Bias is the difference between a model's predicted values and the correct values being predicted. Models with high bias oversimplify the data and have high error rates. Overfitting occurs when a model learns the noise in addition to the underlying patterns in the training data, resulting in low bias but high variance. Underfitting happens when a model cannot capture the underlying patterns due to being too simple, resulting in high bias but low variance. The bias-variance tradeoff aims to balance a model's complexity to avoid underfitting and overfitting.
Many community learning tools can be trained to produce a variety of results. Individual algorithms can be stacked on top of each other or rely on a "group of models" method to evaluate multiple methods for a system. In some cases, multiple datasets are collected and combined.

A statistical model or a machine learning algorithm is said to have underfitting when a model is too simple to capture data complexities. It represents the inability of the model to learn the training data effectively result in poor performance both on the training and testing data. In simple terms, an underfit model’s are inaccurate, especially when applied to new, unseen examples. It mainly happens when we uses very simple model with overly simplified assumptions. To address underfitting problem of the model, we need to use more complex models, with enhanced feature representation, and less regularization.
A statistical model is said to be overfitted when the model does not make accurate predictions on testing data. When a model gets trained with so much data, it starts learning from the noise and inaccurate data entries in our data set. And when testing with test data results in High variance. Then the model does not categorize the data correctly, because of too many details and noise. The causes of overfitting are the non-parametric and non-linear methods because these types of machine learning algorithms have more freedom in building the model based on the dataset and therefore they can really build unrealistic models. A solution to avoid overfitting is using a linear algorithm if we have linear data or using the parameters like the maximal depth if we are using decision trees.

Semi-Supervised Learning is a technique that combines the benefits of supervised learning (performance, intuitiveness) with the ability to use cheap unlabeled data (unsupervised learning). With all the cheap data available, Semi Supervised Learning will get bigger in the coming months. This episode of Machine Learning Made Simple will go into SSL, how it works, transduction vs induction, the assumptions SSL algorithms make, and how SSL compares to human learning.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.

2. What is bias?
Bias is the difference between the average prediction of our model and the
correct value which we are trying to predict. Model with high bias pays very
little attention to the training data and oversimplifies the model. It always
leads to high error on training and test data.
3. overfitting
In supervised learning, overfitting happens when our model captures the
noise along with the underlying pattern in data. It happens when we train our
model a lot over noisy dataset. These models have low bias and high variance.
These models are very complex like Decision trees which are prone to
overfitting.
4. When a mode is built using so many predictors that it captures noise along
with the underlying pattern then it tries to fit the model too closely to the
training data leaving very less scope for generalizability. This phenomenon is
known as Overfitting.
Low bias error, High variance error
This is a case of complex representation of a simpler reality
Example- Decision tress are prome to Overfitting
5. underfitting
In supervised learning, underfitting happens when a model unable to capture
the underlying pattern of the data. These models usually have high bias and
low variance. It happens when we have very less amount of data to build an
accurate model or when we try to build a linear model with a nonlinear data.
Also, these kind of models are very simple to capture the complex patterns in
data like Linear and logistic regression.
6. UNDERFITTING
When a model is unable to capture the essence of the training data properly
because of low number of parameters then this phenomenon is known as
Underfitting.
High bias error, Low variance error
This can also happen in the cases where we have very less amount of data to
build an accurate model.
This situation can also arise if we try to build linear model with non-linear
data.
Example- Linear regression and logistic regression models might face this

10. Why is Bias Variance Tradeoff?
If our model is too simple and has very few parameters then it may have high
bias and low variance. On the other hand if our model has large number of
parameters then it’s going to have high variance and low bias. So we need to
find the right/good balance without overfitting and underfitting the data.
This tradeoff in complexity is why there is a tradeoff between bias and
variance. An algorithm can’t be more complex and less complex at the same
time.
