Peer tutors were given beforehand an orientation on the process of peer learning. The training of tutors plays an important role in the productivity of peer tutoring (Ali & Anwer, 2015). The peer tutors studied the comment of the teacher to the papers and then started discussing in general the comment in their papers.

Impact Of Peer Tutoring On Learning Of Students

This paper compares both control approaches and proposes a novel algorithm called reinforced predictive control (RL-MPC) that merges their relative merits. First, the complementarity between RL and MPC is emphasized on a conceptual level by commenting on the main aspects of each method. Second, the RL-MPC algorithm is described that effectively combines features from each approach, namely state estimation, dynamic optimization, and learning. Finally, MPC, RL, and RL-MPC are implemented and evaluated in BOPTEST, a standardized simulation framework for the assessment of advanced control algorithms in buildings.

Imagine yourself in your childhood trying to learn to ride a bicycle for the first time. Your parent or guardian had supported you to keep balance and instructed you sometimes. But the most important thing is that they did not fully supervise you during your learnings.

Bellman Optimality Equation

Results revealed that peer tutoring was effective in increasing mathematics subject mastery; however, it had not been effective in reducing mathematics anxiety. Moreover, albeit insignificantly, as the participants’ subject mastery increases, their anxiety decreases, and that mathematics anxiety is an insignificant currency trading tips predictor of subject mastery. The findings implicate that a peer tutoring program can be beneficial in equipping general education prospective teachers with sufficient content knowledge and confidence to teach mathematics; hence, further research on a functional peer tutoring process is recommended.

  • It does not only benefit the students in academics but also help the students in developing their communication and interpersonal skills .
  • The original R-CNN paper suggests the AlexNet convolutional neural network for feature extraction and a support vector machine for classification.
  • Q-Value Updation We can not overwrite the newly computed Q-value with the older value.
  • Object detection is a supervised machine learning problem, which means you must train your models on labeled examples.

Research has consistently shown that teachers’ epistemological beliefs have a significant impact on their teaching and teacher effectiveness in the teaching- learning process. This study investigated epistemological beliefs of teacher educators in higher education institutions and teacher education institutes in Khyber Pakhtunkhwa . Of the 212 teacher educators of the study population, the data were collected through stratified random sampling from 145 respondents.

The Future Of Security: Unifying Video And Access Control Technologies

Part of the Paper A learning plan was developed to make the sessions structured. Organized peer tutoring can give greater results compared to unorganized peer tutoring . After the discussion based on the learning plan of the lecture and activities, students were given assignment to write the introduction. The object detection network is trained on the annotated data until it can find regions in images that correspond to each kind of object.

The environment in RL refers to the outside world of an agent or physical world in which the agent operates.

What Are Graph Neural Networks Gnn?

Instead, you by yourself learned from your mistakes and tried again and again. After sufficient practice, your brain adapted to this new learning and you eventually became able to ride a bicycle keeping balance on both sides. •RL-MPC enables learning and meets Торговля на колебаниях the constraints with similar performance to MPC. •MPC effectively uses the controller model while pure RL violates the constraints. Now that we have defined the basic equations for solving an RL problem, our focus now should be to find an optimal solution .

The region selector generates around 2,000 regions of interest for each image. The above property can be observed in the equation as we find q∗(s′, a′) which denotes the expected return after choosing an action a in state s which is then maximized to gain the optimal Q-value. In RL, the agent selects an action from a given state, which results in transitioning to a new state, and the agent receives rewards based on the chosen action. This process happens sequentially which creates a trajectory that represents the chain/sequence of states, actions, and rewards.

Value Functions

Object detection networks bear much resemblance to image classification networks and use convolution layers to detect visual features. In fact, most object detection networks use an image classification CNN and repurpose it for object detection. Due to the COVID-19 outbreak, which was declared as a pandemic in 2020 by the World Health Organization, many educational institutions around the world started distance education. However, since distance education is an unusual field for the stakeholders of education, this sudden change created a chaos both for institutions in terms of providing the necessary infrastructure and for educators in terms of redesigning instruction techniques and tools. J. Topping & Foggie saying that peer tutoring might improve both personal and social development as well as motivation and opportunities to individualize instructions.

This function gives us the value which is the expected return starting from state s at time step t and following policy π afterward. The process of learning is an incremental exploration of a domain; we do not learn the concepts in a domain in an isolated manner, but instead augment our existing knowledge with new concepts. Consequently, when teaching a new concept to a student, her existing knowledge should be employed in a way which forex trading learning books facilitates the process of learning. That is the reason that Vygotsky supported peer tutoring as a useful approach for tutees as well as for tutors. Vygotsky also acknowledged that peer tutoring does well in case of children having some problems or disabilities when engaged with more competent partners (Ali, Anwer, & Jaffar, 2015). Vygotsky further classified the children into three categories on the basis of individual differences .

Medical Image Analysis

The CNN uses fully connected layers to encode the feature maps into a single-dimensional vector of numerical values. You can always create and test your own convolutional neural network from scratch. But most machine learning researchers and developers use one of several tried and tested convolutional neural networks such as AlexNet, VGG16, and ResNet-50.

Understanding The Bellman Optimality Equation In Reinforcement Learning

•A summary of all deep learning algorithms used in medical image analysis is given. Considering the agent following an optimal policy, the latter state s′ will be the state from we can take the best possible next action a′ at time t+1. The rewards in RL is nothing but a kind of feedback that is given to the agent based on the action of the agent.

What Is Reinforcement Learning?

In particular, comparisons are often used in descriptions in order to reduce the cognitive load on the hearer. The results are illustrated in the PEBA–II natural language generation биржа system. First, a region selector uses “selective search,” algorithm that find regions of pixels in the image that might represent objects, also called “regions of interest” .

Moreover, it is also suggested that future research be conducted on peer tutoring for other subject areas and prolonged period of peer tutoring sessions. ABSTRAK Penguasaan subjek dan kebimbangan matematik mempengaruhi prestasi guru dalam mengajar subjek. Kajian eksperimen kuasi ini bertujuan untuk mengetahui kesan tunjuk ajar rakan sebaya terhadap penguasaan subjek matematik dan kebimbangan matematik dalam kalangan guru pelatih. 35 pelajar Sarjana Muda Pendidikan Rendah terlibat sebagai pelajar dan 32 pelajar Sarjana Muda Pendidikan Menengah dengan pengkhususan Matematik terlibat sebagai pengajar. Data kuantitatif dianalisis menggunakan statistik inferensi, sementara data kualitatif dianalisis menggunakan analisis tematik dan dokumen. Hasil kajian menunjukkan bahawa tunjuk ajar rakan sebaya berkesan dalam meningkatkan penguasaan subjek matematik; namun, tidak berkesan untuk mengurangkan kebimbangan matematik.

Object Detection Datasets

For example, say you want to train a neural network to detect all 1,000 classes of objects contained in the popular open-source dataset ImageNet. In that case, your output layer will have 1,000 numerical outputs, each of which contains the probability of the image belonging to one of those classes. Peer tutoring provides an opportunity to students of diverse abilities to work on academic tasks in pairs, in a democratic, cooperative and friendly approach. In this context, the study was an attempt to analyse how peer tutoring played the said role in enhancing the academic achievements of tutors and tutees at secondary level in reference to the key levels of the cognitive domain. The study explored data from 40 purposefully selected participants of ANSI school Mardan, by applying the Pre-test Post-test Equivalent Group Design and conducting achievement tests before and after the treatments in order to accomplish the target objectives.

The results indicate that pure RL cannot provide constraint satisfaction when using a control formulation equivalent to MPC and the same controller model for learning. The new RL-MPC algorithm can meet constraints and provide similar performance to MPC while enabling continuous learning and the possibility to deal with uncertain environments. Peer learning is a broad learning strategy, with the results of the research that Peer tutoring is a highly effective way for the students to learn from each other. It does not only benefit the students academically, but also helps the students in developing their communication and interpersonal skills . Object detection is a supervised machine learning problem, which means you must train your models on labeled examples.


At times when you fell down from a bicycle, you understood that it was not the right way to ride a bicycle, therefore you tried something different, and at times when you were able to keep the balance for a longer time, then you would know that I am doing the right way. There is no direct supervision available, but to compensate for this, we have feedbacks to improve the learning. This work presents some ideas that might be used in classes to illustrate and talk about these roles. The experience we have had with students to whom these ideas have been presented shows that understanding these roles helps them.
