What is Habituation?

Habituation is a fundamental concept in psychology and neuroscience that refers to a decrease in response to a repeated or continuous stimulus over time. 

1.     Definition:

  • Habituation is a form of non-associative learning where an organism's response to a stimulus decreases after repeated or prolonged exposure to that stimulus.
  • It is a simple form of learning that involves the brain's ability to filter out irrelevant or non-threatening stimuli to focus on more important or novel information.

2.     Behavioral Response:

  • In the context of infant research and developmental psychology, habituation is often used as a method to study cognitive processes in young children who cannot verbally communicate their perceptions.
  • During habituation experiments, infants are presented with a stimulus repeatedly until they show a decreased interest or response to that stimulus.

3.     Experimental Procedure:

  • Habituation experiments typically involve presenting a stimulus repeatedly to the infant until a decrease in attention or response is observed.
  • Once habituation occurs, a new or novel stimulus is introduced to assess the infant's ability to discriminate between familiar and unfamiliar stimuli.
  • The recovery of attention or response to the novel stimulus after habituation indicates that the infant has detected a change in the environment.

4.     Importance:

  • Habituation is a valuable tool in developmental research as it allows researchers to study infants' perceptual abilities, memory processes, and cognitive development.
  • By measuring habituation and dishabituation responses in infants, researchers can gain insights into how infants perceive and process information in their environment.

5.     Application:

  • Habituation is not limited to infant research and is widely used in various fields of psychology and neuroscience to study learning, memory, sensory processing, and attention.
  • It provides a simple yet effective method to investigate how organisms adapt to their environment and filter out repetitive or irrelevant stimuli.

In summary, habituation is a basic learning process characterized by a decrease in response to a repeated stimulus. In the context of infant research, habituation experiments are used to study cognitive processes and perceptual development in young children. This form of learning plays a crucial role in how organisms adapt to their surroundings and prioritize relevant information for processing.

Relation of Model Complexity to Dataset Size

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

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

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 ...

Maximum Stimulator Output (MSO)

Maximum Stimulator Output (MSO) refers to the highest intensity level that a transcranial magnetic stimulation (TMS) device can deliver. MSO is an important parameter in TMS procedures as it determines the maximum strength of the magnetic field generated by the TMS coil. Here is an overview of MSO in the context of TMS: 1.   Definition : o   MSO is typically expressed as a percentage of the maximum output capacity of the TMS device. For example, if a TMS device has an MSO of 100%, it means that it is operating at its maximum output level. 2.    Significance : o    Safety : Setting the stimulation intensity below the MSO ensures that the TMS procedure remains within safe limits to prevent adverse effects or discomfort to the individual undergoing the stimulation. o Standardization : Establishing the MSO allows researchers and clinicians to control and report the intensity of TMS stimulation consistently across studies and clinical applications. o   Indi...

Supervised Learning

What is Supervised Learning? ·     Definition: Supervised learning involves training a model on a labeled dataset, where the input data (features) are paired with the correct output (labels). The model learns to map inputs to outputs and can predict labels for unseen input data. ·     Goal: To learn a function that generalizes well from training data to accurately predict labels for new data. ·          Types: ·          Classification: Predicting categorical labels (e.g., classifying iris flowers into species). ·          Regression: Predicting continuous values (e.g., predicting house prices). Key Concepts: ·     Generalization: The ability of a model to perform well on previously unseen data, not just the training data. ·         Overfitting and Underfitting: ·    ...
