Slide 1 - AGRICULTURE: A Field for Development using AI Techniques - Lets Identify the Applications Presented by: V S K Murthy B (08407403) Singre Pawan (07305039) CS621 Course Tutor: Prof. Pushpak Bhattacharya 1 CS621-Artificial Intelligence Course Seminar
Slide 2 - Outline Talk is divided into two parts: Part-I: Why to choose “field of Agriculture” ? Identified Areas for enhancing Agriculture sector Computational Intelligence in Agriculture and Environment Part-II: Intelligent Environment Control for Plant Production Intelligent Robot in Agriculture Conclusion 2 CS621-Artificial Intelligence Course Seminar
Slide 3 - Part-I 3 CS621-Artificial Intelligence Course Seminar
Slide 4 - Why to choose “Field of Agriculture”? Sector status in India Growth of socio-economic sector in India Means of living for almost 66% of the employed class in India Acquired 18% of India's GDP Occupied almost 43% of India's geographical area Huge investment made for Irrigation facilities etc. in 11th five year plan Introduction of de-regulation in agriculture sector Opens competition for agriculture products Removal of unnecessary restrictions — movement, stocking, and so on.. Good price to farmer Substantial technology growth in coming years 4 CS621-Artificial Intelligence Course Seminar
Slide 5 - Why to choose “Field of Agriculture”? Any process growth rates can be linked with efficiency curves Due to deregulation, Agriculture has bright future insight 5 CS621-Artificial Intelligence Course Seminar
Slide 6 - Why to choose “Field of Agriculture”? Peak in the agricultural sector will again reach in near future CS621-Artificial Intelligence Course Seminar 6
Slide 7 - Identified Areas for enhancing Agriculture sector Needs monitoring on Agricultural crop conditions Weather and climate Ecosystems Decision support for agricultural planning and policy-making On the basis of AI interest Computational Intelligence in Agriculture and the Environment Optimizing different types of bio-systems Testing and fitting of quantitative models Intelligent environment control for plant production systems Intelligent robots in agriculture An expert geographical information system for land evaluation Artificial neural network for plant classification using image processing. Control of green house. 7 CS621-Artificial Intelligence Course Seminar
Slide 8 - Computational Intelligence in Agriculture and the Environment CS621-Artificial Intelligence Course Seminar 8
Slide 9 - Search procedures Exhaustive techniques (random walk) Calculus based methods (gradient methods) Partial knowledge techniques (hill climbing) Knowledge based techniques (Production rule systems, heuristic methods) Stochastic techniques (SA) Biologically inspired algorithms (GA and immune) Problems deal with optimizing bio-systems and fitting quantitative models require Refinement or processing using adaptive search procedures Bio-system Derived Algorithms (BDAs) Photosynthetic Algorithm (PA) Leaf Cellular Automate (LCA) CS621-Artificial Intelligence Course Seminar 9

Slide 15 - Hydroponic System 15 CS621-Artificial Intelligence Course Seminar
Slide 16 - 16 CS621-Artificial Intelligence Course Seminar
Slide 17 - Plant Growth Optimization Problem In plant production, good fruit yield requires an optimal balance between Vegetative growth (e.g. root, stem, leaf growth) Reproductive growth (e.g. flower and fruit growth) NNs and GA provides optimal set points of the nutrient concentration (NC). The ratio of total leaf length (TLL) to stem diameter (SD) defines as a predictor for plant production growth. 17 CS621-Artificial Intelligence Course Seminar
Slide 18 - Optimization Problem Let TLL(k)/SD(k) be the time series of TLL/SD as affected by NC(k) (k=1,......,N; N : final day) Seedling stage(1 ≤ k ≤ N ) divided into four steps: Transplanting Vegetative growth after transplanting Flowering of the first truss Fruit setting for the first truss and flowering for the second truss. Consider the value of nutrient concentration at each step is NC1, NC2, NC3, NC4 . {1≤ k ≤ N1L : step1, N1L+1 ≤ k ≤ N2L: step2, N2L+1 ≤ k ≤ N3L : step3, N3L+1 ≤ k ≤ N : step4} 18 CS621-Artificial Intelligence Course Seminar
Slide 19 - Optimization Problem Objective Function : Objective Problem Maximize F(NC) Subject to α1 ≤ NC(k) ≤ α2 19 CS621-Artificial Intelligence Course Seminar
Slide 20 - Neural Networks 20 CS621-Artificial Intelligence Course Seminar
Slide 21 - Genetic Algorithm 21 CS621-Artificial Intelligence Course Seminar
Slide 22 - Procedure of GA Step1: The Initial population consisting of several individuals Step2 : Several individuals in another population are added to original population to maintain diversity Step3 : Crossover and mutation operations are applied to the individuals Step4 : Fitness values of all individuals are calculated by NN model Step5 : Superior individuals are selected and retained for next generation Step6 : step 2 through 5 are repeated until an arbitrary condition satisfied CS621-Artificial Intelligence Course Seminar 22
