Neuron Classification

SPCNNet distinguishes itself from traditional and other deep learning methods by its ability to directly leverage 3D structural information and biologically inspired spiking mechanisms, leading to superior classification performance.

Feature Traditional/Image-based Methods SPCNNet Approach
3D Data Handling
  • Often loses 3D structural information (projection to 2D, geometric feature extraction)
  • Relies on derived or projected data, not raw 3D
  • Directly processes raw 3D point clouds
  • Preserves comprehensive 3D morphological context
Feature Representation
  • Relies on manual geometric features or 2D image features
  • Feature extraction often lacks a unified standard
  • Learns discriminative features from spike signals on point clouds automatically
  • Captures complex spatiotemporal patterns
Computational Model
  • Traditional ANNs (continuous signals), less biologically plausible
  • Higher computational cost and energy consumption
  • Spiking Neural Networks (SNNs) - event-driven, energy-efficient, biologically plausible
  • Sparse activation reduces unnecessary computations
Information Encoding
  • Continuous analog signals
  • Limited explicit temporal information processing
  • Temporal spike trains, preserving rich spatiotemporal information
  • Aligns with dynamic information processing in the brain
Performance
  • Lower accuracy, especially on complex 3D neuron data (e.g., ~60-80% for PointNet, CNN)
  • Results vary greatly across datasets
  • Achieves superior classification accuracy (84.63%-85.42%)
  • Demonstrates high stability and generalization across diverse datasets

The success of SPCNNet is attributed to its foundational components, particularly the Farthest Point Sampling (FPS) algorithm for robust data representation and the Leaky Integrate-and-Fire (LIF) neuron model for efficient, brain-inspired computation.

Impact of Core SPCNNet Innovations

Context: Our ablation studies highlight the critical role of Farthest Point Sampling (FPS) for data representation and Leaky Integrate-and-Fire (LIF) neurons for efficient processing.

Problem: Ensuring effective 3D point cloud representation and biologically plausible, efficient feature learning is crucial for high-accuracy neuron classification.

Solution: We integrated Farthest Point Sampling (FPS) to preserve key topological points in 3D data and utilized Leaky Integrate-and-Fire (LIF) neurons to process data as spike trains, enhancing spatiotemporal learning and energy efficiency.

Results: Experiments on the zebrafish dataset demonstrated that FPS improved accuracy by over 12% compared to random sampling. Furthermore, replacing traditional ReLU activation with LIF neurons yielded an additional +8.34% increase in classification accuracy (from 77.08% to 85.42% for FPS based). This synergistic combination validates our design choices for optimal performance.
