The Sense of Self: Reflected Self-Appraisal and Social Comparison

The Sense of Self: Reflected Self-Appraisal and Social Comparison

According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Area of Science:

Computational Biology
Artificial Intelligence in Drug Discovery
Image-based High-Content Screening

Background:

Cell Painting is a powerful image-based assay for understanding drug mechanisms and off-target effects.
Traditional feature extraction methods like CellProfiler are computationally expensive and require extensive parameter tuning.
There is a need for more efficient and automated approaches to analyze Cell Painting data.

Purpose of the Study:

To evaluate the effectiveness of self-supervised learning (SSL) models for Cell Painting image analysis.
To compare the performance of SSL-derived features against traditional methods like CellProfiler.
To assess the reproducibility, biological relevance, predictive power, and transferability of SSL features.

Main Methods:

Trained SSL models (DINO, MAE, SimCLR) on a subset of the JUMP Cell Painting dataset.
Extracted image representations using these SSL models.
Assessed model performance on tasks including drug target classification, gene family classification, and bioactivity prediction.

Main Results:

The DINO SSL model outperformed CellProfiler in drug target and gene family classification, with significantly reduced computational time and cost.
DINO demonstrated strong generalizability, outperforming CellProfiler on an unseen dataset of genetic perturbations without fine-tuning.
SSL models achieved performance comparable to supervised methods in bioactivity prediction, with only a minor gap.

Conclusions:

Self-supervised learning offers an effective and efficient approach for morphological profiling using Cell Painting images.
SSL models, particularly DINO, provide powerful, generalizable representations that can enhance drug discovery pipelines.
This study highlights promising research directions for AI-driven analysis of image-based biological data.
