# ๐งฌ CANLoc โ Protein Subcellular Localization Predictor
|
| 2 |
-
|
| 3 |
-
CANLoc is a production-ready machine learning web application for predicting the **subcellular localization of proteins** directly from amino acid sequences.
|
| 4 |
-
It provides accurate, fast, and interpretable predictions through a modern deep-learningโassisted pipeline and an interactive web interface.

## ๐ฌ Model Overview
|
| 9 |
-
|
| 10 |
-
CANLoc combines:
|
| 11 |
-
|
| 12 |
-
- **ESM2 (Transformer-based protein language model)**
|
| 13 |
-
Used for extracting rich sequence embeddings without alignment.
|
| 14 |
-
|
| 15 |
-
- **Mean pooling of residue embeddings**
|
| 16 |
-
Produces fixed-length feature vectors.
|
| 17 |
-
|
| 18 |
-
- **XGBoost classifier**
|
| 19 |
-
Trained on curated protein datasets for robust multiclass prediction.
|
| 20 |
-
|
| 21 |
-
### Predicted Classes
|
| 22 |
-
- Cytoplasm
|
| 23 |

-
- Mitochondria
|
| 26 |
-
|
| 27 |
-
Each prediction includes **class probabilities** and **confidence visualization.**

## โ๏ธ Evaluation & Validation
|
| 73 |
-
|
| 74 |
-
The model was evaluated using:
|
| 75 |
-
- Train/test split
|
| 76 |
-
- 10-fold stratified cross-validation
|
| 77 |
-
- Precision, recall, F1-score
