’ve mostly focused on how machines respond in a conversation. One thing that’s always bothered me is that almost all conversational systems still reduce everything to transcripts, and throw away a ton of signals that need to be used downstream. Some existing emotion understanding models try to analyze and classify into small sets of arbitrary boxes, but they either aren’t fast / rich enough to do this with conviction in real-time. So I built a multimodal perception system which gives us a way to encode visual…
