Remote Sensing Systems

India being an agricultural country, the most part of economy is depends on yield growth. Agriculture is largely dependent on rainwater and also relies on different soil variables such as aspects of nitrogen, phosphorus, potassium and climate such as temperature, precipitation, etc. The technological growth in agriculture will increase the crop productivity. Remote sensing systems like IOT systems are being more widely used in smart farming systems, these systems produce generous amount of data. Machine learning is an ongoing work that has been filed to forecast the plant based on data trends. The proposed system would integrate sensors such as Ph., Moisture, Rainfall, Temperature and Humidity to analyze the information from these sensors and to implement machine learning algorithms: Linear Regression, Decision Trees, Random Forest, and GDBoost. The most desirable crops are predicted according to the current environment. This work gives farmers a better prediction to plant what kind of crops in their farm field based on the criteria listed above in order to improve Smart Farming's productivity.

The Impact

The motion picture industry is one of the largest industries worldwide and has significant importance in the global economy. Considering the high stakes and high risks in the industry, forecast models and decision support systems are gaining importance. Several attempts have been made to estimate the theatrical performance of a movie before or at the early stages of its release. Nevertheless, these models are mostly used for predicting domestic performances and the industry still struggles to predict box office performances in overseas markets. In this study, the aim is to design a forecast model using different machine learning algorithms to estimate the theatrical success of US movies in Turkey. From various sources, a dataset of 1559 movies is constructed. Firstly, independent variables are grouped as pre-release, distributor type, and international distribution based on their characteristic. The number of attendances is discretized into three classes. Four popular machine learning algorithms, artificial neural networks, decision tree regression and gradient boosting tree and random forest are employed, and the impact of each group is observed by compared by the performance models. Then the number of target classes is increased into five and eight and results are compared with the previously developed models in the literature.

Constraint Model

The online English teaching system has certain requirements for the intelligent scoring system, and the most difficult stage of intelligent scoring in the English test is to score the English composition through the intelligent model. In order to improve the intelligence of English composition scoring, based on machine learning algorithms, this study combines intelligent image recognition technology to improve machine learning algorithms, and proposes an improved MSER-based character candidate region extraction algorithm and a convolutional neural network-based pseudo-character region filtering algorithm. In addition, in order to verify whether the algorithm model proposed in this paper meets the requirements of the group text, that is, to verify the feasibility of the algorithm, the performance of the model proposed in this study is analyzed through design experiments. Moreover, the basic conditions for composition scoring are input into the model as a constraint model. The research results show that the algorithm proposed in this paper has a certain practical effect, and it can be applied to the English assessment system and the online assessment system of the homework evaluation system algorithm system.

Simple Task

Detecting some patterns is a simple task for humans, but nearly impossible for current machine learning algorithms. Here, the "checkerboard" pattern is examined, where human prediction nears 100% and machine prediction drops significantly below 50%.
