Our predictive analytics solutions have been used in different industries, showing how powerful and flexible machine learning can be in solving complex problems. Here are some examples that highlight the impact of our work. We developed a COVID-19 prediction tracker to calculate the risk of infection and the potential number of patients in specific locations within Israel. Our client aimed to help flatten the COVID-19 curve in Israel, a leader in vaccination efforts. We were tasked with predicting the spread and infection risk of COVID-19, facing challenges such as rapid disease spread, environmental changes, and the need for precise predictions at the city district level. Having neural networks and deep learning techniques in our arsenal, we took on the challenge: Recurrent Neural Networks (RNN) We used an artificial RNN, specifically long short-term memory (LSTM), to handle the dynamic nature of the pandemic and preserve long-term memory for time-series data related to infection rates. Data Normalization We managed to normalize data for both the beginning of the epidemic and real-time predictions, addressing statistical errors at different epidemic stages. Embedding Layers Added to the model to compress and represent city-specific data accurately, enabling the ML model to understand and predict interactions within the data. Risk Scale Development Created a risk scale (rating from 1 to 8) to detect the chances of infection in specific locations, using confirmed COVID-19 data and social behavior data. The solution provided precise predictions for epidemic development across Israel, offering accurate forecasts for around 300 towns and city districts. Specifically, the model accurately predicted infection rates with an error margin of less than 5%. The prediction accuracy improved public health responses, reducing infection rates by 20% in highly targeted areas We created a marketing forecasting solution for real estate businesses, increasing house sales by 16.5 times per month. One of our American real estate clients faced the problem of low sales. To address this, they decided to boost the number of estate buyers through ML-driven targeted advertising. We used historical sales data on transactions, loans, and estimated property values to build an ML model for highly targeted advertising: Data Usage Used ATTOM datasets (US nationwide property data) related to ownership status and seasonality to create a prediction model that accounted for sales fluctuations. Model Parameters Considered period of ownership, equity position, and actual residence for precise ad targeting, leading to significant sales growth.
