Unveiling Hidden Neural Codes: SIMPL – A Scalable and Fast Approach for Optimizing Latent Variables and Tuning Curves in Neural Population Data

Dr. Rishabh Pathak
This research paper presents SIMPL (Scalable Iterative Maximization of Population-coded Latents), a novel, computationally efficient algorithm designed to refine the estimation of latent variables and tuning curves from neural population activity. Latent variables in neural data represent essential low-dimensional quantities encoding behavioral or cognitive states, which neuroscientists seek to identify to understand brain computations better. Background and Motivation Traditional approaches commonly assume the observed behavioral variable as the latent neural code. However, this assumption can lead to inaccuracies because neural activity sometimes encodes internal cognitive states differing subtly from observable behavior (e.g., anticipation, mental simulation). Existing latent variable models face challenges such as high computational cost, poor scalability to large datasets, limited expressiveness of tuning models, or difficulties interpreting complex neural network-based functio...

Dr. Rishabh Pathak

Analytical research is a type of research design that involves the critical analysis and interpretation of existing data, information, or knowledge to make a comprehensive evaluation, draw conclusions, and generate new insights. Unlike descriptive research, which focuses on describing the characteristics of a subject, analytical research aims to examine the underlying relationships, patterns, causes, and effects within the data to gain a deeper understanding of the subject under study.

Key features of analytical research include:

1.     Use of Existing Data: Analytical research relies on existing data, information, theories, or literature as the primary source of analysis. Researchers critically evaluate and synthesize available data to uncover patterns, trends, and relationships that may not be immediately apparent.


2.     Critical Evaluation: Analytical research involves a critical examination of data to identify strengths, weaknesses, inconsistencies, and gaps in the existing knowledge. Researchers assess the quality and reliability of the data sources and the validity of the analytical methods used.


3.     Hypothesis Testing: In analytical research, researchers may formulate hypotheses based on existing theories or observations and test these hypotheses using analytical methods. The goal is to determine the validity of the hypotheses and draw conclusions based on the analysis.


4.     Data Interpretation: Analytical research focuses on interpreting data to uncover underlying meanings, relationships, and implications. Researchers analyze data using various techniques such as statistical analysis, content analysis, comparative analysis, or qualitative coding to derive insights and conclusions.


5.     Causal Relationships: Analytical research often seeks to establish causal relationships between variables by examining the effects of one variable on another. Researchers aim to identify the factors that influence outcomes and understand the mechanisms underlying these relationships.


6.     Theory Development: Analytical research contributes to theory development by refining existing theories, proposing new hypotheses, or generating theoretical frameworks based on the analysis of data. It helps in advancing knowledge and understanding within a particular field of study.


7.     Applications: Analytical research is commonly used in social sciences, business, economics, psychology, and other disciplines to analyze complex phenomena, trends, behaviors, and relationships. It provides a systematic approach to examining data and generating insights for decision-making and problem-solving.


Overall, analytical research plays a critical role in advancing knowledge, theory, and understanding by analyzing existing data and information in a systematic and rigorous manner. By examining relationships, patterns, and causal links within the data, analytical research contributes valuable insights and implications for further research and practice in various fields.

Relation of Model Complexity to Dataset Size

Dr. Rishabh Pathak
Core Concept The relationship between model complexity and dataset size is fundamental in supervised learning, affecting how well a model can learn and generalize. Model complexity refers to the capacity or flexibility of the model to fit a wide variety of functions. Dataset size refers to the number and diversity of training samples available for learning. Key Points 1. Larger Datasets Allow for More Complex Models When your dataset contains more varied data points , you can afford to use more complex models without overfitting. More data points mean more information and variety, enabling the model to learn detailed patterns without fitting noise. Quote from the book: "Relation of Model Complexity to Dataset Size. It’s important to note that model complexity is intimately tied to the variation of inputs contained in your training dataset: the larger variety of data points your dataset contains, the more complex a model you can use without overfitting....

Linear Models

Dr. Rishabh Pathak
1. What are Linear Models? Linear models are a class of models that make predictions using a linear function of the input features. The prediction is computed as a weighted sum of the input features plus a bias term. They have been extensively studied over more than a century and remain widely used due to their simplicity, interpretability, and effectiveness in many scenarios. 2. Mathematical Formulation For regression , the general form of a linear model's prediction is: y^ ​ = w0 ​ x0 ​ + w1 ​ x1 ​ + … + wp ​ xp ​ + b where; y^ ​ is the predicted output, xi ​ is the i-th input feature, wi ​ is the learned weight coefficient for feature xi ​ , b is the intercept (bias term), p is the number of features. In vector form: y^ ​ = wTx + b where w = ( w0 ​ , w1 ​ , ... , wp ​ ) and x = ( x0 ​ , x1 ​ , ... , xp ​ ) . 3. Interpretation and Intuition The prediction is a linear combination of features — each feature contributes prop...

Predicting Probabilities

Dr. Rishabh Pathak
1. What is Predicting Probabilities? The predict_proba method estimates the probability that a given input belongs to each class. It returns values in the range [0, 1] , representing the model's confidence as probabilities. The sum of predicted probabilities across all classes for a sample is always 1 (i.e., they form a valid probability distribution). 2. Output Shape of predict_proba For binary classification , the shape of the output is (n_samples, 2) : Column 0: Probability of the sample belonging to the negative class. Column 1: Probability of the sample belonging to the positive class. For multiclass classification , the shape is (n_samples, n_classes) , with each column corresponding to the probability of the sample belonging to that class. 3. Interpretation of predict_proba Output The probability reflects how confidently the model believes a data point belongs to each class. For example, in ...

Uncertainty Estimates from Classifiers

Dr. Rishabh Pathak
1. Overview of Uncertainty Estimates Many classifiers do more than just output a predicted class label; they also provide a measure of confidence or uncertainty in their predictions. These uncertainty estimates help understand how sure the model is about its decision , which is crucial in real-world applications where different types of errors have different consequences (e.g., medical diagnosis). 2. Why Uncertainty Matters Predictions are often thresholded to produce class labels, but this process discards the underlying probability or decision value. Knowing how confident a classifier is can: Improve decision-making by allowing deferral in uncertain cases. Aid in calibrating models. Help in evaluating the risk associated with predictions. Example: In medical testing, a false negative (missing a disease) can be worse than a false positive (extra test). 3. Methods to Obtain Uncertainty from Classifiers 3.1 ...

Uncertainty in Multiclass Classification

Dr. Rishabh Pathak
1. What is Uncertainty in Classification? Uncertainty refers to the model’s confidence or doubt in its predictions. Quantifying uncertainty is important to understand how reliable each prediction is. In multiclass classification , uncertainty estimates provide probabilities over multiple classes, reflecting how sure the model is about each possible class. 2. Methods to Estimate Uncertainty in Multiclass Classification Most multiclass classifiers provide methods such as: predict_proba: Returns a probability distribution across all classes. decision_function: Returns scores or margins for each class (sometimes called raw or uncalibrated confidence scores). The probability distribution from predict_proba captures the uncertainty by assigning a probability to each class. 3. Shape and Interpretation of predict_proba in Multiclass Output shape: (n_samples, n_classes) Each row corresponds to the probabilities of ...
