# Emergent Semantics — Model_1024_FLOAT (335M)

This repository provides **Model_1024_FLOAT (335M)** — an **ablation model** from the paper:

[📚 Paper (Emergent Semantics Beyond Token Embeddings: Transformer LMs with Frozen Visual Unicode Representations)](https://huggingface.co/papers/2507.04886) -

[📚 Paper (Growing Transformers: Modular Composition and Layer-wise Expansion on a Frozen Substrate)](https://huggingface.co/papers/2507.07129) -

[📚 Blog Article](https://huggingface.co/blog/Bochkov/emergent-semantics-beyond-token-embeddings)

This checkpoint is designed to isolate the effect of **float-valued / normalized frozen embeddings** versus **binary frozen embeddings**, while keeping the Transformer backbone and training setup the same.

---

## What this ablation is

**Model_1024_FLOAT** uses a frozen embedding table where:

- **`n_embed = 1024`** (embedding dimensionality equals `d_model`)
- Each token embedding is a **float vector**
- The embedding vectors are derived from a **random (non-semantic) codebook** and then **normalized** (e.g., L2 normalization) to control scale
- The embedding weights are **frozen** (`requires_grad=False`) for the entire training run

This model is part of an ablation series that tests whether differences in training dynamics / downstream reasoning come from:
- semantic structure in embeddings (hypothesis: not required),
- *or simply* numeric properties like dtype/scale/normalization.

---

## Relation to other models in the collection

- Compared to **Model_1024_BIT (335M)**:
  - Same backbone (`d_model=1024`, 16 layers, 32 heads, RoPE, GELU)
  - Same embedding dimensionality (`n_embed=1024`)
  - Difference is the embedding representation:
    - **1024_BIT:** frozen random **binary** vectors
    - **1024_FLOAT:** frozen random **float** vectors with **normalization**

- Compared to **Model_UNI_GLYPH (335M)**:
  - Same embedding dimensionality and frozen setup
  - UNI_GLYPH embeddings come from glyph-rendering + PCA; here embeddings are random and intended to be non-semantic

- Compared to **Model_unfrozen (335M)**:
  - Same architecture
  - Here embeddings are frozen; in the baseline they are trainable

Because `n_embed=1024`, this model is in the same **parameter-count class (~335M)** as UNI_GLYPH and the unfrozen baseline.

## Tokenizer

The intended tokenizer is **bvv241-2-3**:

- https://huggingface.co/Bochkov/bvv241-2-3

You can load the tokenizer either from this model repo (if included) or from the standalone tokenizer repo. The key requirement is **exact vocab alignment**.

## How to use (Transformers)

```python

import torch
from transformers import AutoTokenizer, AutoModelForCausalLM

tokenizer = AutoTokenizer.from_pretrained("Bochkov/emergent-semantics-model-1024-float-335m")
model = AutoModelForCausalLM.from_pretrained("Bochkov/emergent-semantics-model-1024-float-335m", trust_remote_code=True).to('cuda')

inputs = torch.tensor([tokenizer.encode("Question: What is the capital of Japan?\nAnswer:")], dtype=torch.long, device='cuda')

outputs = model.generate(
    inputs, 
    max_new_tokens=10,
    do_sample=False
)
print(tokenizer.decode(outputs[0].tolist()))

#Question: What is the capital of Japan?
#Answer:Tokyo Metropolitan 

```

---

## Intended use

Research-only checkpoint intended for:

- Studying **emergent semantics** with a frozen random float codebook
- Isolating the impact of **normalization / vector scale** in frozen embeddings
- Comparisons against **1024_BIT** and **UNI_GLYPH** under identical backbone/training conditions

Not intended for production deployment (no safety/instruction tuning).
